    Synthetic peptide corresponding to the the Kallikrein loop area of human Kallikrein 1. (Peptide available as ab41419.)



Our Abpromise guarantee covers the use of ab28289 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB 1/1000 - 1/5000. Predicted molecular weight: 28 kDa.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
ICC/IF Use at an assay dependent concentration.


  • 功能Glandular kallikreins cleave Met-Lys and Arg-Ser bonds in kininogen to release Lys-bradykinin.
  • 组织特异性Isoform 2 is expressed in pancreas, salivary glands, kidney, colon, prostate gland, testis, spleen and the colon adenocarcinoma cell line T84.
  • 序列相似性Belongs to the peptidase S1 family. Kallikrein subfamily.
    Contains 1 peptidase S1 domain.
  • 翻译后修饰The O-linked polysaccharides on Ser-93, Ser-104 and Ser-167 are probably the mucin type linked to GalNAc. In PubMed:3163150, GalNAc was detected with the corresponding peptides but not located.

    Lane 2 : Kalikrein 1 at 0.01 µg
    Lane 3 : Kalikrein 1 at 0.001 µg

    Predicted band size : 28 kDa
    Observed band size : 38 kDa (why is the actual band size different from the predicted?)
  • IHC image of ab28289 staining in human normal pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with EDTA (pH9, epitope retrieval solution 2) for 20 mins. The section was then incubated with ab28289, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
