TAMRA-PEG2-Maleimide is a TAMRA red-fluorescent dye linker, with excitation/emission maximum 553/575 nm, containing a maleimide group which will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Dde TAMRA Biotin Alkyne is a trifunctional, cleavable probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a fluorescent dye (TAMRA) and biotin moiety linked to azide group through a spacer arm containing a hydrazine-cleavable Dde moiety. Under mild conditions (2% aqueous hydrazine), the Dde liner is cleaved, releasing the biotin tag and any avidin conjugate bound to it. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Pyrene-PEG5-biotin contains a pyrene group and biotinylation reagent. Pyrene can be used in the surface functionalization of carbon nanotube and graphene, graphene oxide, reduced graphene oxide. Pyrene shows strong pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes. The biotinylation can react with amine molecules in the presence of activator EDC or HATU. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein. The PEG moiety also increases solubility of Biotin-PEG conjugates considerably. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

A carbonyl-reactive hydrazide linker of Cyanine7.5 near infrared (NIR) fluorophore. This dye has similar spectral properties with ICG (indocyanine green), but has a higher quantum yield of fluorescence. Hence, this fluorophore is ideal for in vivo imaging.<br/>This is a carbonyl-reactive dye which is particularly useful for the labeling of antibodies after periodate oxidation. It also labels other carbonyl compounds (aldehydes and ketones), for example, many saccharides. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BP Fluor 647 maleimide is a thiol reactive bright green-fluorescent dye, it can be labeled to thiol containing biomolecules, such as primary antibody, secondary antibody, peptide, oligo, etc. The conjugates can be used as a probe for flow cytometry, immunocytochemical assays, including In-protein arrays, microscopy, tissue section imaging, in vivo imaging and optical probe development. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Coumarin 343 X carboxylic acid is a blue emitting fluorophore used as a laser dye. The fluorophore can serve as a FRET donor for FAM (fluorescein). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BP Fluor 488 acid is a powerful labeling dye. It will react with the amine group in antibody, proteins, peptides, amino-modified oligos, and other target molecules. The dye has an excitation peak at 499 nm and an emission peak at 520 nm. The conjugates are widely used in microscopy, flow cytometry, and other applications. BP Fluor 488 is a pure 5- sulfonated rhodamine molecule and it eliminates the lot-to-lot variation caused by two isomers ratio differences.
