Protocol

Spike protein ELISA

Immobilized Anti-SARS-CoV-2 RBD Neutralizing Antibody, Human IgG1 (Cat. No. SAD-S35) at 1 μg/mL (100 μL/well) can bind SARS-CoV-2 S protein, His Tag, Super stable trimer (Cat. No. SPN-C52H7) with a linear range of 0.2-3 ng/mL (Routinely tested).

Protocol

 

背景(Background)

It's been reported that SARS-CoV-2 can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
