SARS-CoV-2 S protein RBD (W436R), His Tag (SPD-S52H7) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Phe 541 (Accession # QHD43416.1(W436R)).
Predicted N-terminus: Arg 319
Online(Arg 319 - Phe 541) QHD43416.1 (W436R)Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 27.0 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
