SARS-CoV-2 S1 protein (N501Y), His Tag (S1N-C52Hg) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1(N501Y)). N501Y mutaion was identified in both the SARS-CoV-2 variant (known as 20B/501Y.V1, VOC 202012/01, or B.1.1.7 lineage) which emerged in the United Kindom and SARS-CoV-2 variant (known as 20C/501Y.V2 or B.1.351 lineage) which emerged in South Africa.
Predicted N-terminus: Val 16
Online(Val 16 - Arg 685) QHD43416.1 (N501Y)Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 76.9 kDa. The protein migrates as 110-130 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
