(+)-JQ-1-PEG4-Amine, TFA salt features an amino (NH2) group reactive with activated NHS esters or carboxylic acids in the presence of EDC or HATU. It includes (+)-JQ-1, a potent, specific, and reversible pan-BET family inhibitor useful for studying BET bromodomains in oncogenesis. The PEG4 linker adds water solubility to the compound.
Fluorescein-PEG4-DBCO is a xanthene dye containing a reactive DBCO group and a hydrophilic PEG spacer arm with excitation/emission maximum of 494/517 nm. DBCO reacts with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalysts. It could be used as a quantum yield standard. Hydrophilic 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.
Fluorescein-PEG4-Mal is a xanthene dye containing a maleimide group, which selectively reacts with free thiol, sulfhydryl, or mercapto group via Michael addition to form a stable carbon sulfur bond.
