HeLa cells are positive for keratin by immunoperoxidase staining.
HeLa cells have been reported to contain human papilloma virus 18 (HPV-18) sequences.
P53 expression was reported to be low, and normal levels of pRB (retinoblastoma suppressor) were found.
HeLa S3 is a clonal derivative of the parent HeLa line (see ATCC CCL-2). S3 was cloned in 1955 by T.T. Puck, P.I. Marcus, and S.J. Cieciura. [22814]
The HeLa S3 clone has been very useful in the clonal analysis of mammalian cell populations relating to chromosomal variation, cell nutrition, and plaque-forming ability.
This line can be adapted to grow in suspension. [25952]
The cells are positive for keratin by immunoperoxidase staining.
A culture at approximately passage 400 was submitted to the American Type Culture Collection in February, 1972.
