Guinea Pig IgG ELISA Kit

製品の詳細

Guinea Pig IgG ELISA Kit (ab190813) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Pig IgG protein in serum and plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Guinea Pig IgG with 13 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.

There are four classes of immunoglobulins in Guinea Pig: IgM, IgE, IgD and IgG. IgG is the most abundant immunoglobulin and is equally distributed in blood and tissue. In Guinea Pig, the IgG class is further divided into two isotypes: IgG1 and IgG2. The general immunoglobulin structure is composed of four polypeptide chains, two heavy and two light chains linked together and to each other by disulfide bonds, creating a tetrameric quaternary structure. The resulting tetramer creates two identical halves which together form a Y like structure. While the amino-terminal portions that exhibits highly variable amino-acid composition are involved in antigen binding, the C terminal constant parts are involved in complement binding, placental passage and binding to cell membrane. IgG is involved in response to a foreign antigen. The presence of IgG usually signifies a mature antibody response. IgG has a molecular weight of about 150 kDa, it can bind to many pathogens and also plays an important role in antibody dependent cell-mediated cytotoxicity. Typically Guinea Pig serum and plasma samples contain about 7 to 10 mg/ml of IgG.
