In recent patent filings and research papers, C4 Zip-tips have been critical for identifying protein isoforms and calculating theoretical masses within 0.5 Da of their primary amino acid sequences. By removing buffers and exchange salts, researchers can achieve the high-resolution mass spectra required for modern drug development and biological research. CN101883788A - 多肽，抗体可变结构域&拮抗剂
