摘要： 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. Systems and kits for practicing the subject methods are also provided.

摘要： An optical filter includes: an absorption layer including a first near-infrared absorbing dye (D1), a second near-infrared absorbing dye (D2), and a transparent resin; and a reflection layer including a dielectric multilayer film. The dye (D1) and the dye (D2) are squarylium compounds satisfying following (1) to (3). (1) The dye (D1) has a maximum absorption wavelength λmax(D1) within a range of 680 to 730 nm, and the difference between a wavelength at which a transmittance is 80% on the shorter wavelength side than λmax(D1) when the concentration is adjusted such that a transmittance at λmax(D1) is 10%, and λmax(D1) is 100 nm or less. (2) The dye (D2) has a maximum absorption wavelength λmax(D2) within a range of 720 to 770 nm. (3) A value obtained by subtracting λmax(D1) from λmax(D2) is 30 nm or more and 85 nm or less.

摘要： Water soluble light harvesting multichromophores having pendant chromophore groups are provided. The light harvesting multichromophore has a polymeric backbone including non-conjugated repeat units and a plurality of pendant donor chromophore groups linked to a non-conjugated repeat unit of the polymeric backbone. A pendant chromophore group can be a BODIPY group substituted with one or more water soluble groups. Polymeric tandem dyes based on the subject multichromophores are provided that further include an acceptor fluorophore linked to a non-conjugated repeat unit of the polymeric backbone and configured in energy-receiving proximity to a pendant donor chromophore group. Also provided are labelled specific binding members that include the subject polymeric tandem dyes. Methods of evaluating a sample for a target analyte and methods of labelling a target molecule in which the subject polymeric tandem dyes find use are provided. Systems and kits for practicing the subject methods are also provided.
