General description

Genetically engineered truncated protein G; retains affinity for IgG, but lacks albumin and Fab binding sites and membrane-binding regions.
Protein G, a cell wall protein,[1] is obtained from group G streptococci.[2] The extracellular part of this protein is made of two/three small domains or serum albumin binding (GA domains) and two/three immunoglobulin (IgG) binding domains (B domains).[1]

Application

Protein G′ from Streptococcus sp. has been used in in vitro actin labeling assay.[3]

Biochem/physiol Actions

Protein G can bind all the human and mouse IgG subclasses.[2] It can bind to both the fragment crystallizable (Fc) and antigen-binding fragment (Fab) components of the antibody.[1]

Physical form

lyophilized powder in a Tris-HCl buffer, pH 7.5

Storage Class

11 - Combustible Solids
