It has been widely used as a hemostatic with rapidly growing marketing due to its advantage of localized clotting fibrinogen other than systemic coagulation. However, svTLEs from different species have various structures, functions, and hemostatic mechanisms. To ensure the efficacy and safety of Hemocoagulase <jats:italic>Agkistrodon halys pallas<\/jats:italic>, an exclusive and sensitive method has been developed to identify specific marker peptides based on liquid chromatography-tandem mass spectrometry with multiple reaction monitoring (LC-MS\/MS-MRM) mode. By combining transcriptomics and proteomics, a series of species-specific peptides of <jats:italic>Agkistrodon halys pallas<\/jats:italic> were predicted and examined by LC-MS\/MS. After reduction, alkylation, and tryptic digestion were performed on Hemocoagulase <jats:italic>Agkistrodon halys pallas<\/jats:italic>, a target peptide TLCAGVMEGGIDTCNR was analyzed by LC-MS\/MS-MRM. It offers a new and effective approach for the quality control of Hemocoagulase <jats:italic>Agkistrodon halys pallas<\/jats:italic> products. This method is superior to the current assays in terms of sensitivity, specificity, precision, accuracy, and throughput. The strategy can also be applied in studying other important protein-based medicines.<\/jats:p>","DOI":"10.3389\/fmolb.2022.831293","type":"journal-article","created":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T07:29:27Z","timestamp":1654068567000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A Species-Specific Strategy for the Identification of Hemocoagulase Agkistrodon halys pallas Based on LC-MS\/MS-MRM"],"prefix":"10.3389","volume":"9","author":[{"given":"Ruiqing","family":"Xian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Congcong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liping","family":"Gong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baojian","family":"Hang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weijian","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xunjie","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongmin","family":"Du","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengshan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,5,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"4313","DOI":"10.2147\/JIR.S322430","article-title":"Alterations in the Plasma Proteome Induced by SARS-CoV-2 and MERS-CoV Reveal Biomarkers for Disease Outcomes for COVID-19 Patients","volume":"14","author":"Alaiya","year":"2021","journal-title":"Jir"},{"key":"B2","doi-asserted-by":"publisher","first-page":"650604","DOI":"10.3389\/fmolb.2021.650604","article-title":"Identification of Proteomic Signatures in Chronic Obstructive Pulmonary Disease Emphysematous Phenotype","volume":"8","author":"Bai","year":"2021","journal-title":"Front.
