Various molecular biology techniques have become available in the last few years. One of the most revolutionary of these techniques regarding nucleic acid analysis is the polymerase chain reaction (PCR), which was first described in 1985. This method relies on the exponential amplification of specific DNA fragments, resulting in millions of copies that can serve as templates for different kinds...

The aim of this study was to produce a sensitive, simple and rapid diagnostic method for the detection of foot-and-mouth disease virus (FMDV) in suspected cases of FMD, a one-step single-tube method of reverse transcription loop-mediated isothermal polymerase amplification (RT-LAMP). A set of six common primers was designed to target the highly conserved region of the RNA polymerase 3Dpol gene ...

avian influenza (ai) is a viral respiratory disease of domestic and wild birds. in the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. cloacal swabs collected from chickens experimentally infected with h9 subtype ai virus, used in a reverse transcription-polymerase chain reaction (rt-pcr) assay for detection of ai. in infected animals, ai...

OBJECTIVE Molecular cloning and bioinformatics analysis of annexin A2 (ANXA2) gene in sika deer antler tip were conducted. The role of ANXA2 gene in the growth and development of the antler were analyzed initially. METHODS The reverse transcriptase polymerase chain reaction (RT-PCR) was used to clone the cDNA sequence of the ANXA2 gene from antler tip of sika deer (Cervus Nippon hortulorum) a...

Currently, a variety of tests are used to detect bovine viral diarrhea virus (BVDV) in persistently infected (PI) cattle. These tests include immunohistochemical staining (IHC), antigen capture enzyme-linked immunosorbent assay (ACE), virus isolation (VI), and reverse transcription-polymerase chain reaction (RT-PCR). However, a lack of methods standardization could compromise the ability to con...

Zika virus (ZIKV) has gained global attention as an etiologic agent of fetal microcephaly and Guillain-Barré syndrome. Existing immuno-based rapid tests often fail to distinguish between Zika and related flaviviruses that are common in affected regions of Central and South Americas and the Caribbean. The US CDC and qualified state health department laboratories can perform the reverse transcrip...

Background Noroviruses are a group of viruses that cause gastroenteritis (illness that usually includes diarrhea and/or vomiting) in people. Gastroenteritis means inflammation of the stomach and small and large intestines. Many different viruses can cause gastroenteritis, including rotaviruses; noroviruses; adenoviruses, types 40 and 41; sapoviruses; and astroviruses. Current techniques used fo...

We have attempted a fine characterization of the angiogenic response induced by multiple myeloma endothelial cells (MMEC) by using the chick embryo chorioallantoic membrane (CAM) assay and by reverse transcriptase-polymerase chain reaction (RT-PCR). Results showed that in the CAM assay MMEC induced an angiogenic response comparable to that of a well-known angiogenic cytokine, namely fibroblast ...
