| Abstract | The relevance of RNA in many biological functions has been recognized, broadening the scope of RNA research activities, from basic to applied sciences, also aiming the translation to clinical fields. The preparation and purification of RNA is a critical step for further application, since the quality of the template is crucial to ensure reproducibility and biological relevance. Therefore, the establishment of new tools that allows the isolation of pure RNA with high quality is of particular importance. New chromatographic strategies for RNA purification were considered, exploiting affinity interactions between amino acids and nucleic acids. In the present study, a single arginine-affinity chromatography step was employed for the purification of RNA from a total eukaryotic nucleic acid extract, thus eliminating several steps compared with current RNA isolation procedures. The application of this process resulted in a high RNA recovery yield of 96 ± 17% and the quality control analysis revealed a high integrity (28S:18S ratio = 1.96) in RNA preparations as well as a good purity, demonstrated by the scarce detection of proteins and the reduction on genomic DNA contamination to residual concentrations. Furthermore, the performance of the new RNA isolation method was tested regarding the applicability of the isolated RNA in modern molecular biology techniques. Hence, this new affinity approach will simplify the isolation and purification of RNA, which can bring great improvements in biomedical investigation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
