General description
Alpha B-crystallin is a major structural protein in the vertebrate eye lens, but is also found in cardiac and skeletal muscles, kidney, and brain. Alpha B-crystallin is also found to be a component of Rosenthal fibers and a consistent tissue marker of epileptic foci. It occurs as large aggregates of up to 106 Da, composed of two proteins, αA- and αB-crystallin. The αA gene encodes a polypeptide of 173 residues, while αB-crystallin gene encodes a 175 residue polypeptide. αB-crystallin, like the small heat shock proteins (sHsp′s), is induced by heat or osmotic shock and is upregulated by stress. α-crystallin and the sHsp′s protect other proteins from heat-induced aggregation. The two other crystallin families, β and ɣ, are homologous to each other but not to the α-family or the sHsp′s.
Specificity
This antibody recognizes the N-terminus of alpha B-crystallin.
Immunogen
Epitope: N-terminus
KLH-conjugated linear peptide corresponding to the N-terminus human alpha B-crystallin.
Application
Immunohistochemistry Analysis: A 1:1,000 dilution from a representative lot detected Alpha-crystallin B chain in rat lens fiber tissue. A 1:2,000 dilution from a representative lot detected Alpha-crystallin B chain in strong rat lens fiber tissue (data not provided). A 1:1,000 dilution from a representative lot detected Alpha-crystallin B chain in strong muscle fiber tissue (data also not provided). It is recommended to use a 1:2,000 dilution only for strong rat lens fiber tissue.

Proteins in the eye lens have negligible turnover and therefore progressively accumulate chemical modifications during aging. Carbonyls and oxidative stresses, which are intricately linked to one another, predominantly drive such modifications. Oxidative stress leads to the loss of glutathione (GSH)

Acetylation of lysine residues occurs in lens proteins. Previous studies have shown an improvement in the chaperone activity of αA-crystallin upon acetylation. Sirtuins are NAD+-dependent enzymes that can deacylate proteins. The roles of sirtuins in regulating the acetylation of lens

Lens proteins become increasingly cross-linked through nondisulfide linkages during aging and cataract formation. One mechanism that has been implicated in this cross-linking is glycation through formation of advanced glycation end products (AGEs). Here, we found an age-associated increase in stiffness
