摘要:
The present invention provides reaction mixtures that include blocked oligonucleotides comprising 2'-terminator nucleotides. The blocked oligonucleotides are rendered extendible when the 2'-terminator nucleotides are removed from the oligonucleotides, e.g., via pyrophosphorolysis. The reaction mixtures can be used in various nucleic acid polymerization and/or amplification assays, among many other applications. In addition to reaction mixtures, the invention also provides related methods and reaction mixtures.

摘要:
Alkyl amines act to release formaldehyde cross-linking that occurs in biological samples. Thus, contacting alkyl amines to formaldehyde fixed samples is a useful way to render biological components of the samples, including nucleic acids or proteins, more accessible to detection and characterization.
