Function

The cell wall binding region, albumin binding region and other non-specific binding regions have been eliminated from this protein to ensure the maximum specific IgG binding. The 6x His-tag can be used for affinity purification or for Protein A detection using anti-His-tag antibody. The recombinant Protein A is ideal for purification of polyclonal or monoclonal IgG antibodies.

Protein A binds to most human and mouse IgG subclasses (e.g: human IgG1, IgG2, IgG4; mouse IgG1, IgG2a, IgG2b, IgG3).

It also binds to total IgG from cow, guinea pig, hamster, horse, pig, and rabbit.
Protein A has little affinity to chicken, goat, rat and sheep.


This product is manufactured by BioVision, an Abcam company and was previously called 6500 Protein A (Liquid form). 6500-10 is the same size as the 10 mg size of ab52953.

일반 정보

기능

Plays a role in the inhibition of the host innate and adaptive immune responses. Possesses five immunoglobulin-binding domains that capture both the fragment crystallizable region (Fc region) and the Fab region (part of Ig that identifies antigen) of immunoglobulins (PubMed : 10805799, PubMed : 2938951, PubMed : 4163007). In turn, Staphylococcus aureus is protected from phagocytic killing via inhibition of Ig Fc region. In addition, the host elicited B-cell response is prevented due to a decrease of antibody-secreting cell proliferation that enter the bone marrow, thereby decreasing long-term antibody production. Inhibits osteogenesis by preventing osteoblast proliferation and expression of alkaline phosphatase, type I collagen, osteopontin and osteocalcin. Acts directly as a pro-inflammatory factor in the lung through its ability to bind and activate tumor necrosis factor alpha receptor 1/TNFRSF1A (By similarity).
