Comments

This is a glioma IDH1R132H mutant isogenic line derived from the parental U-87MG (ATCC® HTB-14) cell line. The c.395G>A knock-in mutation encoding IDH1R132H protein expression was generated at ATCC by utilizing the CRISPR/Cas9 gene editing technology. This is a heterozygous mutation expressing the c.395G>A mutant allele. The IDH1R132H mutation in HTB-14IG has been validated at the genomic, transcript, and protein bio-functional levels.

The IDH1R132H mutation is among the most common seen in glioma and serves as an important diagnostic marker in various stages of disease in patients. This IDH1R132H mutant isogenic line HTB-14IG has been tested at ATCC for neomorphic functional activity displaying elevated levels of intra- and extracellular D-2HG above the parental U-87MG line. In addition, the HTB-14IG IDH1 mutant isogenic line displays histone hypermethylation compared to the parental line. This IDH1R132H isogenic cell model is a valuable in vitro cell-based tool for clinical diagnostics, elucidating mechanisms involved in cancer-associated differentiation, tumorigenesis and use in screening anti-cancer compounds for drug discovery and development.

Refer to the parental line U-87MG (ATCC® HTB-14) for additional background information.

Complete Growth Medium

The base medium for this cell line is Eagle's Minimal Essential Medium (EMEM; ATCC 30-2003). To make the complete medium add Fetal Bovine Serum (FBS; ATCC 30-2020) to the base medium for a final concentration of 10%.
Subculturing
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
    Cultures can be established between 2.0 x 104 and 6 x 104 viable cells/cm2.
  6. Incubate cultures at 37°C.
Interval: Maintain cultures at a cell concentration between 2 X 104 and 1 X 105 cell/cm2.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:6 is recommended
Medium Renewal: 2 to 3 times per week
Cryopreservation Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
