There are a number of ELISA Kits available for the measurement of chromosome 19 open reading frame 80, another term for the human protein, angiopoietin like 8. Other synonyms may include: angiopoietin-like protein 8, betatrophin variant 1, betatrophin variant 2, hepatocellular carcinoma-associated gene TD26, lipasin, refeeding-induced fat and liver protein, and C19orf80. It is encoded by the ANGPTL8 gene to yield a protein 198 amino acids in length and 22.1 kDa in size. The protein is categorized into the ANGPTL8 family. Versions of chromosome 19 open reading frame 80 are present in other organisms, including: Mouse, Rat.
