Fluorescent Labeling
The availability of new fluorophores has dramatically changed the possibilities for the sensitive detection of biomolecules and the analysis of their interactions. Improved fluorescent dyes are now enabling previously impossible studies of cellular structures and cellular processes. PromoKine provides a wide range of high-quality fluorophores for fluorescent labeling of diverse biomolecules: protein labeling, antibody labeling, nucleic acid labeling (DNA labeling, RNA labeling), as well as complete labeling kits and ready-to-use fluorescent conjugates.
Our PromoFluor dyes are cost-effective alternatives to well-known, leading fluorophores and span the wavelengths spectrum from blue to far red. They show an outstanding fluorescence intensity and photostability, a strong light absorption, high fluorescence quantum yield and good water solubility and can be used for fluorescence microscopy, fluorescent in situ hybridization (FISH), fluorescence correlation spectroscopy (FCS) and microarrays (protein, DNA). Some of them offer an extra large Stokes shift, which makes them ideally suited for multicolor labeling or flow cytometry applications. PromoFluor dyes are available e.g. as NHS esters and maleimides ready for covalent coupling or as conjugates with biotin, streptavidin, phalloidin, deoxynucleotides and secondary antibodies. Moreover, we also provide high-quality protein and antibody labeling kits with different PromoFluor dyes and other common fluorescent labels such as FITC, rhodamine, sulforhodamine or phycoerythrins.
In addition, PromoKine offers Phycobiliprotein dyes with high stability and bright fluorescence (R-phycoerythrin, B-phycoerythrin, Allophycocyanin) for coupling to biomolecules.
