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.
摘要:
The present invention includes a method of allele-specific amplification, utilizing an allele-specific oligonucleotide, at least partially complementary to more than one variant of the target sequence, having a 3'-terminal nucleotide complementary to only one variant of the target sequence and having at least one nucleotide with a base covalently modified at the exocyclic amino group, wherein the allele-specific oligonucleotide is extended by a nucleotide-incorporating biocatalyst predominantly when hybridized to the variant of the target sequence for which it has said complementary 3'-terminal nucleotide.
摘要:
Methods, reaction mixtures and kits for detecting the presence or absence of a target nucleic acid variant from a selection of possible variants is described.
摘要:
The present invention provides a method for the amplification of at least a first and a second target nucleic acid that may be present in a fluid sample. The invention further provides a kit and an analytical system for carrying out said amplification.
摘要:
The present invention concerns the amplification of at least a first and a second target nucleic acid that may be present in at least one fluid sample using an internal control nucleic acid for qualitative and/or quantitative purposes.
