表达区间及表达系统(Source)

Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (MSN-H82E9) is expressed from human 293 cells (HEK293). It contains AA Glu 296 - Gly 580 (Accession # AAH09272.1 ).

Predicted N-terminus: Glu 296

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

蛋白结构(Molecular Characterization)

Mesothelin Structure

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 35.9 kDa. The protein migrates as 38-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Labeling)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Protein Ratio)

Passed as determined by the HABA assay / binding ELISA.

内毒素(Endotoxin)

Less than 0.01 EU per μg by the LAL method.

无菌(Sterility)

The sterility testing was performed by membrane filtration method.

支原体(Mycoplasma)

Negative.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Report

 

活性(Bioactivity)-FACS

Mesothelin FACS

2e5 of Anti-MSLN CAR-293 cells were stained with 100μL of 1 μg/mL of Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9) and negative control protein respectively, washed and then followed by PE-SA and analyzed with FACS (QC tested).

Protocol

 

活性(Bioactivity)-ELISA

Mesothelin ELISA

Immobilized Anti-Human MSLN MAb at 0.5 μg/mL (100 μL/well) can bind Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9) with a linear range of 0.1-0.78 ng/mL (QC tested).

Protocol

 

CAR阳性表达率检测(Evaluation of CAR expression)

FACS Analysis of Anti-MSLN CAR Expression

Mesothelin CAR_T

293 cells were transfected with Anti-MSLN-scFv and RFP tag. 2e5 of the cells were first stained with B. Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9, 3 µg/mL) and C. Biotinylated Protein Control, followed by FITC Streptavidin. A. Non-transfected 293 cells and C. Biotinylated Protein Control were used as negative control. RFP was used to evaluate CAR (Anti-MSLN-scFv) expression and FITC was used to evaluate the binding activity of Biotinylated Human Mesothelin (296-580), His,Avitag, premium grade (Cat. No. MSN-H82E9).

 

背景(Background)

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.
