Title:
FLUORESCENT CELLULOSE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2023/089972
Kind Code:
A1
Abstract:
The present invention provides fluorescent cellulose microparticles which are capable of reducing deployment failure by improving the deployability during deployment in immunochromatography, while maintaining sufficient color developability and dispersion stability if used for immunochromatography. The present invention relates to: fluorescent cellulose particles, each of which contains a cellulose particle, a fluorescent dye compound and a heterocyclic compound represented by general formula (1) (wherein R1 represents a functional group that has an affinity for a biological substance; and R2 represents an ether bond part bonded to the cellulose particle), and which are characterized in that, per 1 g of the fluorescent cellulose particles, the content of the cellulose particles is 30% by mass to 90% by mass, the content of the fluorescent dye compound is 1% by mass to 40% by mass, and the content of the heterocyclic compound is 3% by mass to 50% by mass; and a diagnostic agent and an immunochromatography kit, each of which comprises the fluorescent cellulose particles.
