Immunoassay of anti-hm1.24 antibody

摘要

A process whereby a highly purified soluble HM1.24 antigen protein can be produced at a high efficiency. Namely, a process for producing a soluble HM1.24 antigen extracellular domain characterized by comprising culturing animal cells transformed by an expression vector which contains an (A1)EF1a promoter and a gene encoding soluble HM1.24 antigen lacking the intracellular domain ligated downstream of the promoter, and isolating and purifying the soluble HM1.24 antigen from the culture.
