| Abstract | Human T-cell leukemia virus type I (HTLV-I) provirus DNA from the cultured cell line HUT 102 and from peripheral mononuclear cells (PBMC) of anti-HTLV-I antibody-positive Japanese blood donors was detected by the nested double polymerase chain reaction (PCR) method. This procedure consists of a first amplification and a second amplification with the products of the first amplification and primers interior to the first primers. Using this method, we demonstrated that it is possible to detect single-template DNA. Polyacrylamide gel electrophoresis of the nested double PCR products, with our primers, revealed three bands with excess amounts of template DNA, two bands with moderate amounts, and a single band with limited amounts. The amount of provirus in PBMC was roughly estimated from the results of the nested double PCR. Particle agglutination (PA) assays and indirect immunofluorescence testing (IF) with mixed MT-2 cells and Molt-4 cells as targets to detect anti-HTLV-I antibody were performed, and the results were compared with those of the nested double PCR of the pX region. None of the 101 PA-negative samples were positive in either the IF or PCR test. Of the 155 samples that were antibody positive by the PA assay, 57 were positive by both PCR and IF. Furthermore, the results of the IF and PCR tests coincided completely. It was therefore concluded that the IF method is most appropriate for confirmation of the PA assay currently used in most diagnostic laboratories and blood centers. |

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.
