Description: | Protein G is a bacterial cell wall protein expressed at the cell surface of certain group C and group G Streptococcal strains. Protein G was found to be a powerful reagent for the detection of IgG, and consequently the antigen against which these antibodies are directed. It was used in Western blot analyses to detect various antigen-antibody complexes on nitrocellulose membranes. Moreover, protein G is widely used as a ligand coupled to resins in affinity chromatography for antibody purification. |
Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
