Fig. 1From: Studies on the purification of polypeptide from sika antler plate and activities of antitumorPurity identification and molecular mass detection of the monomeric peptide. a Mass of the monomeric peptide was determined by Bruker micOTOF OllQ TOF with an experimental accuracy of ± 0.1 %, the peak is due to solvent interference. The molecular mass of this novel polypeptide was 10646 Da. b Purity identification of the monomeric peptide by utilizing the HPLC, The purity of this novel polypeptide was 91.2 %Back to article page
