| Abstract | Flagellar fragments are thin cylinders that are particularly suitable for the study of agglutination by electron microscopy. Their shape leads to a characteristic pattern of agglutination and thus the early stages can be studied. Measurement of interflagellar distances under conditions of negative staining, suggest that the minimum length of the rabbit antibody molecules is about 180 Å. The molecules carry the specific sites at the ends of the long axis, and become attached radially to the surface of the flagella, resembling the bristles of a bottle-brush. To explain this orientation it is postulated that the antibody is inserted into the surface of the flagellum in such a manner that surrounding molecules give it a fixed direction. Geometrically this hypothesis corresponds to an insertion into pits. Pepsin-treated (5S) rabbit antibody behaves in a like manner, but the molecule appears to be shorter. No information could be obtained about the thickness and actual shape of antibody molecules by the techniques employed. |

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.
