| Abstract | A potent growth-promoting polypeptide, the prostate-derived growth factor (PrDGF), has been purified to apparent homogeneity from acid extracts of rat prostatic tissue using ion-exchange, reverse-phase, and gel-permeation chromatography. PrDGF migrates as a single protein-staining band in NaDodSO4/PAGE in precise correspondence to extractable PrDGF activity in nonstained NaDodSO4 gels. PrDGF is acid- and heat-stable but is sensitive to reduction or protease treatment. PrDGF is an acidic (pI 5.0) protein of approximately equal to 25 kDa in NaDodSO4/polyacrylamide gels and of approximately equal to 6-8 kDa in reduced NaDodSO4/polyacrylamide gels. PrDGF stimulates the linear incorporation of [methyl-3H]thymidine into normal rat kidney cells between 0 and 16 ng/ml. PrDGF appears to differ from other known growth factors in chemical composition and biological properties, suggesting that PrDGF is a previously undescribed growth factor. |

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.
