Description

Store vial at 4C prior to restoration. For extended storage aliquot contents and freeze at -20C or below. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

This antibody is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Peroxidase, anti-Goat Serum as well as purified and partially purified a2-Macroglobulin [Human Plasma]

alpha 2-Macroglobulin Antibody [HRP]

Goat anti Alpha-2-Macroglobulin antibody ( lot 20172) was used to detect Alpha-2-Macroglobulin under reducing (R) and non-reducing (NR) conditions. Reduced samples of purified target proteins contained 4% BME and were boiled for 5 minutes. Samples of ~1ug of protein per lane were run by SDS-PAGE. Protein was transferred to nitrocellulose and probed with 1:3000 dilution of primary antibody (ON 4 C in ). Detection shown was using Dylight 649 conjugated Donkey anti goat ( lot 20834 1:10K in TBS/) 1 hr RT. Images were collected using the BioRad VersaDoc System.

Background: alpha 2-Macroglobulin

Alpha 2 macroglobulin is a serum protein which is mainly synthesised in the liver. It functions as a broad range irreversible proteinase inhibitor that forms a "trap" around most proteases. Alpha 2 macroglobulin is a tetrameric molecule, and with a molecular weight of 720 kDa, it so large a molecule that it tends to remain intravascular. Following conformational change the proteinase is deposited within a central cavity where it is still active but prevented from further contact with its substrate. Removal of the complex is mediated by the generation of recognition sites which react with receptors on a variety of cells including macrophages and liver cells. Alpha 2 macroglobulin is localized on the surface of peripheral blood lymphocytes.
