SARS-CoV-2 S1 (RBD) Epsilon, B.1.427/B.1.429 (California/USA), GFP/His-Tag Size:100µg Product Name: G4 EA H1N1_HA1_His-TagRecombinant protein of the receptor binding domain (RBD), Mutant (L452R) of SARS CoV 2 (COVID 2019) Spike S1 from Wuhan pneumonia virus with C terminal GFP His Tag. The mutation L452R is characteristic for the SARS CoV 2 virus variants B. 1. 427 or B. 1. 429 emerged in California USA. These variants are also known as CAL. 20C. The mutation is affecting the receptor binding domain (RBD) of the spike protein, which the virus uses to bind to human cells
