Maleimide derivative of boron-dipyrromethene dye BDP 558/568, which emits fluorescence in the yellow range; BDP 558/568 maleimide can be used for modification of thiol groups in biomolecules.

NHS ester derivative of BDP 581/591 borondipyrromethene fluorophore for the labeling of proteins, peptides, and other biomolecules. The dye is useful for fluorescence polarization and two-photon experiments, and as a ROS probe.

A bifunctional reagent containing the azide group and hydrazide function. It reacts with aldehydes and ketones. The azide group can then be coupled with various alkynes via CuAAC reaction.

Azide-PEG4-OH is a bifunctional molecule with an azide group, primary alcohol, and a hydrophilic PEG4 linker in between.

A hydrophilic bifunctional linker with azide and NHS ester function groups flanking PEG6 (hexaethylene glycol).

Water-soluble heterobifunctional crosslinker with a primary hydroxyl group, alkyne-reactive azide group, and a PEG6 hydrophilic linker.

Activated NHS ester for azido-labeling of peptides and proteins.

Cell-permeable acetoxymethyl ester (AM) form of BAPTA, a highly selective calcium chelator for cell signaling studies.

A cell-permeant, dual-excitation ratiometric fluorescent indicator for measuring the intracellular pH.

BDP 493/503 is a lipophilic green fluorescent dye for the staining and tracing of cell membranes, lipids, and oils.
