表达区间及表达系统（Source）
Biotinylated Human BAFF Protein, Avitag,Fc Tag (BAF-H82F3) is expressed from human 293 cells (HEK293). It contains AA Ala 134 - Leu 285 (Accession # AAH20674.1).
Predicted N-terminus: Gly
Request for sequence蛋白结构（Molecular Characterization）
This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a human IgG1 Fc tag.
The protein has a calculated MW of 44.9 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Biotin
