| Abstract | A new stationary phase based on wide-pore hybrid silica bonded with amide ligand has been used to explore the utility of HILIC for the analytical characterization of protein biopharmaceuticals. Various, highly-relevant samples were tested, including different insulins, interferon -2b and trastuzumab. This work shows that HILIC can be successfully employed for the analysis of therapeutic proteins and mAbs, using mobile phase compositions comprised of between 65 and 80% ACN and 0.1% TFA. In terms of elution order and selectivity, these HILIC separations have proven to be highly orthogonal to RPLC, while the kinetic performance remains comparable. In the case of characterizing trastuzumab, HILIC was uniquely able to resolve several important glycoforms at the middle-up level of analysis (fragments of 25-100kDa). Such a separation of glycoforms has been elusive by other separation mechanisms, such as RPLC and IEX. Besides showing orthogonality to RPLC and improved separations of glycoforms, HILIC offers several additional benefits for biopharmaceutical characterization: i) an inherent compatibility with MS, ii) a reduced requirement for very high mobile phase temperatures that are otherwise needed in RPLC to limit undesirably strong adsorption to the surface of the stationary phase, and iii) the possibility to couple several columns in series to improve resolving power, thanks to comparatively low mobile phase viscosity. |

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.
