Swiss Prot: QHD43416.1

Source: Recombinant SARS-CoV-2 Spike RBD protein is expressed in HEK293 with Fc-Avi. It contains the amino acid sequence of Arg319-Asn532.

Storage Buffer: Lyophilized from 0.22um filtered solution in 20mM PB (pH 7.4). 5% trehalose is added as a protectant before lyophilization.

Storage: The product should be stored at -70°C or -20°C.


The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensinconverting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Endotoxin: Less than 1EU per ug by the LAL method.
