CHO INSR 1284 is a cell line that was isolated in 2008 from the ovary of a female Chinese hamster. Flp-In Cells (CHO-K1) cells were transfected with the gene for human insulin recepor B (M10051, NCBI GenBank), inserted in the basic vector pCDNA5-FRT-TO (cat.V6520-20 from Invitrogen) These cells can be used to investigate metabolic and mitogenic signaling of insulin metabolism and its metabolites. This cell line was deposited by S Ruggeber.
