Biotinylated Human CD20 Full Length, His,Avitag (CD0-H82E3) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the C-terminus followed by an Avi tag with calculated MW of 36.9 kDa and migrates as 43 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Biotinylated Human TNF-alpha, His, Avitag (TNA-H82E3) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™), and has a calculated MW of 20.0 kDa. The protein migrates as 21 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
