| Abstract | Dissociated cell cultures of the rodent hippocampus have become a standard model for studying many facets of neural development. The cultures are quite homogeneous and it is relatively easy to express green fluorescent protein (GFP)-tagged proteins by transfection. Studying developmental processes that occur over many hours or days--for example, dendritic branching--involves capturing images of a cell at regular intervals without compromising cell survival. This approach is also useful for studying events of short duration that occur asynchronously across the cell population. For such studies, it is highly desirable to use a computer-controlled microscope with an automated stage, to follow multiple cells at different locations in the culture, moving sequentially from one to the next and capturing an image at each location. A method to correct for focal drift is also required. For long-term imaging, we culture neurons in a medium without phenol red, which is thought to give rise to toxic substances following exposure to light. To label cells with GFP-tagged proteins for long-term imaging, we usually use nucleofection (rather than lipid-mediated transfection); this gives a high transfection efficiency, which makes it easier to find the right cell for imaging. Our protocol for long-term imaging is given here, along with appropriate methods to express GFP-tagged proteins. Examples illustrate how the protocol can be used to image cytoskeletal dynamics during axon specification and to study kinesin motor dynamics in stage 2 neurons (when minor neurites extend). |

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.
