Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 143 kDa (predicted molecular weight: 69 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Relevance

      CD42b is a platelet activation marker involved in the process of coagulation as an aggregating factor. It interacts with extracellular matrix as well as with adhesion molecules. Its expression and activation seems to be regulated by VEGF and PDGF.

    • ab134087 staining CD42b in human bone marrow tissue by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraffin and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/250. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at 1/500.

      Negative control 1: PBS in place of primary antibody.
