Description
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).

Products Data 

 

A. Western blot analysis on (A) fetal heart and (B) rat eyeball lysates using anti-Alpha B Crystallin RabMAb (cat. # 2523-1), dilution (A) 1:5000 and (B) 1:20,000. 
B. Immunohistochemical analysis of paraffin-embedded human heart muscle using anti-Alpha B Crystallin RabMAb (cat. #2523-1).

Specificity
A synthetic peptide corresponding to residues on the C terminus of human Alpha B Crystallin was used as an immunogen.
