The AlphaLISA immunoassay kit for detection and quantitation of mouse IgA in cell culture/non-mouse serum allows for fast, reproducible, and sensitive detection without the need for time-consuming wash steps or complicated assay development.
For research use only. Not for use in diagnostic procedures.
There are five classes of mammalian immunoglobulins: IgA, IgD, IgE, IgM, and IgG. IgG is the most abundant immunoglobulin and is equally distributed in blood and tissue. In mice, the IgG class is further divided into four subclasses: IgG1, IgG2a/ IgG2c (strain specific), IgG2b, and IgG3. 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. IgG is involved in response to a foreign antigen. IgA is the main Ig in mucosal tissue and is believed to be involved in defense against viral and bacterial infections in these locations. Typically mouse serum and plasma samples contain about 0.075 to 0.45 mg/ml of IgA depending on the age and strain of mice. The present kit permits detection of mouse IgA (i.e. analyte) in different sample matrices, including different cell culture media.
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
