Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 77.0 kDa. The protein migrates as 100-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Conjugate
FITC
Excitation source: 488 nm spectral line, argon-ion laser
Excitation Wavelength: 488 nm
Emission Wavelength: 535 nm
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.
Protein Ratio
The FITC to protein molar ratio is 3-5.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

SDS-PAGE
FITC-Labeled Human Siglec-2, 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%.
Bioactivity-ELISA
Immobilized Monoclonal Anti-Human CD22 Antibody, Human IgG1 at 10 μg/mL (100 μL/well) can bind FITC-Labeled Human Siglec-2, His Tag (Cat. No. SI2-HF2H6) with a linear range of 0.078-20 μg/mL (QC tested).
Protocol
Evaluation of CAR expression
FACS Analysis of Anti-CD22 CAR Expression
293 cells were transfected with anti-CD22-scFv and RFP tag. 2e5 of the cells were stained with B. FITC-Labeled Human Siglec-2, His Tag (Cat. No. SI2-HF2H6, 10 µg/mL) and C. FITC-labeled Protein Control. A. Non-transfected 293 cells and C. FITC-labeled Protein Control were used as negative control. RFP was used to evaluate CAR (anti-CD22-scFv) expression and FITC was used to evaluate the binding activity of FITC-Labeled Human Siglec-2, His Tag (Cat. No. SI2-HF2H6) (QC tested).
