产品详情

SARS-CoV-2 Spike RBD (L452Q, F490S) Protein (His Tag)

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 (L452Q, F490S) Protein (His Tag)(Cat:40592-V08H113), the EC50 of SARS-CoV-2 Spike RBD (L452Q, F490S) Protein (His Tag)(Cat:40592-V08H113) is 8-48 ng/mL.

蛋白构建：A DNA sequence encoding the SARS-CoV-2 Spike RBD (YP_009724390.1, with mutations L452Q, F490S) (Arg319-Phe541) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as variant C.37) which emerged in the Peru.

NP No.：YP_009724390.1

表达宿主：HEK293 Cells

种属：SARS-CoV-2

预测 N 端：Arg 319

分子量：The recombinant SARS-CoV-2 Spike RBD consists of 234 amino acids and predicts a molecular mass of 26.50 kDa. As a result of glycosylation, it migrates as an approximately 33.47 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.
