Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Recently, it has been shown that VCaP prostate cancer cells produce the mouse xenotropic retrovirus Bxv-1, which was likely acquired by the cells during their xenotransplantation in mice.
ATCC® CRL-2876 ™ is a very slow growing cell line and can take up to 48 hours to attach post-thaw and after subcultures. It can routinely take a minimum of 2 weeks or more for cells to reach approximately 50% confluence with a dense mixture of adherent cells, floating clusters and moderate to heavy debris is always present. The cells may recover better in a T-25 flask compared to a T75 flask. Do not discard any floating cells that may be present during medium changes and subcultures. Instead, spin them down using gentle centrifugation and add them back to the adherent population. The cells attach in small tightly formed clusters and some single cells. As the cells attach and start to proliferate and spread, they will grow as flattened epithelial-like islands of tightly packed cells.
