DATASHEET

Entrez Gene: QHD43416.1

Source: Recombinant SARS-COV-2 Spike S Trimer Protein protein is expressed in HEK293 with His-Avi. It contains the amino acid sequence of  Val16-Glu1188.

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.

Background:

The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting 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.

Sequence:  Val16-Glu1188

Size: 1mg, 100µg

Applications: WB
ELISA
HPLC

Mol. Wt.: 136


Species: SARS-CoV-2
