SARS-CoV-2 Membrane Protein, Recombinant, AviTag

The coronavirus membrane protein (M protein) is a major structural component of the viral envelope and a determinant of virus assembly.

A DNA sequence encoding the SARS-CoV-2 M protein was expressed with a polyhistidine tag and AviTag at the N-terminus. 

Catalog number: COVM-301

Expression host: Escherichia coli (E. coli).
