Illustrated is the preparation and expression of manufactured genes capable of directing synthesis of human immune and leukocyte interferons and of other biologically active proteinaceous products, which products differ from naturally-occurring forms in terms of the identity and/or relative position of one or more amino acids, and in terms of one or more biological and pharmacological properties but which substantially retain other such properties.

Manufacture and expression of large structural genes

The present invention provides an efficient and economical method for reducing carryover contamination in an amplification procedure. The method of the present invention enables background caused by contaminant amplification product to be reduced or eliminated through the incorporation of at least one modification into the amplification product. The modified amplification product is readily distinguishable from the target sequence in a test sample. Prior to amplifying the target in a new test sample, the sample may be treated to selectively eliminate the contaminant amplification product so that it cannot be amplified in the new sample.

Method for reducing carryover contamination in an amplification procedure

A method and a kit for the isolation and quantitative detection of a selected target nucleic acid sequence from solution employing two probes. A first probe is complementary to one portion of the target and is covalently attached to a first complexing agent (e.g., either an antigen or an antibody). The second probe is complementary to a different portion of the target and is associated with a reporter group. Following hybridization of the target and two probes in solution, a solid support coated with a second complexing agent (i.e., a corresponding antibody or antigen) capable of binding to the first complexing agent on the first probe is employed to immobilize the target-probe hybrid complex. A plurality of types of first probes may be used. Each type is attached to the same sort of complexing agent but each includes a nucleic acid sequence which is complementary to a different portion of the target.
