WISH (ATCC® CCL-25)

Organism: Homo sapiens, human  /  Tissue: HeLa contaminant  / 

Organism Homo sapiens, human
Tissue HeLa contaminant
Product Format frozen
Morphology epithelial
Culture Properties adherent
Biosafety Level 2
Derivation
This line was originally thought to be derived from normal amnion, but was subsequently found, based on isoenzyme analysis, HeLa marker chromosomes, and DNA fingerprinting, to have been established via HeLa cell contamination.
Markers Y
Genes Expressed
The cells are positive for keratin by immunoperoxidase staining.
The cells and tumors formed from the cells are positive for Dopa decarboxylase and are negative for the TAG-72 antigen.
Comments Cells of this line contain HeLa marker chromosomes, and were derived via HeLa contamination
Complete Growth Medium Minimum essential medium (Eagle) in Earle's BSS with non-essential amino acids and 1 mM sodium pyruvate, 90%; fetal bovine serum, 10%
Subculturing
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:10 is recommended

Medium Renewal: Twice per week

Remove medium, add fresh 0.25% trypsin solution for 3 to 5 minutes, remove trypsin and let culture sit at room temperature for 5 to 10 minutes. Add fresh medium, aspirate and dispense into new flasks.
Cryopreservation
culture medium 95%; DMSO, 5%
Culture Conditions
Temperature: 37°C
