Fluorescent Label

Fluorescent labeling techniques can conjugate fluorescent dyes to biomacromolecules like proteins and antibodies through amine, thiol or click chemistry functional groups, enabling their visualization and functional analysis. These techniques are widely applied in immunoimaging and in vitro functional studies.The fluorescent stock solutions are easy to use with minimized reagent loss, while ensuring experimental reproducibility.
