Recombinant SARS-CoV-2 (COVID-19) Envelope protein, GST, His Tag, 100µg

Background
The SARS-CoV-2 is composed of a double-layered lipid envelope, including Spike glycoprotein (S), Envelope protein (E), Membrane glycoprotein (M), and Nucleocapsid protein (Nucleocapsid protein, N). Among them, The amino acid sequence of the SARS-CoV-2 envelope protein is 95% identical of the SARS envelope protein.

Source
Recombinant SARS-CoV-2 Envelope protein, GST,His Tag (ENN-C5128) is expressed from E.coli cells. It contains AA Met 1 - Val 75 (Accession # QHU79206.1).
Predicted N-terminus: Met

Molecular Characterization
This protein carries a GST tag at the N-terminus and a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 36.8 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE).

Endotoxin
Less than 1.0 EU per μg by the LAL method.
