Methods and Compositions For Sorting and/or Determining Organisms
This invention is directed to methods and compositions for sorting and/or determining microscopic organisms or cells. The methods and compositions are directed to the use of molecular probes to selectively stain the organisms or cells in combination with the use of binding partners to selectively immobilize the stained organisms or cells to a solid carrier. By combining the selectivity of both molecular probes and binding partners in an orthogonal method for staining and immobilization, these methods and compositions increase both the discriminating power of the assays and/or the certainty of the result obtained therefrom.

51 . A composition comprising:
one or more organisms stained with one or more detectable molecular probes; and
a solid carrier to which is immobilized a binding partner,
wherein the one or more stained organisms are linked to the solid carrier through the interaction of the organism and its binding partner.
52 . The composition of claim 51 , wherein the binding partner is an antibody and the organism is the antigen to the antibody.
53 . The composition of claim 51 , wherein the solid carrier is a solid carrier array comprising antibodies to a plurality of different organisms of interest which have each been immobilized at unique identifiable locations on the array.
54 . The composition of claim 51 , wherein the solid carrier is a coded beaded support.
55 . The composition of claim 51 , wherein the solid carrier is a microscope slide.
56 . A composition comprising:
two or more different organisms of interest that are detectably or independently stained with one or more molecular probes; and
a mixture of two or more different types of coded beaded supports,
wherein to each different type of coded beaded support has been immobilized a different binding partner that is selected to detect a particular organism of interest and wherein the different detectable or independently detectable organisms are selectively bound to the coded beaded supports as a result of the occurrence of specific binding interactions of the binding partner and the organisms.
57 . The composition of claim 56 , wherein the binding partner is an antibody and the organism is the antigen to the antibody.
58 . A composition comprising:
two or more different organisms of interest that are detectably or independently stained with one or more molecular probes; and
a solid carrier array to which binding partners have been immobilized at unique identifiable locations such that the detectably or independently stained organisms are selectively bound to the locations on the array as a result of the occurrence of specific binding partner interactions.
59 . The composition of claim 58 , wherein the binding partner is an antibody and the organism is the antigen to the antibody.
