|Detection of Human ZAG by Western Blot. Western blot shows human plasma and lysates of human prostate tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human ZAG Monoclonal Antibody (Catalog # MAB4764) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for ZAG at approximately 41 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.|
|Detection of Human ZAG by Simple WesternTM. Simple Western lane view shows lysates of human prostate tissue, loaded at 0.2 mg/mL. A specific band was detected for ZAG at approximately 59 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human ZAG Monoclonal Antibody (Catalog # MAB4764). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.|
ZAG (zinc-alpha 2-glycoprotein; also ZA2G) is a 40 kDa, secreted member of the MHC class I family of proteins. It is produced by adipocytes and various epithelial cells that generate exocrine-type secretions. ZAG is reported to stimulate lipid breakdown and thus may play a role in lipid homeostasis. Mature human ZAG is 278 amino acids (aa) in length. It contains one MHC class I antigen region (aa 26‑201) and a C2‑type Ig‑like domain (aa 207‑292). Two alternate splice forms exist; one shows a 66 aa substitution for the C‑terminal 30 aa, and a second shows a nine Lys substitution for aa 151‑298. Mature human ZAG is 60% aa identical to mouse ZAG.
