There are a number of ELISA Kits available for the measurement of tachykinin 2, another term for the human protein, tachykinin precursor 3. Other synonyms may include: tachykinin-3, gamma tachykinin 3, neurokinin b, neuromedin K, tachykinin 3, HH10, and NK3. It is encoded by the TAC3 gene to yield a protein 121 amino acids in length and 13.4 kDa in size. However, there are up to 3 reported isoforms. The protein is categorized into the Tachykinin family. Versions of tachykinin 2 are present in other organisms, including: Mouse, Rat, Frog, Chicken.
