表达区间及表达系统（Source）
FITC-Labeled Human GUCY2C, His Tag (GUC-HF2H8) is expressed from human 293 cells (HEK293). It contains AA Ser 24 - Gln 430 (Accession # P25092-1). It is the FITC labeled form of Human GUCY2C, His Tag (GUC-H52H5).
Predicted N-terminus: Ser 24
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 47.9 kDa. The protein migrates as 60-90 kDa 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.
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.

数据展示
电泳（SDS-PAGE）
FITC-Labeled Human GUCY2C, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
活性（Bioactivity）-ELISA
Immobilized Monoclonal Anti-Human GUCY2C Antibody, Human IgG1 at 5 μg/mL (100 μL/well) can bind FITC-Labeled Human GUCY2C, His Tag (Cat. No. GUC-HF2H8) with a linear range of 0.156-0.625 μg/mL (QC tested).
Protocol
活性（Bioactivity）-FACS
2e5 of anti-GUCY2C CAR-293 cells were stained with 100 μL of 1 μg/mL of FITC-Labeled Human GUCY2C, His Tag (Cat. No. GUC-HF2H8) and negative control protein respectively. FITC signal was used to evaluate the binding activity (QC tested).
