An in vitro target amplification-based nucleic acid probe
test that detects HCV RNA in human plasma and serum utilizing Transcription-Mediated Amplification (TMA).
Policar noted that nucleic acid probe
tests are not as accurate as the NAATs, and clinicians using these tests should consider switching to a NAAT system.
The broadly claimed methods result in a substantial reduction in the non-specific signal in the assay as compared with conventional nucleic acid probe
based hybridization assays to thereby improve the performance of the probe based assays far beyond that obtainable by mere optimization of stringency conditions.
patent application, among other uses, covers compositions and processes for trapping nucleic acid on solid supports, a process used in the majority of nucleic acid probe
test now being performed.
The nucleic acid probe
test for vaginal infection, which was removed from the market following the study, performed better than did clinicians' microscopic tests.
Part One covers general and basic techniques, and includes such subjects as rapid methods and automation, testing and use of the results, sample removal and preparation, enumeration, evaluation of microflora by nonmicrological methods, identification, applications of immunology, using nucleic acid probe
hybridization and prediction of product lifespan.
Another format uses a nucleic acid probe
specific to Listeria to identify any of those organisms present after enrichment by using chemicals that become colored only in the presence of the bacteria.
Our recent findings suggest that up to ten times more of nucleic acid probe
can be loaded onto proprietary silane surfaces compared to other methodologies such as the avidin-biotin system or common silanes, while still retaining a monolayer-like structure.
There are now sets of codes for direct nucleic acid probe
, amplified nucleic acid probe
, and quant ification by nucleic acid probe
for 22 different organisms including mycoplasma, viruses, and Chlamydia spp.
ORIGEN provides uniform assay formats to conduct a multitude of diagnostic tests including immunoassay, nucleic acid probe
, and clinical chemistry tests.
The section referred to is a paragraph on page 2024, in which we collectively describe conventional nucleic acid probe
techniques as being of "limited utility owing to poor sensitivity".
Nonetheless, nucleic acid probe
technology is already in the lab and will play an increasingly important role as it is applied to more diseases.
