| Abstract | A new continuous cell line from ovarian tissue of commercial variety “Kolar Gold” of silkworm, Bombyx mori, was established and designated as DZNU-Bm-12. The tissue was grown in MGM-448 insect cell culture medium supplemented with 10% fetal bovine serum (FBS) and 3% heat-inactivated B. mori hemolymph at 25 ± 1°C. The migration of partially attached small round refractive cells from the fragments of ovarioles began from the beginning of explantation. The cells multiplied partially attached in the primary culture initially, and some of them become freely suspended after 20 passages. The cells were adapted to MGM-448 and TNM-FH media each with 10% FBS and the population doubling time of cell line was about 36 and 24 hr, respectively. The chromosome number was near diploid at initial passages and slightly increased at 176th passage, but a few tetraploids and hexaploids were also observed. DNA profiles using simple sequence repeat loci established the differences between DZNU-Bm-12 and DZNU-Bm-1 and most widely used Bm-5 and BmN cell lines. The cell line was found susceptible to B. mori nucleopolyhedrovirus (BmNPV) with 85–90% of the cells harboring BmNPV and having an average of 3–17 OBs/infected cell. We suggest the usefulness of this cell line in BmNPV-based baculoviral expression system and also for studying in vitro virus replication. |

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.
