Anti-Involucrin, clone IVRN/827

0.2 mg/ml with 0.1 mg/ml BSA (US sourced), 0.05% sodium azide. It 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. Protein function: Part of the insoluble cornified cell envelope (CE) of stratified squamous epithelia. [The UniProt Consortium]
