This is the complete description of the cell line that you selected.
By clicking on a generic term (e.g., SPECIES) you will go to the corresponding index (e.g., index of species), while by clicking on a specific term (e.g., retinoblastoma) you will go to the list of corresponding cell lines (e.g., retionoblastoma cell lines).
SPECIES: mouse, C57BL
TISSUE/ORGAN: pre B cell
DSMZ catalog code: ACC 241
Morphology: cells are very small and grow mainly in small clusters, but also singly in suspension
Description: mouse pre B cells established from the bone marrow of a CBA/C57BL mouse in 1995 confirmed as mouse with IEF of AST, NP
Viruses: ELISA: reverse transcriptase negative
Depositor: Dr. A. R. Mire-Sluis, National Institute for Biological Standards and Control, Potters Bar, England
Available in the following LABORATORY:
German Collection of Microorganisms and Cell Cultures (DSMZ, Braunschweig)
