Involucrin Antibody IVRN/827 / Mouse Monoclonal [clone IVRN/827] (V2647)

Description

Involucrin Antibody IVRN/827 recognizes a protein of 66kDa-170kDa, identified as involucrin. In Western blotting of cultured human keratinocytes, this mAb reacts with a 120kDa protein. Involucrin is expressed in a range of stratified squamous epithelia, including the cornea, which lacks a distinct cornified 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.

Application Notes

Optimal dilution of the Involucrin Antibody IVRN/827 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.

Immunogen

Purified involucrin from human keratinocytes was used as the immunogen for the Involucrin Antibody IVRN/827.

Storage

Store the Involucrin Antibody IVRN/827 at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
