Labeling Chemistry Selection Tool

Welcome to the Labeling Chemistry Selection Tool featuring Molecular Probes® reagents and labeling technologies! Quickly find the best reactive dye or label for your experiment. Whether you are labeling proteins and antibodies for immunofluorescence, nucleic acids for in situ hybridization, or lipids for membrane studies, this tool will help you find the right conjugation product.

Here are a few definitions to help you get started:

Reactivity - this filter refers to the chemical group on the molecule you want to label (i.e. your antibody, protein or DNA)

Reactive Moiety - this filter refers to the chemical group on the dye or label you want to attach to your molecule (i.e fluorescein isothiocyanate, Alexa Fluor® 488 malemide)
