| Abstract | The genome of human T-cell lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV), the infectious agent etiologically associated with the acquired immunodeficiency syndrome, contains, in addition to the genes for the polymerase, core, and envelope proteins, several open reading frames. To investigate whether the 3' open reading frame (3' orf) located between the envelope gene and the 3' long terminal repeat is a gene expressed in vivo in infected individuals, we inserted a fragment of 3' orf in a prokaryotic expression vector. The protein product synthesized in bacteria was purified and allowed to react with sera from individuals infected with human T-cell lymphotropic virus type III as indicated by seropositivity for other viral proteins. Two-thirds of the sera, regardless of the clinical status of the individuals, reacted with the purified protein indicating that 3' orf is a viral gene the product of which is immunogenic in vivo. A polyclonal rabbit antiserum reacting against the 3' orf gene product was obtained by serial injection of rabbits with the purified bacterial protein. The antiserum recognized a 27-kDa protein in the human T-cell lymphotropic virus type III-infected lymphocytes. |

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.
