    Overview

    • Product name

      Proteinase K Antigen Retrieval Solution
    • Tested applications

      Suitable for: IHC-P, In situ hybridizationmore details
    • General notes

      ab64220 is a single-component, ready-to-use proteinase K solution for use in protease-induced antigen retrieval during IHC (PIER) and pre-treatment for in situ hybridization.
       

       

      Staining Protocol:

      1. IHC procedure: Incubate tissue section for 5 to 7 minutes at room temperature; Rinse and proceed with immunostaining.
      2. General ISH procedure: Incubate tissue section for 15 minutes at 37oC; Rinse and proceed with hybridization.

      Other products for IHC

      Other enzymes for antigen retrieval include: Pepsin Solution ab64201 and Trypsin Antigen Retrieval Kit ab259256.

      Proteinase K is an endolytic protease that cleaves peptide bonds preferentially next to the carboxyl group of N-substituted hydrophobic aliphatic and aromatic amino acids. Proteinase K is classified as a serine protease and exhibits broad substrate specificity. It can hydrolyze keratin; hence the name. Proteinase K is used for the digestion of proteins on tissue sections as a pre-treatment to aid in the preparation of mRNA and its detection by in situ hybridisation methods using oligonucleotide probes.
    • Alternative names

      • Endopeptidase K
      • Tritirachium alkaline proteinase
