詳細

詳細

SARS-CoV-2 belongs to Coronaviridae (CoVs) - a large family of viruses that usually cause mild to moderate upper-respiratory tract diseases.1 CoVs are single-stranded RNA viruses. They have a high mutation rate and are therefore highly diverse.1 Their hosts include human and non-human mammals, as well as birds.1

特異性

This product is expressed in human HEK 293 cells as a glycoprotein with a calculated molecular mass of 25 kDa (amino acids 319- 541) and includes a C-terminal polyhistidine tag.

アプリケーション

The activity of this product is tested by a functional ELISA. Immobilization of Spike protein Receptor Binding Domain at 2 μg/mL (100 μL/well), allows binding of ACE2, biotin tagged (Cat. No. SAE0171). The half maximal binding (binding which produces 50% of the optimal binding response) is ≤2 μg/mL.

生物化学的／生理学的作用

SARS-CoV-2 infects cells which express angiotensin converting enzyme 2 (ACE2).2 ACE2 binds to the viral envelope-associated spike (S) protein as a cellular receptor, following proteolytic cleavage of both S and ACE2 by serine proteases.3 The receptor binding domain (RBD) of S protein is the domain that specifically binds to ACE2.

物理的形状

This product is supplied as a lyophilized powder in phosphate buffered saline (PBS), pH 7.4, with no carrier proteins.

保管および安定性

Store the product at –20 °C. The product retains its activity for at least 2 years as supplied. After initial thawing, it is recommended to store the protein in working aliquots at –20 °C.
