Rabbit anti Mouse alpha-2 macroglobulin

Cat. Num. AAA573728

• Gene Names: A2M; A2MD; CPAMD5; FWP007; S863-7
• Reactivity: Mouse
• Applications: Immunoprecipitation
• Synonyms: alpha-2 macroglobulin; Polyclonal Antibody; Rabbit anti Mouse alpha-2 macroglobulin; anti-A2M antibody

• Host: Rabbit
• Reactivity: Mouse
• Clonality: Polyclonal
• Specificity: Precipitating polyclonal Rabbit antiSerum to Mouse alpha-2 macroglobulin

• Applicable Applications for anti-A2M antibody: Immunoprecipitation (IP)
• Application Notes: Immunoprecipitation. In immunoelectrophoresis use 2 ul serum or equivalent against 120 ul antiserum. In double radial immunodiffusion use a rosette arrangement with 10 ul antiserum in 3 mm diameter center well and 2 ul serum samples (neat and serially diluted) in 2 mm diameter peripheral wells.
• Source: Alpha-2 macroglobulin ids the major protein in the alpha-2 region of mouse serum after separation by electrophoresis. It is a large polymer and a strong antigen. It forms about one-third in the total of the alpha-2 globulins. The protein is isolated by ammonium sulphate precipitation, ion exchange chromatography, gel filtration and preparative starch block electrophoresis. In the purification of alpha-2 macroglobulin the activation of kallikrein is avoided, since it forms an irreversible bond with aplpha-2 macroglobulin, thus contaminating the final immunogen. Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Product: Delipidated, heat inactivated, lyophilized, stable whole antiserum No preservative added Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal rabbit serum. No foreign proteins added.
• Reactivity Note: Inter-species cross reactivity is a normal feature of antibodies to Serum proteins, since homologous proteins of different species frequently share antigenic determinants. Cross-reactivity of this antiSerum has been tested in double radial immunodiffusion (Ouchterlony) with the following results: Bovine +/- ferret +/- Horse +/- Rat ++ Cat +/- Goat - Human -Sheep - Chicken - Guinea Pig +/- Monkey - Swine +/- Dog - Hamster + pigeon - Turkey -
• Preparation and Storage: The lyophilized antiserum is shipped at ambient temperature and may be stored at +4 degree C; prolonged storage at or below -20 degree C. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4 degree C, not refrozen, and preferably used the same day. Lyophilized at +4 degree C--at least 10 years. Reconstituted at or below -20 degree C--3-5 years. Reconstituted at +4 degree C--7 days

The reactivity of the antiserum is restricted to alpha-2 macroglobulin as tested in immunoelectrophoresis and radial immunodiffusion. A characteristic single precipitin line is obtained with normal serum which shows a reaction of identity with the precipitin line with purified alpha-2 macroglobulin. In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence alpha-2 macroglobulin in mouse serum or other body fluids and to determine its concentration. This antiserum is not intended for use in non-precipitating antibody-binding or other highly sensitive assays, but this does not exclude such use if proper controls are included.

NCBI Description

Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease (AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits. [provided by RefSeq, Jul 2008]

Uniprot Description

A2M: Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase. Belongs to the protease inhibitor I39 (alpha-2- macroglobulin) family.
