Technical Data
Crystallin, alpha B
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 (RF), 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).

Suitable for use in Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Western Blot: 1:500-2000
Immunohistochemistry: 1:100-250
Immunocytochemistry: 1:100-250
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
