| Abstract | Identification of New World monkey MHC-DRB alleles has previously relied upon labor-intensive cloning and sequencing techniques. Here we describe a rapid and unambiguous way to distinguish DRB alleles in New World monkeys using the polymerase chain reaction (PCR), denaturing gradient gel electrophoresis (DGGE), and direct sequencing. The highly variable second exon of New World monkey DRB alleles was amplified using generic DRB primers and alleles were separated by DGGE. DNA was then reamplified from plugs removed from the gel and alleles were determined using fluorescent-based sequencing. The validity of this typing procedure was confirmed by the identification of all DRB alleles previously characterized by cloning and sequencing techniques from an individual cotton-top tamarin. Importantly, our analysis revealed DRB alleles not previously identified in this reference animal. Following validation of our technique, the protocol was employed for the characterization of MHC-DRB alleles in four other species of New World monkey: the pygmy marmoset, white-faced saki monkey, long-haired spider monkey and owl monkey. Using this technique, we identified five alleles from the cotton-top tamarin, five alleles from the owl monkey, three alleles from the long-haired spider monkey, three alleles from the white-faced saki monkey and two alleles from the pygmy marmoset. On the basis of phylogenetic tree analyses, 13 new DRB alleles were assigned to eight different MHC-DRB lineages. Whereas traditional DRB typing via cloning and sequencing provides limited information, our new technique provides a simple and relatively rapid way of identifying New World monkey MHC-DRB alleles. |

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.
