分子别名（Synonym）
CD5, LEU1
表达区间及表达系统（Source）
Alexa Fluor 488-Labeled Human CD5 Protein, Fc Tag (CD5-HA253) is expressed from human 293 cells (HEK293). It contains AA Arg 25 - Pro 372 (Accession # P06127-1). It is the Alexa Fluor™ 488 labeled form of Human CD5, Fc Tag (Cat. No. CD5-H5253).
Predicted N-terminus: Arg 25
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 65.1 kDa.
偶联（Conjugate）
AF488
Excitation Wavelength: 488 nm
Emission Wavelength: 517 nm
标记（Labeling）
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with AF488 using standard chemical labeling method. The residual AF488 is removed by molecular sieve treatment during purification process.
蛋白标记度（Protein Ratio）
The AF488 to protein molar ratio is 2.1-3.4.
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.

数据展示
活性（Bioactivity）-ELISA
Immobilized Alexa Fluor 488-Labeled Human CD5 Protein, Fc Tag (Cat. No. CD5-HA253) at 1 μg/mL (100 μL/well) can bind Mouse Anti-CD5 Antibody, Mouse IgG1 with a linear range of 0.1-4 ng/mL (Routinely tested). Labeling with fluorescent dyes did not affect their activity.
Protocol
活性（Bioactivity）-FACS
1e5 of Mouse Anti-CD5 antibody coupled beads (5.5 μm) were stained with different concentration of Alexa Fluor 488-Labeled Human CD5 Protein, Fc Tag (Cat. No. CD5-HA253) and negative control protein respectively, AF488 signal was used to evaluate the binding activity (QC tested).
