Recombinant COVID-19 Spike RBD + SD1 + SD2 protein, His-tagged

• Cat.No.: Spike-210V
• Product Overview: Recombinant COVID-19 spike protein receptor binding domain together with subdomain 1 and subdomain 2 (Glu309-Ala684), fused to His-tag at the C-terminus, was expressed in HEK293F.

Specification

• Description: It's been reported that COVID-19 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.
