| Abstract | We are presenting the first method for identification and quantification of antibiotic derivatives in honey samples using regenerable antigen microarrays in combination with an automated flow injection system. The scheme is based on an indirect competitive immunoassay format using monoclonal antibodies bound to the surface of the microarray. The surface of glass slides was coated with epoxy-activated poly(ethylene glycol) and enables direct immobilization of the antibiotic derivatives. The antigen/antibody interaction on the surface of the chip can be detected by chemiluminescence (CL) read-out via CCD camera. The method allows for fast analysis of the four analytes simultaneously and without purification or extraction. An effective data evaluation method also was developed to warrant unambiguous identification of the spots and to establish grey levels of CL intensities. The software developed enables fast and automated processing of the CL images. Dose–response curves were obtained for the derivatives of enrofloxacin, sulfadiazine, sulfamethazine and streptomycin. Spiking experiments revealed adequate recoveries within the dynamic ranges of the calibration curves of enrofloxacin (92% ± 6%), sulfamethazine (130% ± 21%), sulfadiazine (89% ± 20%) and streptomycin (93% ± 4%).

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.
