This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 33.0 kDa. The protein migrates as 34-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human Mesothelin (296-580), His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Human Mesothelin (296-580), His Tag(Cat. No. MSN-H5223) was more than 90% and the molecular weight of this protein is around 35-55 kDa verified by SEC-MALS.
Anti-Human MSLN MAb (chimeric mouse-human IgG1) captured on CM5 chip via Anti-Human IgG Fc antibodies surface, can bind Human Mesothelin (296-580), His Tag (Cat. No. MSN-H5223) with an affinity constant of 0.518 nM as determined in a SPR assay (Biacore T200) (Routinely tested).
Loaded Anti-Human MSLN MAb (chimeric mouse-human IgG1) on Protein A Biosensor, can bind Human Mesothelin (296-580), His Tag (Cat. No. MSN-H5223) with an affinity constant of 0.948 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
293 cells were transfected with anti-MSLN-scFv and RFP tag. 2e5 of the cells were first stained with B. Human Mesothelin (296-580), His Tag (Cat. No. MSN-H5223, 1 µg/mL) and C. His Tag protein control, followed by FITC-conjugated anti-6xHis tag antibody. A. Non-transfected 293 cells and C. His Tag-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 Human Mesothelin (296-580), His Tag (Cat. No. MSN-H5223).
