| titleOfInvention | IgM purification method |
| abstract | The present invention relates to the technical field of antibodies, in particular, to a method for purifying IgM, comprising: a. providing a sample containing IgM; b. obtaining a protein precipitate through at least one protein precipitation treatment and at least one protein concentration treatment; c. The protein precipitate is redissolved, and the impurity protein is removed by the octanoic acid-ammonium sulfate method to obtain a crude extract comprising the IgM; d. processed by hydrophobic chromatography to collect the permeate; e. by hydroxyphosphate limestone chromatography, Collect the eluate; and f. Purify the IgG-capture affinity chromatography resin and collect the permeate. The purity of IgM in the composition purified by the above method of the present invention is more than 95%, and the product is stable, precipitation is not easy to occur after cryopreservation, and the antibody activity is good. |
