Anti-NFM (Neurofilament Medium Chain) Antibody

Cell Markers, Neuronal Markers, Axonal Markers

United States

150 kDa

Phosphate-buffered (10 mM) isotonic (0.9%, w/v) saline ("PBS" pH 7.2) with bovine serum albumin (BSA, 0.5%) added to prevent absorption to the plastic and sodium azide (0.02%, w/v) added as a preservative

NFM protein was purified from bovine spinal cords following the method of Delacourte et al. ["Study of the 10-nm-filament fraction isolated during the standard microtubule prepartion" (1980). Biochem. J. 191(2): 543-546], followed by Prepcell purification (Bio-Rad). Antibodies were prepared by injecting purified NFM protein into laying hens and purifying the IgY fraction from eggs collected from hyper-immunized hens. After several boosts, hens were co-boosted with recombinant NFM protein expressed in bacteria. These antibodies have been validated with human, mouse and rat tissues.

Human Neurofilament Medium Chain (NFM) is a 102, 448 dalton protein (916 amino acids) expressed in CNS and PNS neurons. This cytoskeletal protein is normally phosphorylated in vivo and its extent of phosphorylation correlates with different states of axonal growth and stabilization. These observations have led to the hypothesis that the NFM protein cross-links adjacent neurofilament strands and contributes to the structural integrity of the axon.
