Detection of Human/Mouse AlphaA Crystallin/CRYAA by Western Blot.
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.
Detection of Mouse AlphaA Crystallin/CRYAA by Simple WesternTM.
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 the 12-230 kDa separation system.

Background: AlphaA Crystallin/CRYAA
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.
