A rapid and simple affinity chromatography method for purifying IgM from
myeloma
serum and ascites fluid is described.
Complement protein
C1q is coupled to Sepharose with an efficiency of 35%, giving 1.7 mg of C1q bound/ml of gel. This C1q-Sepharose selectively binds IgM from crude samples at 5 degrees C, with a capacity of 0.4 mg of IgM/ml of gel. The bound IgM may be eluted simply and isocratically by bringing the gel to room temperature for 2 h, or by washing with buffer containing 0.5 M KI. The eluted IgM is highly pure by SDS-PAGE and double immunodiffusion analysis, although IgG may be a potential contaminant. The C1q-Sepharose is stable for at least 18 months.
