Sandwich ELISA - Protein A ELISA Kit (AB215542)

Interpolated concentrations of Protein A in Rabbit Monoclonal Antibody Protein A purified sample based on a 100 μg/mL antibody load.

The concentrations of Protein A were measured in duplicate and interpolated from the Protein A standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Protein A concentration was determined to be 442 pg/mL in the Rabbit Monoclonal Antibody sample.

제품 세부 정보

Protein A ELISA Kit (ab215542) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Protein A protein in cell culture supernatant. It uses our proprietary SimpleStep ELISA® technology. Quantitate Protein A with 3.7 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Protein A (Staphylococcus aureus Protein A) is a 42 kDa protein that is characterized by its ability to bind the Fc portion of immunoglobulins.

타겟 정보

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).
