To "prepare a piece" involving , the process typically refers to the laboratory synthesis and purification of a specific fragment of the SARS-CoV-2 Spike (S) protein for use in research or vaccine development. Preparation Protocol for RBD-991
: The synthesized fragment is ligated into the vector using kits like the ClonExpress® Ultra One Step Cloning Kit and then transformed into a host like E. coli XL1-Blue . RBD-991
In molecular biology, "RBD-991" identifies a DNA sequence fragment starting at the of the SARS-CoV-2 S protein gene (GenBank: NC_045512.2). To "prepare a piece" involving , the process
