Anti-Involucrin [SY5] mAb

Tool Details

*FOR RESEARCH USE ONLY

• Name: Anti-Involucrin [SY5] mAb
• Alternate name: Anti-Involucrin; involucrin antibody
• Clone: SY5
• Tool sub type: Primary antibody
• Class: Monoclonal
• Conjugation: Unconjugated
• Molecular weight: 66-170 kDa
• Strain: Balb/c
• Reactivity: Dog ; Human ; Pig ; Primate
• Host: Mouse
• Application: IF ; FACS ; IHC ; IF ; IP ; WB
• Description: Clone SY5 recognises a protein of 66kDa-170kDa, identified as involucrin. Involucrin is a protein precursor of the epidermal cornified envelope and a differentiation marker of human keratinocytes. Involucrin expression is altered in pathological conditions such as psoriasis and other benign epidermal hyperplasias. This mAb stains the involucrin in a variety of sizes: 170kDa in MCF-7 cells, 66kDa in dog, and a doublet of 105kDa in pig. It's epitope maps between codon 421-568 of human involucrin. SY5 is useful for studies of changes in involucrin expression in pathological studies.
• Immunogen: Purified involucrin from human keratinocytes.
• Isotype: IgG1 kappa
• Myeloma used: P3X63Ag8
• Recommended controls: MCF-7 cells. Localized to upper spinous and granular layers in normal skin.

Target Details

• Target: Involucrin
• Molecular weight: 66-170 kDa
• Tissue cell line specificity: MCF-7 cells. Localized to upper spinous and granular layers in normal skin.
• Target background: In Western blotting of cultured human keratinocytes, this MAb reacts with a 120kDa protein. It stains the involucrin in a variety of sizes: 170kDa in MCF-7 cells, a doublet of ~115kDa and 150kDa in gorilla and owl monkey, 66kDa in dog, and a doublet of 105kDa in pig. Its epitope maps between codon 421-568 of human involucrin. 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 is a protein precursor of the epidermal cornified envelope and a differentiation marker of human keratinocytes. SY5 is useful for studies of changes in involucrin expression in pathological studies. 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.
