The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates thisinteraction.The S protein plays key parts in the induction of neutralizing-antibody and T-cellresponses, as well as protective immunity.
Recombinant SARS-COV-2(2019-nCoV) Spike S1 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln14-Arg683) of SARS-COV-2(2019-nCoV) Spike S1 (Accession #YP_009724390.1) fused with a 6XHis tag and Avi at the C-terminus.
以2μg/mL(100 μL/孔)的固定化重组SARS-CoV-2 Spike S1可与重组人ACE 2结合,线性范围为0.15- 6.85ng/mL。|在COOH芯片上固定的人ACE 2,可以结合SARS-COV-2 Spike S1,在SPR测定中测定的亲和常数为24.5nM。
对于冻干蛋白:在无菌蒸馏水中复溶至0.1-0.5 mg/mL的浓度。
冻干蛋白质在-20 ° C至-80 ° C下长期储存。复溶后,蛋白质溶液在-20 ° C下可稳定储存3个月,在2-8 °C下可稳定储存1周。本品在≤ -70 ° C下自接收之日起可稳定储存6个月。为获得最佳储存条件,离心后分装成少量,并在推荐温度下储存。
