It recognizes a protein of 66kDa-170kDa, identified as involucrin. In Weste blotting of cultured human keratinocytes, this mAb reacts with a 120kDa protein. Involucrin is expressed in a range of stratified squamous epithelia, including the coea, which lacks a distinct coified layer. In normal epidermis, it is first expressed in the upper spinous layers, and in keratinocyte cultures, all cells that have left the basal layer express it. Involucrin expression is altered in pathological conditions: in psoriasis and other benign epidermal hyperplasias, involucrin expression begins closer to the basal layer than normal; expression is abnormal in squamous cell carcinomas and premalignant lesions, and is reduced in severe dysplasias of the larynx and cervix.
Formulation
1 mg/ml in 1X PBS; BSA free, sodium azide free
Host
Mouse
Immunogen Region
Purified involucrin from human keratinocytes was used as the immunogen for the Involucrin antibody.
Isotype
Mouse IgG1, kappa
Species Reactivity
Human
Note
Optimal dilution of the Involucrin antibody should be determined by the researcher.1. Staining of formalin-fixed tissues is enhanced by digestion with Trypsin or Protease XXV at 1mg/ml PBS for 5 min at 37oC. Enzyme digestion is more effective than Citrate buffer based epitope unmasking.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
