一般描述
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) or (2019-nCoV) is a novel coronavirus that had spread on December 2019 in Hubei province of China and infected millions of people worldwide.1 The causative agent of COVID-19, the SARS-CoV-2 virus is a positive-strand RNA virus .The mature SARS-CoV-2 contains 4 structural proteins: Envelope (E), Membrane (M), Nucleocapsid (N), and the Spike protein (S), E and M proteins help in viral assembly and N protein is needed for RNA synthesis.
特异性
Monoclonal Anti-SARS-COV-2-Spike-RBD region antibody specifically recognizes Spike from COVID-19 virus origin
应用
The antibody may be used in various immunochemical techniques including Immunoblotting and Elisa. Detection of the Spike RBD protein band by Immunoblotting is specifically inhibited by the immunogen.
生化/生理作用
The Spike protein (S) is responsible for virus binding and entry into the host cells. SARS-CoV-2 S protein precursor is cleaved into S1 subunit (685 amino acids), and S2 (588 amino acids) subunits. S1 subunit harbor the receptor binding domain (RBD) that mediates virus entry into susceptible cells through the peptidase domain of host ACE2 with high affinity (Kd = 15 nM). S2 protein, which is reported to be well-conserved and showing 99% identity with bat coronavirus, is responsible for the membrane fusion. The Spike protein is the most studied between the coronaviruses proteins, due to its crucial role in the host cell entry , it contains the RBD for the ligand on the host cell membrane (the ACE2 protein), and also has epitopes recognized by T and B cells, which induce the production of neutralizing antibodies.2
外形
Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative
储存及稳定性
For continuous use, store at 2-8℃ for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
