Protein A/G Spin Kit (0.2 mL) (VS-0824-WK16)
CAT#: VS-0824-WK16
This protein A/G spin kit is convenient for rapid, small-scale affinity purification of antibodies from a variety of sample types. Each pre-filled microcentrifuge spin column of the immobilized protein resin enables quick purification of ≥ 1.4mg human IgG from serum or other sample. The actual amount of IgG purified varies depending on the sample type and the specific spin column used. Also included in each kit are sufficient collection tubes, buffers and a streamlined protocol for purifying at least 10 antibody samples.

- Background
- Protein A/G is a genetically-engineered protein that combines the IgG binding domains of both Protein A and Protein G. The fusion protein is expressed in E. coli. Protein A/G contains four Fc binding domains from Protein A and two from Protein G, resulting in a final mass of 50,460 daltons. Protein A/G is not as pH-dependent as Protein A alone, but otherwise has the additive properties of Protein A and G.
