20180009990 · 2018-01-11 ·

Water solvated polymeric dyes and polymeric tandem dyes are provided. The polymeric dyes include a water solvated light harvesting multichromophore having a conjugated segment of aryl or heteroaryl co-monomers linked via covalent bonds, vinylene groups or ethynylene groups. The polymeric tandem dyes further include a signaling chromophore covalently linked to the multichromophore in energy-receiving proximity therewith. Also provided are labeled specific binding members that include the subject polymeric dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labeling a target molecule in which the subject polymeric dyes find use are also provided. Systems and kits for practicing the subject methods are also provided.

Deep Ultraviolet-Excitable Water-Solvated Polymeric Dyes

Water solvated polymeric dyes having a deep ultraviolet excitation spectrum are provided. The subject polymeric dyes include a light harvesting multichromophore having conjugation-modifying repeat units incorporated into the polymer backbone to provide segments of π-conjugated co-monomers having limited π-conjugation between segments. Polymeric tandem dyes are also provided that further include a signaling chromophore covalently linked to the multichromophore in energy-receiving proximity therewith. Also provided are labelled specific binding members that include the subject water solvated polymeric dyes. Methods of evaluating a sample for the presence of a target analyte and methods of labelling a target molecule in which the subject polymeric dyes find use are also provided.

20220348770 · 2022-11-03 ·

Water-soluble dipyrromethene-based dyes are provided herein. In certain cases, the water-soluble dye is a dipyrromethene-boron dye. Embodiments of the subject water-soluble dipyrromethene-based dyes have a narrow absorption maxima in the yellow green range close to or at the 561 nm laser line, and are suitable for use in tandem dye systems. Embodiments of the subject dyes efficiently transfer energy to an acceptor chromophore while a second dipyrromethene-based dye of the same or different chemical structure is within energy-receiving proximity therewith. Also provided herein are tandem dyes that include the subject water-soluble dipyrromethene-based dyes, e.g., as donor chromophores. Methods of evaluating a sample for the presence of a target analyte and methods of labelling a target molecule in which the subject dyes find use are also provided. Systems and kits for practicing the subject methods are also provided.
