| Abstract | A highly versatile system for genetic, biochemical, and immunological analysis of human cell surface components has been developed using a human-Chinese hamster somatic cell hybrid containing chromosome 11 as its only human chromosome. This system lends itself to studies such as identification of human cell surface antigens and other genetic markers, regional gene mapping of these markers on chromosome 11, mutational analysis of these markers, and exploration of distribution of these antigens in normal and pathological human tissues. Genetic analysis of a1, one of the human antigens expressed by this hybrid, has been accomplished by subjecting a series of a1- variants to complementation analysis. These experiments have shown that the a1- variants behave in a recessive manner and that at least four genes, including three Chinese hamster genes, are needed for a1 antigen expression. Biochemical analysis has shown that a macroglycolipid isolated from human erythrocytes contains the a1 antigenic activity, so that genes coding for glycosyltransferases are required for its biosynthesis and may correspond to the complementation groups identified. The power of combined genetic, biochemical, and immunological approaches to understanding cell membrane molecules is demonstrated. |

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.
