摘要:
Disclosed is an in vitro process for synthesizing DNA encoding a family of antigen-combining proteins. This process involves obtaining DNA containing genes encoding antigen-combining proteins and then combining these genes with sequence specific primers. These primers can be oligonucleotides homologous to conserved regions of the genes. The genes and primers are then subjected to sequence specific gene amplification.
摘要:
A method of producing libraries of genes encoding antigen-combining molecules or antibodies is described. In addition, a method of producing antigen-combining molecules which does not require an in vivo procedure is described. Vectors useful in the present method and antigen-combining molecules produced by the method are discussed. The antigen-combining molecules are useful for the detection, quantitation, purification and neutralization of antigens, as well as for diagnostic, therapeutic and prophylactic purposes.

摘要:
The invention encompasses methods for enriching for and identifying a polymorphism within a nucleic acid sample either by separating a subset of a nucleic acid sample or by selectively replicating a subset of a nucleic acid sample such that the polymorphism is contained within a nucleic acid population with reduced complexity, and then identifying the polymorphism within the enriched nucleic acid sample. Methods also are disclosed for enriching for and identifying a polymorphism by contacting a nucleic acid sample that includes a subset of nucleic acid molecules having a sequence that binds to a sequence-specific binding activity with a molecule having a sequence-specific binding activity under conditions which permit specific binding, such that the subset of nucleic acid molecules bound to the activity is enriched for nucleic acid molecules having the sequence recognized by the sequence-specific binding activity, and detecting a polymorphism with respect to a reference sequence in the subset of nucleic acid molecules.

摘要:
The invention features a novel isolated Family B DNA polymerase, a Thermococcus polymerase JDF-3, and mutant recombinant forms thereof. Mutant polymerases of the invention are deficient in 3′ to 5′ exonuclease activity and/or exhibit reduced discrimination against non-conventional nucleotides relative to the wild-type form of the polymerase.
摘要:
The invention relates to a method of generating a signal indicative of the presence of a target nucleic acid in a sample, where the method includes forming a cleavage structure by incubating a sample comprising a target nucleic acid with a probe having a secondary structure that changes upon binding of the probe to the target nucleic acid and further comprising a binding moiety. The invention also includes the steps of cleaving the cleavage structure with a nuclease to release a nucleic acid fragment to generate a signal, wherein generation of the signal is indicative of the presence of a target nucleic acid in a sample, and detecting and/or measuring the amount of the fragment captured by binding of a binding moiety to a capture element on a solid support.The invention also relates to a method of detecting or measuring a target nucleic acid in a sample, where the method includes forming a cleavage structure by incubating a sample containing a target nucleic acid with a probe having a secondary structure that changes upon binding of the probe to a target nucleic acid and comprising a binding moiety, and cleaving the cleavage structure with a nuclease to generate a cleaved nucleic acid fragment and detecting and/or measuring the amount of the fragment captured by binding of a binding moiety to a capture element on a solid support.
