There are a number of ELISA Kits available for the measurement of TGB1, another term for the human protein, pro-platelet basic protein. Other synonyms may include: platelet basic protein, C-X-C motif chemokine 7, CXC chemokine ligand 7, beta-thromboglobulin, connective tissue-activating peptide III, leukocyte-derived growth factor, and low-affinity platelet factor IV. It is encoded by the PPBP gene to yield a protein 128 amino acids in length and 13.9 kDa in size. The protein is categorized into the Intercrine alpha (chemokine CxC) family. Versions of TGB1 are present in other organisms, including: Mouse, Rat.
