چکیده

A simple mass spectrometric based assay, the PinPoint assay, has previously been described for typing single nucleotide polymorphisms. The identity of a polymorphism is determined by mass differences of single base extended genotyping primers as determined by MALDI-TOF mass spectrometry. A simple method for multiplexing the assay is described, employing multiple primers with 5'oligo(dT) sequences (MassTags) which serve to mass discriminate the peaks of multiple extended and non-extended primers. The assay is extremely rapid and requires no labeling reagents.

Detection of tick-borne pathogens by MassTag polymerase chain reaction.

MassTag polymerase chain reaction (PCR) is a platform that enables microbe detection using primers labeled through a photocleavable link with tags that vary in molecular weight. After multiplex PCR, tags are released by ultraviolet irradiation and analyzed by mass spectroscopy. The identification of a microbe in a sample is determined by its cognate tags. Here we describe establishment and impl...

Genotyping individual amphimedon embryos, larvae, and adults.

INTRODUCTIONThe distribution of Amphimedon queenslandica is patchy on coral reefs in the Great Barrier Reef, with small, localized populations detected in shallow, still water reef-flat environments. A. queenslandica is a spermcast spawner, in which fertilization occurs internally. Sperm presumably originate from neighboring reproductive individuals within the population. The ability to genotyp...

Comparison of Two Multiplex PCR Systems for Meat Species Authentication

Background: Meat species adulteration has become a problem of concern. This study aimed to compare two previously published multiplex Polymerase Chain Reaction (PCR) methods for meat species authentication.  Methods: The primers used in the first multiplex PCR involved species-specific reverse primer for sheep, goat, cattle, pig, and donkey with universal forward primer. In the second multiple...

Bead-based multiplex genotyping of human papillomaviruses.

Typing of human papillomaviruses (HPV) by DNA hybridization procedures, such as reverse line blot (RLB) assay, is sensitive and well validated. However, the application of these assays to high-throughput analyses is limited. Here, we describe the development of multiplex human papillomavirus genotyping (MPG), a quantitative and sensitive high-throughput procedure for the identification of multi...

Multiplex MassTag-PCR for respiratory pathogens in pediatric nasopharyngeal washes negative by conventional diagnostic testing shows a high prevalence of viruses belonging to a newly recognized rhinovirus clade.

BACKGROUND Respiratory infections are the most common infectious diseases in humans worldwide and are a leading cause of death in children less than 5 years of age. OBJECTIVES Identify candidate pathogens in pediatric patients with unexplained respiratory disease. STUDY DESIGN Forty-four nasopharyngeal washes collected during the 2004-2005 winter season from pediatric patients with respirat...
