Patent number: 6514295Abstract: An improved method of making a series of bead or microsphere or particle populations characterized by subtle variation in a proportion or ratio of at least two fluorescent dyes distributed within a single bead of each population is provided. These beads, when excited by a single excitation light source are capable of giving off several fluorescent signals simultaneously. A set containing as many as 64 distinct populations of multicolored, fluorescent beads is provided and when combined with analytical reagents bound to the surface of such beads is extremely useful for multiplexed analysis of a plurality of analytes in a single sample. Thus, methods of staining polymeric particles, the particles themselves, and methods of using such particles are claimed.Type: GrantFiled: April 13, 1999Date of Patent: February 4, 2003Assignee: Luminex CorporationInventors: Don J. Chandler, Beth A. Lambert, Janet J. Reber, Stacie L. Phipps

Patent number: 6491731Abstract: A mixture of yellow azo- and azoxystilbene dyes having the shade of a C.I. Direct Yellow 11 dye is obtainable from the self-condensation of 4,4′-dinitro-2,2′-stilbenedisulfonic acid in the presence of an alkali metal hydroxide and an excess of formaldehyde beyond that needed for the conversion of 4,4′dinitro-2,2′-stilbenedisulfonic acid to Direct Yellow 6. Concentrated aqueous solutions of the dyes are obtainable by converting the sparingly soluble alkali metal salt of the dye into a water-soluble alkanolammonium salt by a double cation exchange via a lipophilic ammonium salt, in which process the double ion exchange is carried out in a two-phase system of methyl isobutyl ketone/water and using, for the first ion exchange a trialkylamine containing a total of 12 to 40 carbon atoms and, for the second ion exchange, a mono-, di- or trialkanolamine containing 2 to 4 carbon atoms in each alkyl moiety. The dyes are especially useful for dyeing paper.Type: GrantFiled: May 25, 2000Date of Patent: December 10, 2002Assignee: Ciba Specialty Chemicals CorporationInventor: Frederick Harold Gouzoules
