Material Transfer Agreement

Description	NCI-H157 is a human non-small cell lung carcinoma (NSCLC) cell line, primarily used in cancer research to study tumorigenesis, chemotherapy resistance, and the molecular pathways involved in lung cancer progression. NCI-H157 cells are particularly useful for investigating the role of hypoxia-inducible factor-1 alpha (HIF-1α) in NSCLC. Studies have shown that HIF-1α plays a crucial role in promoting angiogenesis, proliferation, and survival of cancer cells under hypoxic conditions. Downregulation of HIF-1α via siRNA in NCI-H157 cells significantly reduces cell proliferation, induces apoptosis, and impairs the invasive ability of the tumor cells. Moreover, combination treatments using HIF-1α siRNA and chemotherapy agents, such as cisplatin (DDP), enhance the cytotoxic effects on NCI-H157 cells. The reduction of HIF-1α expression has been shown to increase the activity of apoptotic proteins like caspases 3 and 9 while decreasing the levels of anti-apoptotic proteins such as Bcl-2. Additionally, HIF-1α knockdown inhibits key signaling pathways involved in tumor growth, including the PI3K/AKT and Raf/MEK/ERK pathways. These molecular alterations contribute to the suppression of tumor cell survival and invasiveness. The NCI-H157 cell line is also responsive to various natural compounds and plant extracts. For example, extracts from Stellera chamaejasme L. have been found to induce apoptosis in NCI-H157 cells through the Fas death receptor pathway, further emphasizing the cell line's utility in evaluating novel therapeutic agents for lung cancer.

Culture Medium	RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a)
Supplements	Supplement the medium with 10% FBS
Dissociation Reagent	Accutase
Subculturing	Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.
Freeze medium	As a cryopreservation medium, we use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
Thawing and Culturing Cells	Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
Incubation Atmosphere	37°C, 5% CO₂, humidified atmosphere.
Shipping Conditions	Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
Storage Conditions	For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Sterility	Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3

RPMI 1640 Medium, also known as RPMI medium, is a highly versatile cell culture medium widely utilized in biological research to cultivate various mammalian cells. Developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at the renowned Roswell Park Comprehensive Cancer Center, this medium derived its name from its origin at the Roswell Park Memorial Institute (RPMI).
Initially designed to support the growth of human leukemic cells in both suspension and monolayer cultures, RPMI 1640 Medium has evolved through modifications by researchers and commercial suppliers to become suitable for a diverse range of mammalian cells. It is exceptionally compatible with cell lines such as HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, and carcinomas.
RPMI 1640 Medium stands apart from other cell culture media due to its unique composition. It contains a substantial amount of phosphate, amino acids, and vitamins. Notably, it encompasses biotin, vitamin B12, and PABA, absent in Eagle's Minimal Essential Medium or Dulbecco's Modified Eagle Medium. Moreover, RPMI 1640 Medium exhibits significantly elevated concentrations of vitamins inositol and choline. However, it does not contain proteins, lipids, or growth factors. Consequently, supplementation with 10% Fetal Bovine Serum (FBS) is commonly required to provide optimal conditions for cell growth.
The buffering system of RPMI 1640 Medium relies on sodium bicarbonate and necessitates a 5-10% CO2 environment to maintain a physiologically appropriate pH. The inclusion of the reducing agent glutathione further distinguishes this medium from others.

Accutase Cell Detachment Solution - 100 ml

Variants: 100 ml

Accutase Cell Detachment Solution with EDTA and Phenol Red – 100 ml

Accutase is a ready-to-use, sterile-filtered cell detachment solution designed as a gentle alternative to trypsin/EDTA for dissociating adherent mammalian cells from standard tissue culture plasticware and adhesion-coated surfaces. It combines proteolytic and collagenolytic enzyme activity in a balanced salt solution to deliver effective yet controlled dissociation, preserving cell-surface proteins and supporting high post-passage viability and rapid reattachment.

The Accutase formulation is based on Dulbecco’s phosphate-buffered saline (DPBS) with EDTA and phenol red as a visual pH indicator. The enzymes are of non-mammalian and non-bacterial origin, making Accutase particularly well suited to stem cell research, vaccine workflows, and any application where animal
- or microbially-derived contaminants must be minimised. The solution auto-inhibits at 37 °C, so no neutralising reagent or serum-containing medium is required after detachment – cells can be transferred directly into fresh medium.

Key Features

Ready-to-use 1x sterile-filtered liquid – no dilution or reconstitution required
Combined proteolytic and collagenolytic enzyme activity for gentle dissociation
Each batch standardised to a defined dissociation activity for lot-to-lot consistency
Non-mammalian and non-bacterial enzyme origin
Auto-inhibits at 37 °C – no neutralising solution needed
Formulated in Dulbecco’s PBS with EDTA
Phenol red included as visual pH indicator
pH 6.8 – 7.8

Typical Applications
Accutase gently dissociates a wide variety of adherent and sensitive cell types, including human embryonic stem cells (hESCs), human induced pluripotent stem cells (iPSCs), neural stem cells, primary neurons, and routinely cultured adherent lines such as HeLa, HEK 293, CHO, MDCK, Vero, NIH/3T3, BHK-21 and A549. Typical use cases include:

Routine subculture and passaging of adherent mammalian cells
Gentle single-cell dissociation of hESCs, iPSCs and other sensitive lines
Sample preparation for flow cytometry and FACS analysis
Analysis of cell-surface markers where epitope integrity matters
Cell migration, proliferation and apoptosis assays
Quiescence assays by serum starvation and oncogene transfection studies
Tumor cell and neural crest cell migration assays
Production scale-up in bioreactor workflows

For routine work, apply approximately 10 ml of Accutase per 75 cm2 of culture surface and incubate for 5–10 minutes at room temperature. The optimal incubation time should be determined for each cell line and should not exceed one hour. Prior to addition, rinse the cell layer with a Ca2+/Mg2+-free salt solution such as DPBS without calcium and magnesium to remove residual serum and divalent cations.

Handling & Storage
Store the unopened bottle frozen at -15 °C or below. Thaw either at room temperature or overnight at +2 °C to +8 °C. Do not thaw Accutase in a 37 °C water bath, as elevated temperatures reduce enzyme activity. After thawing, the solution can be stored for up to 2 months at +2 °C to +8 °C; do not store at room temperature. Do not pre-warm the reagent to 37 °C before application – add it directly to washed cells at room temperature. For long-term shelf life, single-use aliquoting is recommended to avoid repeated thaw cycles. Always work under aseptic conditions.

Quality
Manufactured under strict quality standards. Each batch of Accutase is sterile-filtered and tested for sterility, pH, appearance and dissociation activity to ensure consistent, reproducible performance from lot to lot.
