Which is the molecular weight of the protein angiogenin?
['Angiogenin is a potent blood-vessel-inducing polypeptide with a molecular weight of 14,000 that has a unique ribonucleolytic activity.', ' Bovine angiogenin is a single-chain protein of 125 amino acids; it contains six cysteines and has a calculated molecular weight of 14,595.', 'The amino acid composition of this basic (isoelectric point greater than 9.5), single-chain protein of molecular weight approximately 14 400 has been determined.', 'was found to have a molecular weight of 15 kDa on SDS-PAGE, and the sequence of the N-terminal 25 amino acid residues was identical to that of bovine angiogenin', 'Human angiogenin is a 14-kDa plasma protein with angiogenic and ribonucleolytic activities. ', ' angiogenin-1 (15 kDa). ', 'This protein is 14 kD in molecular weight, and is identical to the angioplastic factor angiogenin. ', ' angiogenin (M(r) = 14,120),']
['The molecular weight of angiogenin is 14,120 Da. The bovine angiogenin is 14,595 Da']
['14,120 Da']
