  • FunctionMay contribute to the transparency and refractive index of the lens.
  • Tissue specificityLens as well as other tissues.
  • Involvement in diseaseDefects in CRYAB are the cause of myofibrillar alpha-B crystallin-related (MFM-CRYAB) [MIM:608810]. A neuromuscular disorder that results in weakness of the proximal and distal limb muscles, weakness of the neck, velopharynx and trunk muscles, hypetrophic cardiomyopathy, and cataract in a subset of patients.
  • Sequence similaritiesBelongs to the small heat shock protein (HSP20) family.
  • Cellular localizationCytoplasm. Nucleus. Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles.

  • Immunohistochemical analysis of human heart tissue using ab13496 at the concentration 10ug/ml.

  • Immunohistochemical analysis of murine skeletal muscle tissue, staining Alpha B Crystallin with ab13496. Sections were blocked for 1 hour in 1% BSA and 10% FCS. The primary antibody was conjugated to AlexaFluor®594 before diluting 1/20 and incubating overnight at 4°C.
  • Overlay histogram showing SH-SY5Y cells stained with ab13496 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab13496, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

  • Predicted band size : 21 kDa
  • ab13496 staining Alpha B Crystallin in mouse brain tissue by Immunohistochemistry (free floating sections). Samples were incubated with the primary antibody at a 1/500 dilution for 16 hours at 4°C. A goat anti-mouse IgG conjugated to Alexa Fluor®594 was used as secondary antibody at a 1/10000 dilution.
