| Abstract | Large-scale experimentation is becoming instrumental in enabling new discoveries in systems biology and personalized medicine. We developed a multiplexed high-throughput nanoimmunoassay chip capable of quantifying four biomarkers in 384 5 nL samples, for a total of 1536 assays. Our platform, compared to conventional methods, reduces volume and reagent cost by ∼1000-fold. We applied our platform in the context of systems vaccinology, to assess the synergistic production of inflammatory cytokines from dendritic cells (DCs) stimulated with 10 different adjuvants that target members of the Toll-like receptor (TLR) family. We quantified these adjuvants both alone and in all pairwise combinations, for a total of 435 conditions, revealing numerous synergistic pairs. We evaluated two synergistic interactions, MPLA + Gardiquimod and MPLA + CpG-B, in a mouse model, where we measured the same inflammatory cytokines in bronchoalveolar lavage and in blood serum at 4 different time points using our chip, and observed similar synergistic effects in vivo, demonstrating the potential of our microfluidic platform to predict agonistic immunogenicity. More generally, a high-throughput, matrix-insensitive, low sample volume technology can play an important role in the discovery of novel therapeutics and research areas requiring large-scale biomarker quantitation. |

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.
