PE-Labeled Human Mesothelin (296-580), His Tag (MSN-HP2H5) is produced via site-specific conjugation of PE to Human Mesothelin (296-580), His Tag under optimal conditions with a proprietary technology. Human Mesothelin (296-580), His Tag is expressed in HEK293 cells containing AA Glu 296 - Gly 580 (Accession # AAH09272).
Predicted N-terminus: Glu 296
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 35.9 kDa.

1e6 of the anti-MSLN CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of PE-Labeled Human Mesothelin (296-580) Protein, His Tag (Cat. No. MSN-HP2H5) and negative control protein respectively, PE signal was used to evaluate the binding activity (QC 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.
