This is most prevalent in biomarker and drug development applications where a considerable change has been witnessed in how new diagnoses, prognoses, and therapeutic options are being discovered and developed using omic technologies. Moreover, many chronic diseases suggest a strong metabolic involvement or even a clear metabolic cause, including cancer. Together with the other omic disciplines, including genomics and proteomics, metabolomics plays a key role in the implementation of personalized medicine; evidence-based medicine designed for individually designed healthcare strategies. In turn, biomarker discovery and the understanding of biochemical pathways typically rely on a multimodal approach. Among these modalities, there continues to be a growing interest in CE-MS based development and implementation in clinical development.","PeriodicalId":15014,"journal":{"name":"Journal of Applied Bioanalysis","volume":"1 1","pages":"1303"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74861832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still, it is considered as non-conventional or alternative biological matrix, used to implement the information coming from other (so called conventional) bioanalytical samples, such as blood serum/plasma and urine, which only reflect exposure for a short period upon administration. Hair sampling is a non-invasive sampling procedure compared with bioanalytical methods for common biosamples.

We describe here an alternate, free of drug interference, immunocapture-LC/MS methodology for detecting anti-protein XYZ antibody in cynomolgus monkey plasma. In our approach, ADA-protein XYZ complexes are captured by a mouse monoclonal anti-drug antibody on streptavidin magnetic beads and separated from monkey plasma by a magnet. After elution, ADA are digested with trypsin and detected by LC/MS using a surrogate peptide common to monkey IgG subclasses 1-4. The immunocapture-LC/MS assay was applied to support a toxicology study and results were in close agreement with those from a modified ECL immunoassay. To our knowledge, this is the first application of using LC/MS for monkey ADA detection.","PeriodicalId":15014,"journal":{"name":"Journal of Applied Bioanalysis","volume":"7 24","pages":"117-128"},"PeriodicalIF":0.0,"publicationDate":"2016-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91436310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Can LC and LC-MS ever replace immunoassays?","authors":"T. Cross, M. Hornshaw","doi":"10.17145/JAB.16.015","DOIUrl":"https://doi.org/10.17145/JAB.16.015","url":null,"abstract":"This review is not intended as a summary of research and development of immunoassays and liquid chromatography-mass spectrometry but rather as a brief summary of the pros and cons of each technology applied to the quantitative measurement of biomolecules primarily in biofluids. The ability to detect and quantitate biomolecules revolutionised science in the twentieth century and continues to this day. It allows scientists, for example, to conduct research to find and validate biomarkers, but has found its most prominent role in diagnostic applications where it is used to monitor the presence and levels of biomolecules in human samples for the diagnosis and monitoring of disease, in food and beverages to ensure food safety and authenticity and in the environment to monitor the presence and levels of contaminants of ground, waste and drinking water. The growth in personalised or precision medicine will be accompanied by an increased need to detect and quantify panels of biomolecules as biomarkers, as well as a range of drugs taken as treatment or as a measure to delay or prevent onset of disease, following the paradigm of the right drug for the right patient at the right time and importantly at the right dose. Increased health and safety regulations demand more testing of food and beverage and environmental samples. With increasing need for biomolecule detection and quantitation comes the demand for high-throughput, lower cost per sample analysis and more accurate results. Traditionally, immunoassays have been the technology of choice for the detection and quantitation of biomolecules. However, over the past two decades alternative technologies have been shown to offer a complementary role to immunoassays. Liquid chromatography-mass spectrometry (LC-MS) is one such technology and for some applications has been shown to offer a powerful alternative to immunoassays. With the increasing demands for routine biomolecule quantitation coming from a broad range of fields, are immunoassays the best solution to keep pace with the increased throughput needed, demand for lower cost per sample and improved accuracy JOURNAL OF APPLIED BIOANALYSIS, October 2016, p. 108-116. http://dx.doi.org/10.17145/jab.16.015 (ISSN 2405-710X) Vol. 2, No. 4","PeriodicalId":15014,"journal":{"name":"Journal of Applied Bioanalysis","volume":"25 1","pages":"108-116"},"PeriodicalIF":0.0,"publicationDate":"2016-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79142943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since antibodies bind antigens with high specificity and tight affinity, antibodies are an important reagent in experimental biology, assay development, biomedical research and diagnostics. Monoclonal antibodies are therapeutic drugs and used for vaccine development. Antibody engineering, biophysical characterization, and structural data have provided a deeper understanding of how antibodies function, and how to make better drugs. Isothermal titration calorimetry (ITC) is a label-free binding assay, which measures affinity, stoichiometry, and binding thermodynamics for biomolecular interactions. When thermodynamic data are used together with structural and kinetic data from other assays, a complete structure-activity-thermodynamics profile can be constructed. This review article describes ITC, and discusses several applications on how data from ITC provides insights into how antibodies function, guide antibody engineering, and aid design of new therapeutic drugs.","PeriodicalId":15014,"journal":{"name":"Journal of Applied Bioanalysis","volume":"31 1","pages":"90-102"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90920918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
