アプリケーション Abreviews 特記事項
IHC-Fr 1/25 - 1/50. ABC method.
IHC-P 1/25 - 1/50. ABC method.
Sandwich ELISA Use at an assay dependent concentration. Can be paired for Sandwich ELISA with Mouse monoclonal to alpha 1 Antichymotrypsin (ab54693).

For sandwich ELISA, use this antibody as Detection at an assay dependent concentration with Mouse monoclonal to alpha 1 Antichymotrypsin (ab54693) as Capture.

WB Use at an assay dependent concentration. Detects a band of approximately 70 kDa (predicted molecular weight: 48 kDa).

Assay Dependent


  • 機能Although its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2.
  • 組織特異性Plasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains.
  • 関連疾患Defects in SERPINA3 may be a cause of chronic obstructive pulmonary disease (COPD) [MIM:107280].
  • 配列類似性Belongs to the serpin family.
  • ドメインThe reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.

    Predicted band size : 48 kDa
    Observed band size : 70 kDa (why is the actual band size different from the predicted?)
  • Human normal skin. Staining is mainly membrane-bound and cytoplasmic. Left panel: with primary antibody at 2 ug/ml. Right panel: negative 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 AR buffers citrate EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for rabbit 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.
