產品描述纖維蛋白原（Fibrinogen，Fg），即凝血因子I，分子量約340kDa，由α、β、γ三對不同多肽鏈組成，多肽鏈間以二硫鍵相連。α鏈分子量63.5kDa，β鏈分子量56kDa，γ鏈分子量47kDa，纖維蛋白原約含4%碳水化合物。纖維蛋白原參與凝血的原理：在凝血酶作用下，α鏈與β鏈分別釋放出A肽與B肽，生成纖維蛋白單體。在此過程中，由于釋放了酸性多肽，負電性降低，單體易于聚合成纖維蛋白多聚體，但此時單體之間借氫鍵與疏水鍵相連，尚可溶于稀酸和尿素溶液中。進一步在Ca2+與活化的ⅩⅢ因子作用下，單體之間以共價鍵相連，則變成穩定的不溶性纖維蛋白凝塊，完成凝血過程。來源于不同物種（如來源于牛、貓、狗、豚鼠、人、綿羊、小鼠和大鼠等）的纖維蛋白原具有相似的結構和性質。因此，一般來源于一種哺乳動物的纖維蛋白原可與其他來源的凝血酶交叉反應，相反地來自一種哺乳動物蛋白的凝血酶液也可注入多種動物，發生凝血反應。

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that also include MERS?CoV and SARS-CoV-1. Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N). The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 .The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). Before binding to the ACE-2 receptor, structural analysis of the S1 trimer shows that only one of the three RBD domains is in the "up" conformation. This is an unstable and transient state that passes between trimeric subunits but is nevertheless an exposed state to be targeted for neutralizing antibody therapy. Polyclonal antibodies to the RBD of the SARS-CoV-2 protein have been shown to inhibit interaction with the ACE-2 receptor, confirming RBD as an attractive target for vaccinations or antiviral therapy.  在分子生物學、生物化學或生物工程制藥研究中也常作為工具酶用于重組融合蛋白的特異性斷裂。Recombinant Rhesus macaque LILRB1/CD85j/ILT2 Protein,hFc Tag
