T24 Cell Line

General Information
Organism Homo sapiens, human
Cell Line Description T24 is an important human epithelial cell line derived from highly malignant and aggressive bladder transitional cell carcinoma. Initially established in an 81-year-old female patient, it is one of the earliest and most extensively studied human cancer cell lines. A notable biological characteristic of the T24 cell line is the presence of a mutated and activated HRAS (Ha-ras) oncogene, specifically a point mutation at amino acid position 12. These cells have a generation time of approximately 19 hours and are known for their high motility. While the original T24 cell line has shown limited tumorigenicity in nude mice, its derived sublines, such as T24T, have been developed to mimic advanced metastatic progression and higher malignancy.

Culture Conditions and Handling
Subculturing 1. Remove and discard the culture medium.
2. Gently rinse the cell layer with calcium- and magnesium-free PBS buffer or 0.25% trypsin-EDTA solution to remove residual serum.
3. Add 1.0 to 3.0 mL of 0.25% (w/v) trypsin-0.53 mM EDTA solution (for T75 culture flasks).
4. Observe under an inverted microscope until the cell layer disperses (usually 2 to 10 minutes). For cells that are difficult to separate, incubate at 37°C to promote detachment.
5. Add an equal volume of complete culture medium to neutralize the trypsin.
6. Gently pipette the cells and transfer them to centrifuge tubes.
7. Centrifuge at 125 x g for 5-7 minutes.
8. Resuspend the cell pellet in fresh complete culture medium and aliquot into new culture containers.
Medium Renewal 2 to 3 times per week.
Subcultivation Ratio A split ratio of 1:3 to 1:8 is recommended.
Culture Medium McCoy's 5a Medium Modified + 10% Fetal Bovine Serum (FBS). Alternatively, DMEM/F12 (1:1) + 5-10% FBS.
Culture Conditions Atmosphere: Air, 95%; CO2, 5%; Temperature: 37℃
Cryopreservation Complete growth medium supplemented with 5% to 10% (v/v) DMSO.
