Labelling

Fluorescein-DBCO is a fluorescein dye labeling reagent containing a DBCO group, which can react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fluorescein-PEG4-azide is a green emitting fluorescent dye derivitative with excitation/emmission maximum 494/517 nm containing an azide group, which enables Click Chemistry. The hydophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BDP FL-PEG5-azide is a PEG linker with an azide group and BDP FL dye moiety. The azide group enables Click Chemistry and BDP FL dye moiety is highly compatible with FAM fluorescence measuring instruments. The hydrophilic PEG spacer arm increases water solubility and a membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BDP FL-PEG5-propargyl is a BDP FL linker containing a reactive propargyl group and a hydrophilic PEG spacer arm. The propargyl group allows site-specific conjugation by Click Chemistry and is ideal for conjugation with of antibodies, proteins or probes. The hydrophilic PEG spacer arm can increase water solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

TAMRA acid, mixed isomers, has achieved prominence as a dye for oligonucleotide labeling and automated DNA sequencing applications. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BDP FL DBCO is afluorescent reagent containing a reactive DBCO group, DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BDP FL-PEG5-acid is a BDP FL acid linker containing a hydrophilic PEG spacer arm. BDP FL is a green-fluorescent dye and the hydrophilic PEG spacer arm increases water solubility as well as membrane permability. BDP FL dye has several characteristics that make it potentially superior in some applications, including high extinction coefficient, high fluorescence quantum yield, narrow emission bandwidth, red shift in fluorescence emission at high dye concentrations, relatively long excited-state lifetime, etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG3)-N-Fluorescein-PEG3-acid contains azide, fluorescein and carboxylic acid moieties. The azide can react with alkynes in copper-catalyzed Click Chemistry. Fluorescein is a universal dye which is used for dye labeling. The carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU. The hydrophilic PEG linker increases the compounds water solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Heptamethine cyanine dye-1, a near-infrared cyanine dye, is used for fluorescence imaging in biological systems.
