Recombinant SARS-COV-2 Spike S1+S2 ECD(S-ECD) Protein (RP01260LQ)

Recombinant SARS-COV-2 S1+S2 ECD (S-ECD) Protein with His tag was determined by SDS-PAGE with Coomassie Blue, showing bands around 80,110,180 kDa.

Immobilized Recombinant SARS-COV-2 Spike S1+S2 ECD-His at 2μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-9.92 ng/mL.

纯度
>97% by SDS-PAGE.
内毒素
< 0.1 EU/μg of the protein by LAL method.
生物活性
Measured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike S1+S2 ECD-His at 2 μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-9.92 ng/mL.

背景信息

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.
