AlphaA Crystallin/CRYAA Antibody [Unconjugated]

Western blot shows lysates of mouse eye lens tissue. PVDF membrane was probed with 0.1 µg/mL Goat Anti-Human/Mouse AlphaA Crystallin/CRYAA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4848) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). For additional reference, recombinant human CRYAA and CRYAB (5 ng/lane) were included. Bands for AlphaA Crystallin/CRYAA were detected at approximately 20 - 23 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Simple Western lane view shows lysates of mouse eye lens tissue, loaded at 0.2 mg/mL. A specific band was detected for AlphaA Crystallin/CRYAA at approximately 28 kDa (as indicated) using 1 µg/mL of Goat Anti-Human/Mouse AlphaA Crystallin/CRYAA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4848) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the12-230 kDa separation system.

Background

AlphaA Crystallin (CRYAA, also known as Crystallin alpha -A chain and HspB4) is a 21‑22 kDa member of the HSP20 family of proteins. It is found in lens epithelium where it noncovalently oligomerizes with CRY-alpha B to generate a transparent 350‑1000 kDa alpha -Crystallin protein complex. Human CRYAA is 173 amino acids (aa) in length. There is a alpha -Crystallin Hsp domain over aa 63‑145. Multiple posttranslational modifications may exist. The C-terminal Ser and the N-terminal MetAspVal is occasionally cleaved. There is also phosphorylation at Ser45 and 122, O-linked GlcNAc modification at Ser162, deamidation at Asn101, and acetylation at Lys70. Full‑length human CRYAA is 54% aa identical to CRY-AlphaB, and 95% aa identical to mouse CRYAA.
