Catalog Number:
B90Y94
Description:
A recombinant form of the receptor binding domain (RBD with amino acids 319 to 541) of the spike (S) glycoprotein gene from severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) Omicron BA.4/5 strain was produced by insect cells, followed by purification. This product contains C-terminal 6 hexa-histidine tag. Amino acid sequence is rvqptesivrfpnitnlcpfdevfnatrfasvyawnrkrisncvadysvlynfapffafkcygvsptklndlcftnvyadsfvirgnevsqiapgqtgniadynyklpddftgcviawnsnkldskvggnynyryrlfrksnlkpferdisteiyqagnkpcngvagvncyfplqsygfrptygvghqpyrvvvlsfellhapatvcgpkkstnlvknkcvnftghhhhhh. This product has been run on SDS-PAGE with reduced condition. We also evaluated its binding to ACE2-Fc, anti-His mAb and a negative mAb in ELISAs.
