OVERVIEW | |
CATALOG # | bs-46009P |
PRODUCT NAME |
Recombinant SARS-CoV-2 Spike RBD
|
CONJUGATION | Unconjugated |
SOURCE |
SARS-CoV-2 S protein RBD is expressed from a mammalian cell line with a mouse Fc tag at the C-terminal. It contains Arg319-Asn532. |
EXPRESSION SYSTEM |
HEK293 |
TAG | mFc-Tag |
MOLECULAR WEIGHT | The protein has a predicted MW of 49.7kDa. Due to glycosylation, the protein migrates to 60-70KDa based on Bis-Tris PAGE result. |
ENDOTOXIN |
Less than 0.5 EU per ug by the LAL method. |
PURITY: |
> 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC |
FORMULATION |
Lyophilized from 0.22um filtered solution in 20mM PB (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization. |
STORAGE |
The product should be stored at -70℃ or -20℃. |
TARGET | |
ACCESSION |
QHD43416.1 |
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. |
