1. A method of treating a nucleic acid fiber immobilized to a solid support comprising:
- a) providing;
i) a stretched nucleic acid fiber having a sequence immobilized to a solid support; and
ii) one or more labeled probes containing sequences essentially complementary to said sequence of said immobilized nucleic acid fiber;
b) reacting said immobilized nucleic acid fiber with said probes under conditions wherein said probes are capable of binding to essentially complementary sequences present on said nucleic acid fiber and wherein no substantial background is produced; and
c) detecting the presence of probes bound to said nucleic acid fiber.

11. A method for the stretching of a nucleic acid molecule, comprising:
-
a) providing; i) a first solid support treated with 3-aminopropyltriethoxysilane; ii) a solution comprising a nucleic acid molecule; and iii) a second solid support; and b) placing an aliquot of said solution comprising said nucleic acid molecule onto said first solid support; c) placing said second solid support on top of said aliquot of said solution to cover said solution; and d) allowing said solution to dry whereby said nucleic acid molecule is uniformly stretched to a dimension of approximately 2.3 kilobases per micrometer. - View Dependent Claims (12, 13)
