Antigen/Purification: ExpandCollapse

The antigen is a recombinant construct containing the seventh, eighth and ninth repeats of human alpha II spectrin expressed in and purified from E. Coli.

The antibody is Protein G purified from culture supernatant.

Biological Significance: ExpandCollapse

The spectrin family of cytoskeletal proteins is comprised of 2 alpha genes (?1 and ?2) and five beta genes (?1-?5). Spectrins have been shown to function as scaffolding proteins in mechanical support of the plasma membrane as well as bind other membrane proteins and lipids (Bennett and Baines 2001). Defects in spectrin genes have been linked to some forms of hereditary spherocytosis, a type of auto-hemolytic anemia which is characterized by spherical red blood cells that are more prone to lysis (Eber and Lux 2004).

100 µl in PBS + 50% glycerol + 5 mM sodium azide. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
