Recombinant SARS-CoV-2 Spike RBD Protein, His tag (Animal-Free)

The recombinant SARS-CoV-2 (COVID-19) Spike RBD protein consists of 229 amino acids and predicts a molecular mass of 26.5 kD.The apparent molecular mass of the human CD33 is approximately 32-35 kDa in SDS-PAGE under reducing conditions due to glycosylation.

>95% as determined by SDS-PAGE

Endotoxin: < 1 EU per ug of the protein as determined by the LAL method.

Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized SARS-CoV-2 (COVID-19) S protein RBD protein not less than 100 ug/mL, which can then be further diluted to other aqueous solutions.

The product is shipped at ambient temperature.

COVID-19 has become pandemic with higher morbidity and mortality rates after its start from Wuhan city of China. The infection by RNA virus, also known as SARS-CoV-2 or 2019-nCoV, from beta class of corona viruses has been found to be responsible for COVID-19. Structural analysis and evidences have been indicated that interaction between a segment of receptor binding domain (RBD) from S protein of virus and human angiotensin-converting enzyme 2 (hACE2) is essential for cellular entry of virus. Inhibition of RBD-hACE2 interaction by different molecular scaffolds can be used as a preferred strategy for control of SARS-CoV-2 infection.
