分子别名（Synonym）

Spike,S1 protein,Spike glycoprotein Subunit1,S glycoprotein Subunit1,Spike protein S1

表达区间及表达系统（Source）

Biotinylated SARS-CoV-2 S1 protein, His,Avitag (S1N-C82E9) is expressed from human 293 cells (HEK293).

蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 78.6 kDa. The protein migrates as 100-150 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Labeling）
