There are a number of ELISA Kits available for the measurement of HGFIN, another term for the human protein, glycoprotein nmb. Other synonyms may include: glycoprotein (transmembrane) nmb, glycoprotein nmb-like protein, glycoprotein nonmetastatic melanoma protein B, hematopoietic growth factor inducible neurokinin-1 type, and osteoactivin. It is encoded by the GPNMB gene to yield a protein 572 amino acids in length and 63.9 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the PMEL/NMB family. Versions of HGFIN are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
