Analysis of Haemophilus Somnus by Real-Time PCR Method (CAT#: STEM-MB-2986-LGZ)

Introduction

Haemophilus somnus is a small, rod-shaped, gram-negative pleomorphic coccobacillus, (derived from the word cocci meaning “spherical shaped” and bacilli meaning “elongated”), with gram stain morphology similar to other species in this genus (as well as other genera of family Pasteurellaceae) .<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.
