Detection of Human, Mouse, and Rat AlphaB Crystallin/CRYAB antibody by Western Blot.

Detection of Human, Mouse, and Rat AlphaB Crystallin/CRYAB by Western Blot.

Western blot shows lysates of rat heart tissue, mouse heart tissue, and human heart tissue. PVDF membrane was probed with 0.1 µg/mL of Mouse Anti-Human/Mouse/Rat AlphaB Crystallin/CRYAB Monoclonal Antibody (Catalog # MAB4849) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human AlphaB Crystallin/CRYAB and recombinant human AlphaA Crystallin/CRYAA (5 ng/lane) were included. A specific band was detected for AlphaB Crystallin/CRYAB at approximately 23 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human AlphaB Crystallin/CRYAB antibody by Simple WesternTM.

Detection of Human AlphaB Crystallin/CRYAB by Simple WesternTM.

Simple Western lane view shows lysates of human heart tissue, loaded at 0.2 mg/mL. A specific band was detected for AlphaB Crystallin/CRYAB at approximately 28 kDa (as indicated) using 1 µg/mL of Mouse Anti-Human/Mouse/Rat AlphaB Crystallin/CRYAB Monoclonal Antibody (Catalog # MAB4849). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: AlphaB Crystallin/CRYAB

CRY-alpha B (crystalline alpha -B chain/CRYAB; also HspB5) is a 22-23 kDa member of the HSP20 family of proteins.  It has widespread expression, and is found in lens epithelium where it noncovalently oligomerizes with CRYAA to generate a transparent 350-1000 kDa alpha -crystalline protein complex.  Human CRYAB is 175 amino acids (aa) in length. It contains an alpha -crystalline Hsp domain over aa 66-149.  Multiple post-translational modifications may exist. The N-terminal Met and MetAspIleAlaIleHis sequence is occasionally cleaved.  It may also be phosphorylated at Ser45 and 59, be potentially O-GlcNAc modified at Thr158, 162 or 170, and acetylated at Lys92.  An alternate start site at Met68 may be accompanied by a 47 aa substitution for aa 109-175.  Full-length human CRYAB shares 54% aa sequence identity with CRYAA, and 98% aa identity with mouse CRYAB.
