Name : Human MSLN/Mesothelin Protein
Product Source :
Recombinant Human MSLN/Mesothelin Protein is expressed from HEK293 with His tag at the C-terminus. It contains Glu296-Ser598.[Accession | Q13421-3]
Molecular Weight :
The protein has a predicted MW of 35.23 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human MSLN on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human MSLN is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human MSLN, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human CA125, His Tag with the EC50 of 11.7ng/ml determined by ELISA (QC Test). ELISA Data Immobilized Human MSLN, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-MSLN Antibody, hFc Tag with the EC50 of 2.9ng/ml determined by ELISA.
Background :
Mesothelin, also known as MSLN, is a protein that in humans is encoded by the MSLN gene.Cloning studies showed that the mesothelin gene encodes a precursor protein that is processed to yield mesothelin which is attached to the cell membrane by a glycophosphatidylinositol linkage and a 31-kDa shed fragment named megakaryocyte-potentiating factor (MPF). Although it has been proposed that mesothelin may be involved in cell adhesion, its biological function is not known.A knockout mouse line that lacks mesothelin reproduces and develops normally.
Synonyms :
MSLN; CAK1; Mesothelin; MPF; MPFSMRP; SMR
