SARS-CoV-2 Spike RBD (K417N, E484K, N501Y) Protein (His & AVI Tag), Biotinylated
纯度:> 95 % as determined by SDS-PAGE.
内毒素:< 1.0 EU per μg protein as determined by the LAL method.
生物活性:Immobilized ACE2 Protein, Human, Recombinant (mFc Tag)(Cat: 10108-H05H) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 Spike RBD (K417N, E484K, N501Y) Protein (His & AVI Tag), Biotinylated(Cat: 40592-V49H3-B), the EC50 of SARS-CoV-2 Spike RBD (K417N, E484K, N501Y) Protein (His & AVI Tag), Biotinylated(Cat: 40592-V49H3-B) is 5-30 ng/mL.
蛋白构建:A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutation K417N, E484K, N501Y) (Arg319-Phe541) was expressed with a c-terminal polyhistidine tagged AVI tag at the C-terminus. The purified protein was biotinylated in vitro. The mutations were identified in the SARS-CoV-2 variant (known as variant B.1.351) which emerged in the South Africa.
NP No.:YP_009724390.1
表达宿主:HEK293 Cells
种属:SARS-CoV-2
预测 N 端:Ser
分子量:The recombinant SARS-CoV-2 Spike RBD consists of 250 amino acids and predicts a molecular mass of 28.48 kDa. As a result of glycosylation, it migrates as an approximately 36.17 kDa band in SDS-PAGE under reducing conditions.
缓冲液:Lyophilized from sterile PBS, pH 7.4.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件:Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
