Magnetic Protein A and G Antibody Purification

High-yield, robust purification of antibodies from serum, ascites and cell media.

(Note: Magne® Protein G and Magne® Protein A Beads are not recommended for use in immunoprecipitation (IP) or co-IP applications.)

Antibody Purified from Various Sample Types using the Magne® Protein A and Magne® Protein G Beads.

11208TA-W
Antibody was purified from 50μl of cell culture media (mouse IgG1), mouse ascites (IgG2a) and goat serum with 50μl of Magne® Protein A Beads (A) and Magne® Protein G Beads (G) using published protocols (Technical Manual #TM371). Samples were separated via SDS-PAGE by adding 1μl of starting material (SM) or 5μl of purified sample (A or G) and stained with Coomassie®-based stain
