Biotinylated Human MSLN/Mesothelin Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Human MSLN/Mesothelin Protein is expressed from Expi293 with hFc tag and Avi tag at the C-terminal. It contains Glu296-Gly580.[Accession | Q13421-2]

分子量大小(Molecular Weight)

The protein has a predicted MW of 61.1 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended (usually we use 1mg/ml solution for lyophilization). Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Biotinylated Human MSLN on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Biotinylated Human MSLN is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Anti-MSLN Antibody, hFc Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human MSLN, hFc Tag with the EC50 of 7.7ng/ml determined by ELISA.

FACS Data

Use Biotinylated Human MSLN-hFc-Avi protein to detect the expression rate of Anti-MSLN-CAR positive cell. 293T cells and anti-MSLN CAR-293T cells were incubated with Biotinylated human MSLN-hFc-Avi Tag. Non-transfected 293T cells and Fc-labeled protein control were used as negative control. SA-FITC was used to evaluate the binding activity of Biotinylated Human MSLN.

背景(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.
