Human Mesothelin (296-580), His Tag, low endotoxin (MSN-H522a) is expressed from human 293 cells (HEK293). It contains 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 33.0 kDa. The protein migrates as 38-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 0.01 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
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, low endotoxin on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human Mesothelin (296-580), His Tag, low endotoxin (Cat. No. MSN-H522a) at 0.5 μg/mL (100 μL/well) can bind Anti-MSLN MAb, Human IgG1 with a linear range of 0.2-3 ng/mL (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.
