| Abstract | We have developed a new high-throughput, high-resolution genotyping method for the detection of alleles at the human leukocyte antigen (HLA)-A, -B, -C, and -DRB1 loci by combining polymerase chain reaction (PCR) and sequence-specific oligonucleotide probes (SSOPs) protocols with the Luminex 100 xMAP flow cytometry dual-laser system to quantitate fluorescently labeled oligonucleotides attached to color-coded microbeads. In order to detect the HLA alleles with a frequency of more than 0.1% in the Japanese population, we created 48 oligonucleotide probes for the HLA-A locus, 61 for HLA-B, 34 for HLA-C, and 51 for HLA-DRB1. The accuracy of the PCR–SSOP–Luminex method was determined by comparing it to the nucleotide sequencing method after subcloning into the plasmid vector using 150 multinational control samples obtained from the International HLA DNA Exchange University of California Los Angeles. In addition, we performed the PCR–SSOP–Luminex method for HLA allele typing on DNA samples collected from 1,018 Japanese volunteers. Overall, the genotyping method exhibited an accuracy of 85.91% for HLA-A, 85.03% for HLA-B, 97.32% for HLA-C, and 90.67% for HLA-DRB1 using 150 control samples, and 100% for HLA-A and -C, 99.90% for HLA-B, and 99.95% for HLA-DRB1 in 1,018 Japanese samples. The PCR–SSOP–Luminex method provides a simple, accurate, and rapid approach toward multiplex genotyping of HLA alleles to the four-digit or higher level of resolution in the Japanese population. It takes only approximately 5 h from DNA extraction to the definition of HLA four-digit alleles at the HLA-A, HLA-B, HLA-C, and HLA-DRB1 loci for 96 samples when handled by a single typist. |

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.
