蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 25.8 kDa. The protein migrates as 42-60 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.
蛋白标记度（Protein Ratio）
The FITC to protein molar ratio is 1.5-3.5.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

活性（Bioactivity）-ELISA
Immobilized Anti-Syndecan-1 antibody, Mouse IgG1 at 1 μg/mL (100 μL/well) can bind FITC-Labeled Human Syndecan-1, His Tag (Cat. No. SD1-HF228) with a linear range of 0.078-2.5 μg/mL (QC tested).
Protocol
活性（Bioactivity）-FACS
2e5 of anti-Syndecan-1 CAR-293 cells were stained with 100 μL of 3 μg/mL of FITC-Labeled Human Syndecan-1, His Tag (Cat. No. SD1-HF228) and negative control protein respectively, FITC signals was used to evaluate the binding activity (QC tested).
Protocol
背景（Background）
Syndecan-1 (SYND1 or SDC1) is also known as CD antigen CD138, is a transmembrane (type I) heparan sulfate proteoglycan and is a member of the syndecan proteoglycan family. The syndecans mediate cell binding, cell signaling, and cytoskeletal organization and syndecan receptors are required for internalization of the HIV-1 tat protein. The syndecan-1 / SDC1 protein functions as an integral membrane protein and participates in cell proliferation, cell migration and cell-matrix interactions via its receptor for extracellular matrix proteins. It is a useful marker for plasma cells, but only if the cells tested are already known to be derived from blood.
