| Abstract | Conventional methods for detecting single nucleotide polymorphisms (SNPs), including direct DNA sequencing, pyrosequencing, and melting curve analysis, are to a great extent limited by their requirement for particular detection instruments. To overcome this limitation, we established a novel SNP detection technique utilizing multiple primer extension (MPEX) on a phospholipid polymer-coated surface. This technique is based on the development of a new plastic S-BIO® PrimeSurface® with a biocompatible polymer; its surface chemistry offers extraordinarily stable thermal properties, as well as chemical properties advantageous for enzymatic reactions on the surface. To visualize allele-specific PCR products on the surface, biotin-dUTP was incorporated into newly synthesized PCR products during the extension reaction. The products were ultimately detected by carrying out a colorimetric reaction with substrate solution containing 4-nitro-blue tetrazolium chloride (NBT) and 5-bromo-4-chloro-3-indolyl phosphate (BCIP). We demonstrated the significance of this novel SNP detection technique by analyzing representative SNPs on 4 LD blocks of the µ opioid receptor gene. We immobilized 20 allele-specific oligonucleotides on this substrate, and substantially reproduced the results previously obtained by other methods. |

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.
