  • Patent number: 11618825
    Abstract: The present invention relates generally to novel rhodamine dyes which upon conjugation with another molecule form single isomeric conjugation products. These novel rhodamine dyes contain only one single functional group on the rhodomine molecule for conjugation so that their conjugation products are single isomeric conjugation products.

  • Publication number: 20220219141
    Abstract: The invention discloses method for manufacturing agar or agarose beads, comprising the steps of: a) providing a water phase comprising an aqueous solution of agar or agarose at a temperature of 40-100° C.: b) providing an oil phase comprising a water-immiscible solvent and an emulsifier at a temperature of 40-100° C.; c) emulsifying the water phase in the oil phase to form a water-in-oil emulsion: d) cooling the water-in-oil emulsion to a temperature below a gelation temperature of the agar or agarose to form a dispersion of solidified agar or agarose beads: and c) recovering agar or agarose beads from dispersion, wherein the emulsifier comprises a phosphate ester of an alkoxy lated fatty alcohol.
