| Biochem/physiol Actions: | First spontaneously immortalized prostate cancer cell line to be established from a trans-rectal needle biopsy (TRBP) of a patient with castration-resistant prostate cancer (CRPC). Bob is a novel pre-clinical model for functional studies in CRPC and especially for studying the CRPC "basal" phenotype. This cell line is cultured in serum-free culture medium, a derivative of Bob is also available i.e. SerBob, Sigma Catalogue number 10021101, which has been adapted to medium containing serum. SerBob is more differentiated and invasive than Bob. The Y chromosome could not be detected in this cell line by short tandem repeat (STR)-PCR analysis when tested at ECACC. It is a known phenomenon that due to the increased genetic instability of cancer cell lines the Y chromosome can be rearranged or lost resulting in lack of detection. The cell line is identical to the source provided by the depositor based on the STR-PCR analysis. |

| Preparation Note: | Keratinocyte-SFM supplied with prequalified human recombinant epidermal growth factor 1-53 (EGF 1-53), bovine pituitary extract (BPE) and glutamine) + 2ng/ml leukaemia inhibitory factor, 2ng/ml stem cell factor + 100ng/ml cholera toxin + 1ng/ml granulocyte macrophage colony stimulating factor. |
| Preparation Note: | Split sub-confluent cultures (70-80%) 1:5 to 1:20 i.e. seeding at 2-4 x 104 cells/cm2 using 0.25% trypsin or trypsin/EDTA; 5% CO2; 37°C. Cells must be centrifuged at 400 x g for 5 minutes to remove the trypsin at each subculture. Cells are cryopreserved in 45% conditioned media: 45% fresh media: 10% DMSO. At confluence 5-7 x 104 cells/cm2 can be expected. |
