Protein microarrays are mainly applied to protein function studies, screening the production of antibodies and recombinant proteins , discovery of proteins implicated in disease or those that are potential drug targets, rapid detection or diagnosis of disease (18,19) screening for protein–protein, DNA–protein and enzyme–substrate interactions (20,21). Previous … 3:35 Chemistry of Printed Nucleic Acid Microarrays Dr. Brian Ward, Principal Investigator Sigma-Aldrich Corporation Printing nucleic acids on glass microscope slides is a routine part of a microarray experiment. The track of nucleic acid greatly helped us study biological evolution, gene analysis, disease diagnosis, as well as drug discovery. Pharmaceutical companies have adopted high-data-capacity microarrays in drug discovery research for applications such as target identification, target validation and pathway analysis, compound profiling, and toxicology studies. They represent the next era of gene expression tools. Microarrays containing sequences representative of all human genes may soon permit the expression analysis of the entire human genome in a single reaction. Our comprehensive service includes assistance with sequence design, synthesis of standard or custom DNA/RNA (2’-OMe) aptamer microarrays, binding assays using binding molecules provided by you, such as proteins, nucleic acids, carbohydrates, or other kinds of small molecules. In the drug‐discovery process, microarrays have the potential to play a role in all stages, from new target discovery through compound profiling and safety assessment. The Role of Nanotechnology in Drug Discovery 16 April 2006 By Dr Amarpreet S Dhiman In terms of drug discovery and development, the role of nanotechnology currently lies in improving diagnostic methods, developing improved drug formulations and drug delivery systems for disease therapy. 1–10 This incredible molecule has many functions; however, its main role is the long-term storage of genetic information. Keywords: Multistranded DNA and RNA, alternative . Our understanding of RNA biology has also expanded tremendously, resulting in new approaches to engage RNA as a therapeutic target. September 2020 (First edition published by Informa in 2001, continuously updated and rewritten) The genetic information used in the growth and operation of living organisms is contained in DNA, a specific type of nucleic acid molecule. ... Nuclear acids including DNA and RNA play crucial roles in biological activities. PNA probes are known to be more efficient and selective in binding DNA sequences than the analogous oligonucleotides and are very suitable to be used for diagnostics in food. Perhaps the most crucial step in the use of molecular techniques for virus discovery is the efficient extraction of viral nucleic acid from the clinical specimen. genes, small interfering RNA (siRNA), and microRNA) are getting larger, there is an increasing need for further miniaturization and parallelization of cell-based assays. These studies have validated the use of microarrays in studying drug resistance in Leishmania and have pinpointed new genes overexpressed either by gene amplification or by other mechanisms. A number of studies in bacterial or mammalian cells have dealt with changes of expression in the presence of drugs ( 24 – 28 ) but few have dealt with the analysis of resistance per se . Recent observations indicate that each oligonucleotide is a unique entity, and small structural differences between oligonucleotides can often … DNA Microarrays in Herbal Drug Research Preeti Chavan, Kalpana Joshi and Bhushan Patwardhan Bioprospecting Laboratory, Interdisciplinary School of Health Sciences, University of Pune, Pune 411007, India Natural products are gaining increased applications in drug discovery and development.
