This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 35.9 kDa. The protein migrates as 40-50 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
The purity of Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9) is more than 85% and the molecular weight of this protein is around 38-53 kDa verified by SEC-MALS.
2e5 of Anti-MSLN CAR-293 cells were stained with 100μL of 1 μg/mL of Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9) and negative control protein respectively, washed and then followed by PE-SA and analyzed with FACS (QC tested).
Immobilized Anti-Human MSLN MAb at 0.5 μg/mL (100 μL/well) can bind Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9) with a linear range of 0.1-0.78 ng/mL (QC tested).
293 cells were transfected with Anti-MSLN-scFv and RFP tag. 2e5 of the cells were first stained with B. Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9, 3 µg/mL) and C. Biotinylated Protein Control, followed by FITC Streptavidin. A. Non-transfected 293 cells and C. Biotinylated Protein Control were used as negative control. RFP was used to evaluate CAR (Anti-MSLN-scFv) expression and FITC was used to evaluate the binding activity of Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9).
