Species:

SARS-COV-2

Expression System:

HEK293

Molecular Weight: 

The protein has a predicted MW of 26.21 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Bis-Tris PAGE result.

Target Name:

Spike RBD (Omicron XBB)

Target Information:

The ongoing coronavirus disease 2019 (COVID-19) pandemic has prioritized the development of small-animal models for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The resulting mouse-adapted strain at passage 6 (called MASCp6) showed increased infectivity in mouse lung and led to interstitial pneumonia and inflammatory responses in both young and aged mice after intranasal inoculation. Deep sequencing revealed a panel of adaptive mutations potentially associated with the increased virulence. In particular, the N501Y mutation is located at the receptor binding domain (RBD) of the spike protein.
