|Application ||WB, IHC|
|Calculated MW||20159 Da|
|Other Names||Alpha-crystallin B chain, Alpha(B)-crystallin, Heat shock protein beta-5, HspB5, Renal carcinoma antigen NY-REN-27, Rosenthal fiber component, CRYAB, CRYA2|
|Target/Specificity||A synthetic peptide corresponding to residues on the C terminus of human Alpha B Crystallin was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Crystallin Alpha B Antibody Crystallin is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||May contribute to the transparency and refractive index of the lens. Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions.|
|Cellular Location||Cytoplasm. Nucleus. Note=Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles (PubMed:19464326) Localizes at the Z-bands and the intercalated disk in cardiomyocytes (PubMed:28493373).|
|Tissue Location||Lens as well as other tissues (PubMed:838078, PubMed:2387586). Expressed in myocardial tissue (PubMed:28493373)|

Alpha B Crystallin, first identified as a structural component of the vertebrate eye lens, is expressed at high levels in lens and at lower levels in a number of other tissues, most notably cardiac and skeletal muscle, kidney, and brain (1). It is a major protein component of Rosenthal fibers, which massively accumulate in the brains of patients suffering from Alexander's disease (2). The major phosphorylation site of Alpha B Crystallin in brains of patients with Alexander's disease or Alzheimer's disease as well as in aged controls is Serine 59 (3). Racemization, isomerization, and oxidation of Alpha B Crystallin are said to occur spontaneously in the aging process (4).
