Analysis of Nocardia Brasiliensis by Real-Time PCR Method (CAT#: STEM-MB-3320-LGZ)

Introduction

Nocardia is a genus of aerobic, gram-positive bacilli found in the soil and distributed throughout the world. The most common pathogen is Nocardia asteroides, which accounts for approximately 80% of pulmonary infections; less common pathogens are Nocardia brasiliensis and Nocardia otitidiscaviarum.<br />A real-time polymerase chain reaction (real-time PCR, or qPCR) is a laboratory technique of molecular biology based on the polymerase chain reaction(PCR). It monitors the amplification of a targeted DNA molecule during the PCR(i.e.,in real time), not at its end, as in conventional PCR.<br />Two common methods for the detection of PCR products in real-time PCR are(1)non-specific fluorescent dyes that intercalate with any double-stranded DNA and (2)sequence-specific DNA probes consisting of oligonucleotides that are labelled with a fluorescent reporter, which permits detection only after hybridization of the probe with its complementary sequence.
