PromoFluor-670, PromoFluor-680, PromoFluor-700, PromoFluor-750, PromoFluor-770, PromoFluor-780 and PromoFluor-840 are next-generation long wavelength dyes representing a true breakthrough in the field. Other near-IR dyes suffer from problems of limited fluorescence brightness due to excessive dye aggregation and poor stability. The high water solubility of PromoFluor dyes means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates. PromoFluor NIR dyes are superior alternatives to the respective Alexa Fluor near-infrared dyes.
PromoFluor Amino-Modified Labels are intended for the covalent labeling of biomolecules containing a carboxy group e.g., glycoproteins. The amino group of PromoFluor Amino-Modified Labels can be cross-coupled to carboxy groups through a mild in situ activation.
