蛋白结构(Molecular Characterization)

FAP Structure

This protein carries a human IgG1 Fc tag at the N-terminus

The protein has a calculated MW of 111.5 kDa. The protein migrates as 115-130 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

偶联(Conjugate)

FITC

Excitation source: 488 nm spectral line, argon-ion laser

Excitation Wavelength: 488 nm

Emission Wavelength: 535 nm

标记(Labeling)

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular sieve treatment during purification process.

蛋白标记度(Protein Ratio)

The FITC to protein molar ratio is 2-4.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

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.

电泳(SDS-PAGE)

FAP SDS-PAGE

FITC-Labeled Human FAP, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

 

活性(Bioactivity)-ELISA

FAP ELISA

Immobilized Anti-FAP Antibody, Mouse IgG2a (FAP5) at 1 μg/mL (100 μL/well) can bind FITC-Labeled Human FAP, Fc Tag (Cat. No. FAP-HF263) with a linear range of 0.02-0.313 μg/mL (QC tested).

Protocol

 

活性(Bioactivity)-FACS

FAP FACS

2e5 of anti-FAP CAR-293 cells were stained with 100 μL of 3 μg/mL of FITC-Labeled Human FAP, Fc Tag (Cat. No. FAP-HF263) and negative control protein respectively, FITC signal was used to evaluate the binding activity (QC tested).

Protocol

 

背景(Background)

FAP (also known as seprase) is a Type II transmembrane serine protease. Both plasma membrane and soluble forms exhibit post-proline cleaving endopeptidase activity, with a marked preference for Ala/Ser-Gly-Pro-Ser/Asn/Ala consensus sequences. Degrade also gelatin, heat-denatured type I collagen. Also has dipeptidyl peptidase activity, with a preference for Ala-Pro, Ile-Pro, Gly-Pro, Arg-Pro and Pro-Pro. The plasma membrane form, in association with either DPP4, PLAUR or integrins, is involved in the pericellular proteolysis of the extracellular matrix (ECM), and hence promotes cell adhesion, migration and invasion through the ECM. Promotes glioma cell invasion through the brain parenchyma by degrading the proteoglycan brevican. Acts as a tumor suppressor in melanocytic cells through regulation of cell proliferation and survival in a serine protease activity-independent manner.
