Using CM-1 for Freezing Cells

To use CM-1 for freezing both adherent and suspension cells, follow these steps:


For adherent cells, wash and dissociate them from the culture substrate. For suspension cells, proceed directly to the next step.
Count the cells to ensure they are at the proper concentration.
Centrifuge the cells to pellet them, then resuspend in CM-1 freeze medium.
Transfer the resuspended cells into cryovials.
Use a slow-freezing method before transferring the cells to long-term storage.

Cytion’s Freeze Medium CM-1 offers a reliable solution for cryopreservation, ensuring high cell viability and functionality post-thaw for a wide range of research applications.

DMEM:Ham's F12 is a widely recognized and extensively utilized basal medium in cell culture for biological research. It serves as a fundamental source of nutrients for the growth of various mammalian cell lines, particularly when supplemented with Fetal Bovine Serum (FBS).

This unique formulation combines Dulbecco's Modified Eagle Medium (DMEM) and Ham's F-12 (Ham's Nutrient Mixture F-12) in a precise 1:1 ratio. The addition of L-glutamine further enhances its composition.

DMEM, derived from Eagle's Minimal Essential Medium (EMEM), offers an increased concentration of amino acids and vitamins compared to its predecessor. In contrast, Ham's F-12 is based on Ham's F-10 medium, providing a complementary set of essential components.

To support optimal cell growth, it is common practice to supplement DMEM:Ham's F12 with FBS at a typical concentration of 5-10%. This addition is necessary as the medium lacks growth hormones, lipids, and proteins crucial for cellular development.

DMEM:Ham's F12 incorporates a pH buffer system and is often supplemented with phenol red, a pH indicator. Cultured cells in DMEM:Ham's F12, or any medium utilizing the bicarbonate buffer system, require a controlled CO2 environment of 5-10% to maintain appropriate pH levels.

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.

Phosphate-Buffered Saline (PBS) Solution
Phosphate-buffered saline (PBS) is a widely used buffer solution in biological and chemical research. It plays a crucial role in maintaining the pH balance and osmolarity during various experimental procedures, including tissue processing and cell culture. Our PBS solution is meticulously formulated with high-purity ingredients to ensure stability and reliability in every experiment. The osmolarity and ion concentrations of our PBS closely mimic those of the human body, making it isotonic and non-toxic to most cells.

Composition of Our PBS Solution
Our PBS solution is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions. At a 1X working concentration, it contains:

8000 mg/L Sodium chloride (NaCl)
200 mg/L Potassium chloride (KCl)
1150 mg/L Sodium phosphate dibasic anhydrous (Na2HPO4)
200 mg/L Potassium phosphate monobasic anhydrous (KH2PO4)

This composition ensures an optimal pH and ionic balance, suitable for a wide range of biological applications.

Applications of Our PBS Solution
Our PBS solution is ideal for various applications in biological research. Its isotonic and non-toxic properties make it suitable for substance dilution and cell container rinsing. PBS solutions containing EDTA are effective for disengaging attached and clumped cells. However, divalent metals such as zinc should not be added to PBS, as this can cause precipitation. In such cases, Good's buffers are recommended. Additionally, our PBS solution is an acceptable alternative to viral transport medium for the transport and storage of RNA viruses, including SARS-CoV-2.
