SARS-CoV-2抗體
新冠病毒引起的新冠肺炎疫情此起彼伏，對全球的醫療衛生系統和經濟帶來了巨大影響，同時也給新冠疫苗、治療藥物以及診斷帶來了新的挑戰。武漢華美生物一直密切關注新冠病毒的進化情況，目前已開發了大量高質量SARS-CoV-2相關抗體試劑，包括N抗體、S抗體、S RBD納米抗體、N抗體對和S RBD抗體對等。
其中，N抗體與S抗體可用于新冠病毒致病性機理研究，可通過WB定性檢測新冠抗原；N抗體對和S RBD抗體對可用于新冠試劑盒的開發；另外，部分抗體驗證了中和試驗和主流突變株檢測，可作為質控品，應用于針對突變株的中和抗體篩選、重組蛋白疫苗研發、疫苗接種后血清中的中和抗體檢測等。
