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.

FITC-Labeled Human GPRC5D Full Length Protein, Flag,His Tag (GPD-HF2D6) is expressed from human 293 cells (HEK293). This protein carries a Flag tag at the N-terminus and a polyhistidine tag at the C-terminus. The protein has a calculated MW of 37.9 kDa.

Human Claudin-18.2 Full Length Protein-VLP (CL2-H52P7) is expressed from human 293 cells (HEK293). Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrane Proteins can be constituted in-situ with VLPs produced from HEK293 cell cultures.

Human VEGF165, His Tag (VE5-H5248) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the N-terminus, and has a calculated MW of 21.1 kDa. The protein migrates as 27-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Human TNF-alpha Protein, His Tag (TNA-H5228) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the C-terminus, and has a calculated MW of 18.3 kDa. The protein migrates as 17-19 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Biotinylated Human VEGF165, His,Avitag(VE5-H82Q0) is expressed from human 293 cells (HEK293). It carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™), and has a calculated MW of 22.4 kDa (monomer). The protein migrates as 25-33 kDa (monomer) under reducing (R) condition, and 42-55 kDa (homodimer) under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
