General description

Non-erythroid Spectrin, also known as Fodrin, plays a role in stabilizing membrane structures, maintaining cell shape and linking the cytoskeleton to plasma membranes or intracellular vesicles. As one of the primary targets cleaved by activated caspases during apoptosis, the full-length ~240 kDa protein can be cleaved to yield an N-terminal product of ~150 kDa, and C-terminal products of ~120 and ~35 kDa.


Specific for the 240, 150, and 120 kDa forms of alpha-spectrin/alpha-fodrin molecule of all mammalian nonerythroid cells and chicken alpha-spectrin.

Wide-mammalian reactivity is expected.


Chicken red blood cell membranes purified by hypotonic lysis and mechanical enucleation.


Immunohistochemistry (IFA):
A 1:200-1:400 dilution of a previous lot was used in immunohistochemistry.
Does not work on paraffin sections.

Optimal working dilutions must be determined by end user.

Chromatin Immunopreciptiation:
A previous lot of this antibody was used to immunoprecipitate Spectrin Alpha from chromatin-associated protein extracts derived from normal human, HeLa, FA-A, and transduced FA-A cells (McMahon, L.W., et al. (1999). J. Biological Chem. 274:32904-32908).
