Recombinant 2019-nCoV(SARS-CoV-2) Spike Protein RBD L452R mutant (double mutant variant B.1.617 lineage, S:E484Q+L452R (India))

The world is in midst of the COVID-19 pandemic. Recently A new "double mutant" variant of the coronavirus has been detected from samples collected in India. The two mutations (E484Q and L452R mutations) come together in the same virus, may be more infectious or less affected by vaccines.1

Mutations of Spike protein in SARS-COV-2 (2019nCOV) double mutant variant B.1.617 lineage, S:E484Q+L452R (India)
Two of the spike mutations are at key residues in the RBD (E484Q and L452R), two are in the N-terminal domain (T95I and E154K).
