AMCA-PEG4-acid is a fluroescent reagent with a terminal carboxylic acid group. The hydrophilic PEG spacer arm increases water solubility, membrane permability, and conjugation efficiency. AMCA-PEG4-acid is a popular blue fluorescent tagging molecule that has a maximal absorption of 345 nm and emission at 450 nm. The terminal carboxylic acid can react with primary amine groups of activated NHS ester to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

nonadeca-1,18-dien-10-ol

BDP FL-PEG8-NHS ester is a BDP dye linker containing a NHS ester group and a hydrophilic PEG spacer arm. The NHS ester allows the dye to react with primary amines and the hydrophilic PEG spacer arm increases water solubility as well as membrane permability. This dye is used for protein and peptide labeing and is photostable. BDP FL-PEG8-NHS ester is a green-fluorescent dye and 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.

Bromoacetamido-PEG12-Tris(-PEG11-bromoacetamide) functions as a branched PEG linker, where the terminal bromo groups are good leaving groups for nucleophilic substitution reactions. The PEG links raise the solubility of the molecule in aqueous media and assist in optimizing DMPK properties. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PC-PEG3-biotin functions as a biotinylating reagent featuring a photocleavable moiety and terminal biotin which can react with amine molecules in the presence of activators like EDC or HATU. This structure allows for efficient photorelease of linked molecules, typically achieving over 90% cleavage in 5-25 minutes using a near-UV lamp. The PEG3 spacer imparts hydrophilicity.
