Scientific Data Images for Human Cystatin E/M Antibody
Detection of Human Cystatin E/M by Western Blot.
Western blot shows lysates of human skin tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Cystatin E/M Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1286) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Cystatin E/M at approximately 13 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Cystatin E/M by Simple WesternTM.
Simple Western lane view shows lysates of human skin tissue, loaded at 0.2 mg/mL. A specific band was detected for Cystatin E/M at approximately 13 kDa (as indicated) using 50 µg/mL of Goat Anti-Human Cystatin E/M Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1286) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.Applications for Human Cystatin E/M Antibody

Background: Cystatin E/M
Cystatin E/M encoded by the CST6 gene is a member of family 2 of the cystatin superfamily (1, 2). It inhibits papain and cathepsin B, two of the cysteine proteases. Its mRNA was found in many tissues by the two groups who did initial cloning (1, 2). However, its protein was found only in skin and sweat glands by a third group (3). In addition to being a cysteine protease inhibitor, cystatin E/M is also a substrate for transglutaminases (3). It is required for viability and for correct formation of cornified layers in the epidermis and hair follicles, as ichq mice, with a null mutation in the cystatin E/M gene, have defects in epidermal cornification and die between 5 and 12 days of age (4). Cystatin E/M expression and function may not be limited to cutaneous epithelia. For example, it is found in rat brain and is induced during neuronal cell differentiation (5).
