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.
It is a mouse fusion cell line derived from Sp2/0 cells that had been transfected with high-titer L6PNL recombinant retrovirus carrying a mouse interleukin-6 (IL-6) cDNA under the transcriptional control of the viral LTR and the neo gene encoding bacterial neomycin phosphotransferase (G418 resistance).
Sp2/IL-6 cells secrete IL-6 and are an improved myeloma fusion parent in terms of both the relative number of viable B cell hybridomas producing immunoglobulin and the proportion of hybridomas producing antigen-specific monoclonal antibodies.
