表达区间及表达系统（Source）
FITC-Labeled Human EGF R, His Tag (EGR-HF2H5) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Ser 645 (Accession # P00533-1). It is the FITC labeled form of Human EGF R, His Tag (EGR-H5222).
Predicted N-terminus: Leu 25
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 70.5 kDa. The protein migrates as 85-105 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.

电泳（SDS-PAGE）
FITC-Labeled Human EGF R, 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 Cetuximab at 2 μg/mL (100 μL/well) can bind FITC-Labeled Human EGF R, His Tag (Cat. No. EGR-HF2H5) with a linear range of 0.039-0.313 μg/mL (QC tested).
Protocol
活性（Bioactivity）-FACS
2e5 of Anti-EGFR CAR-293 cells were stained with 100 μL of 1 μg/mL of FITC-Labeled Human EGF R Protein, His Tag (Cat. No. EGR-HF2H5) and negative control protein respectively, FITC signal was used to evaluate the binding activity (QC tested).
