Description

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.
Western Blot analysis: 0.05 µg/mL of this antibody detected Alpha-crystallin B chain in 10 µg of human kidney and calf kidney tissue lysate.
