Technical Data
Spectrin alpha chain, erythrocyte (Spectrin, alpha, erythrocytic 1, EL2, Erythroid alpha-spectrin, HPP, HS3, Spectrin alpha chain, erythrocyte, SPH3, SPTA)
Spectrin is the predominant component of the membrane skeleton of the red blood cell and is essential in determining shape and deformability of the membrane. It consists of 2 nonidentical subunits, alpha (MW 240,000) and beta (MW 225,000). Spectrin is present in the red cell membrane in a tetrameric or possibly higher polymeric form through head to head self association of heterodimers that are linked by actin polymers and protein 4.1 to form a 2 dimensional network.

Suitable for use in Immunofluorescence, ELISA, Western Blot, and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunofluorescence: 1:100 -1:500
ELISA: 1:105-1:106
Western Blot: 1:102-1:103
Immunohistochemistry: 1:10-1:50
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
