Description	MOLT-4 is a T lymphoblast cell line derived from the peripheral blood of a 19-year-old male patient with Acute lymphoblastic leukemia (ALL) in relapse in 1971. It is a sister cell line of MOLT-3, while MOLT-4 shows an unusual T-cell antigen receptor gamma-chain gene (T-gamma) rearrangement. MOLT-4 cells have a doubling time of around 30 hours, grow in suspension, and are tumorigenic in untreated nude mice, anti-lymphocyte serum-treated mice, and x-irradiated mice. MOLT-4 cells have a hypertetraploid chromosome number with the modal chromosome number of 95 occurring in 24% of cells but show stable and recurrent structural abnormalities of chromosomes and longer telomere length. MOLT-4 expresses a variety of T cell markers including CD1, CD2, CD3A, CD3B, CD3C, CD4, CD5, CD6, and CD7. They also express high levels of terminal deoxynucleotidyl transferase (TdT). The MOLT-4 cell line does not produce immunoglobulin or Epstein-Barr virus. The patient from whom the cells were derived had received prior multidrug chemotherapy. There is a G -> A mutation at codon 248 of the p53 gene, and P53 is not expressed. The line was initially contaminated with mycoplasma but has since been cured with antibiotics.

Medium supplements	Supplement the medium with 10% FBS
Subculturing	Maintain cultures by periodically adding or replacing the medium. Initiate cultures with a density of 2 x 10^5 cells/ml and keep the cell concentration within the range of 1 x 10^5 to 1 x 10^6 cells/ml for optimal growth.
Seeding density	1 x 10^5 cells/cm^2
Fluid renewal	2 to 3 times per week
Freezing recovery	24 to 48 hours
Freeze medium	As a cryopreservation medium, 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.
Handling of cryopreserved cultures	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.

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.

PBS

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.
