K6H6/B5

Mouse x Human hybrid myeloma. Derived by a fusion of P3/NSI/1-Ag4-1 myeloma cells with cells from a human nodular lymphoma. The cells are HPRT- and do not secrete immunoglobulin. They are used as a fusion partner for human B lymphocytes. The cells are deficient in hypoxanthine phosphoribosyltransferase (HPRT) and are excellent fusion partners for human B cells. Tested and found negative for ectromelia virus (mousepox).
