Ready-to-use ELISA kits are available for the detection of N-ethylmaleimide sensitive factor, an alias of the protein, N-ethylmaleimide sensitive factor, vesicle fusing ATPase. The official gene symbol is NSF. The protein, with a mass of 82.6 kDa and length of 744 residues, is reported to be cytoplasmic. It is a member of the AAA ATPase family and may be known by other names, including: SKD2, SEC18, NEM-sensitive fusion protein, N-ethylmaleimide-sensitive fusion protein, N-ethylmaleimide-sensitive factor-like protein, and vesicle-fusing ATPase.
