GFP Fusion Human Mesothelin (296-580), His Tag (MSN-HG2P4) is expressed from human 293 cells (HEK293). It contains AA Glu 296 - Gly 580 (Accession # AAH09272.1).
Predicted N-terminus: Ala 2
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 60.4 kDa. The protein migrates as 70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Flow cytometry (E.g. Evaluation of anti-MSLN CAR expression), fluorescence microscopy, etc.
Excitation source: 488 nm spectral line, argon-ion laser
Excitation Wavelength: 488 nm
Emission Wavelength: 530 nm
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Anti-human MSLN MAb (chimeric mouse-human IgG1) captured on CM5 chip via Anti-human IgG Fc antibodies surface, can bind GFP Fusion Human Mesothelin (296-580), His Tag (Cat. No. MSN-HG2P4) with an affinity constant of 0.542 nM as determined in a SPR assay (Biacore T200) (Routinely tested).
2e5 of the MSLN-CAR-293 cells were stained with 100 μL of 3 μg/mL of GFP Fusion Human Mesothelin (296-580), His Tag (Cat. No. MSN-HG2P4). GFP was used as negative control (Routinely tested).
Mesothelin (MSLN) is also known as CAK1 antigen, Pre-pro-megakaryocyte-potentiating factor, which belongs to the mesothelin family. Mesothelin / MSLN can be proteolytically cleaved into the following two chains by a furin-like convertase: Megakaryocyte-potentiating factor (MPF) and the cleaved form of mesothelin. Both MPF and the cleaved form of mesothelin are N-glycosylated. Mesothelin / MSLN can interacts with MUC16. The membrane-anchored forms of MSLN may play a role in cellular adhesion. MPF potentiates megakaryocyte colony formation in vitro.
