FITC-Labeled Human IgG1 Fc (C103S, M135Y, S137T, T139E, H316K, N317F) Protein, His Tag (MALS verified)
分子别名（Synonym）
IgG1
表达区间及表达系统（Source）
FITC-Labeled Human IgG1 Fc Protein, His Tag (IG1-HF2H3) is expressed from human 293 cells (HEK293). It contains AA Glu 99 - Lys 330 (Accession # P01857-1 (C103S, M135Y, S137T, T139E, H316K, N317F)).
Predicted N-terminus: Glu 99
蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 28.1 kDa. The protein migrates as 33-37 kDa and 65-66 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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 1-3.
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.

背景介绍
Crystallizable fragments composed of the carboxy-terminal halves of both IMMUNOGLOBULIN HEAVY CHAINS linked to each other by disulfide bonds. Fc fragments contain the carboxy-terminal parts of the heavy chain constant regions that are responsible for the effector functions of an immunoglobulin (COMPLEMENT fixation, binding to the cell membrane via FC RECEPTORS, and placental transport). IgG1 Fc was reported has a novel role as a potential anti-inflammatory drug for treatment of human autoimmune diseases.
