Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 31 kDa (predicted molecular weight: 39 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Inter-alpha-trypsin inhibitor inhibits trypsin, plasmin, and lysosomal granulocytic elastase. Inhibits calcium oxalate crystallization.
      Trypstatin is a trypsin inhibitor.
    • Tissue specificity

      Expressed by the liver and secreted in plasma. Alpha-1-microglobulin occurs in many physiological fluids including plasma, urine, and cerebrospinal fluid. Inter-alpha-trypsin inhibitor is present in plasma and urine.
    • Sequence similarities

      In the N-terminal section; belongs to the calycin superfamily. Lipocalin family.
      Contains 2 BPTI/Kunitz inhibitor domains.
    • Post-translational

      The precursor is proteolytically processed into separately functioning proteins.
      3-hydroxykynurenine, an oxidized tryptophan metabolite that is common in biological fluids, reacts with Cys-53, Lys-111, Lys-137, and Lys-149 to form heterogeneous polycyclic chromophores including hydroxanthommatin. The reaction by alpha-1-microglobulin is autocatalytic; the human protein forms chromophore even when expressed in insect and bacterial cells. The chromophore can react with accessible cysteines forming non-reducible thioether cross-links with other molecules of alpha-1-microglobulin or with other proteins such as Ig alpha-1 chain C region 'Cys-352'.
      Heavy chains are interlinked with bikunin via a chondroitin 4-sulfate bridge to the their C-terminal aspartate.
      Addition of glycosaminoglycan chondroitin sulfate, allows cross-linking between the different components.
