| Abstract | INTRODUCTIONThis protocol describes the use of lentiviral vectors to deliver small interfering RNA (siRNA)-mediated silencing cassettes. The combination of these two technologies allows for the development of a powerful tool to achieve long-term down-regulation of specific target genes both in vitro and in vivo. It combines the specificity of RNA interference with the versatility of lentiviral vectors to stably transduce a wide range of cell types. In this method, a small hairpin (shRNA) is cloned initially into an entry vector (pENTR/U6) immediately downstream from an hU6 promoter. The silencing cassette is flanked by recombination sites from bacteriophage λ (attL1 and attL2). Once an effective shRNA is obtained, it can be transferred to the destination vector. The destination vector is a lentiviral vector carrying a marker (green fluorescent protein [GFP] or a selection marker) with a destination cassette cloned upstream of the marker (attR1 and attR2 flanking a ccdB toxic gene). Thus, the silencing cassette can be transferred from the entry vector to the destination vector in a simple Gateway LR cloning reaction. The positioning of the silencing cassette upstream of the marker expression cassette avoids down-regulation of the marker. |

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.
