分子别名(Synonym)

Delta3,delta-like 3 (Drosophila),delta-like protein 3,DLL3,Pudgy,SCDO1,SCDO1delta3

表达区间及表达系统(Source)

FITC-Labeled Human DLL3, His Tag (DL3-HF2H4) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Leu 492 (Accession # Q9NYJ7-1).

Predicted N-terminus: Ala 27

蛋白结构(Molecular Characterization)

Online(Ala 27 - Leu 492) Q9NYJ7-1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 50.4 kDa. The protein migrates as 50-55 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

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 seive treatment during purification process.

蛋白标记度(FITC:Protein Ratio)

The FITC to protein molar ratio is 2-4.

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, Arginine, pH7.4. Normally trehalose is added as protectant before lyophilization.

Protocol

背景(Background)

Delta-like protein 3 (DLL3) is a transmembrane protein that belongs to the Delta/Serrate/Lag-2 (DSL) family of Notch ligands.May be required to divert neurons along a specific differentiation pathway. Plays a role in the formation of somite boundaries during segmentation of the paraxial mesoderm. DLL3 protein is expressed on the surface of tumor cells but not in normal adult tissues.
