  • ターゲット情報

    • 機能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.
    • 組織特異性Secreted in plasma.
    • 配列類似性Belongs to the protease inhibitor I39 (alpha-2-macroglobulin) family.
    • 発生段階Contrary to the rat protein, which is an acute phase protein, this protein is always present at high levels in circulation.
    • 細胞内局在Secreted.

    • Ab58703 staining alpha 2 Macroglobulin in human liver.
      Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
      Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 antigen retrieval buffers EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
    • ab58703 staining alpha 2 Macroglobulin in rat decidual cells by Immunocytochemistry. Cells were fixed with Methanol, permeabilized with PBS, 5% BSA, 0.1% Triton X-100 and 0.2% Tween-20 and blocking with 5% BSA was performed for 15 minutes at RT. Samples were incubated with primary antibody (1/500) in PBS for 14 hours at 4°C. A commercially available Avidin–biotin alkaline phosphatase complex technique was used.
