Biotinylated Mouse MSLN/Mesothelin Protein (Primary Amine Labeling)

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Mouse MSLN/Mesothelin Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus.
It contains Asp298-Ser600 [Accession | Q61468-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 35.2 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 90% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

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 the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

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

SEC-HPLC

The purity of Biotinylated Mouse MSLN is greater than 90% as determined by SEC-HPLC.

ELISA Data

Immobilized Human CA125, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Mouse MSLN, His Tag with the EC50 of 0.79μg/ml determined by ELISA (QC Test).

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.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
