\u00a0\u201cWe like the Andrew+ Pipetting Robot for automating routine sample prep and also for it being flexible enough for sharing across the lab and to applying to dynamic situations where you need to build new methods quickly for something that you might need to do.\u201d<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When Dr. Harry Whitwell, Lecturer, Imperial College London, was recruited to lead the integration of Proteomics at the National Phenome Centre (NPC), he knew that he would have to address a key bottleneck that he would be faced with: sample preparation.\u00a0 Funded by the Medical Research Council (MRC) and the National Institute for Health Research (NIHR), NPC is a world-class research institute that is focused on advancing metabolic phenotyping research to drive progress in Translational Medicine.\u00a0 When Dr. Whitwell announced that he had recruited a brilliant fellow by the name of Andrew to address NPC\u2019s sample preparation challenges, fellow scientists at Imperial College were keen to meet their new colleague.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

They were quite surprised to learn that their new colleague was not exactly a colleague, in the traditional sense.\u00a0 Andrew+<\/a>\u2122 is a pipetting robot that can prepare samples for many routine laboratory assays, leveraging electronic pipettes along with many connected devices such as fully automated Solid Phase Extraction (SPE) device<\/a>s, heater-shakers<\/a>, and magnetic bead separation devices.\u00a0 Unlike graduate students and research associates, the Andrew+ Pipetting Robot never tires, bores, or dispenses the incorrect volume of a reagent from the electronic pipettes that it handles.\u00a0 While most laboratory robotic platforms require an in-depth knowledge of a programming language such as Python<\/em>, there is no such barrier to building and execute laboratory protocols using the graphical drag-and-drop functionality within the OneLab<\/a>\u2122 Software that controls Andrew+.\u00a0 However, writing an entire protocol is usually not necessary, as the OneLab Protocol Library<\/a> contains many \u2018click-and-execute\u2019 protocols that can be used with little or no modification and that integrate seamlessly with Waters HPLC, UPLC\u2122, and LC-MS instruments.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\u201cAlongside wanting throughput and sample reproducibility, we also wanted to be flexible in experiments that we can support. The Andrew+ fits into our pipeline in a few different ways,\u201d commented Dr. Whitwell. Flexibility was a very important parameter for Dr. Whitwell when he was evaluating robotic platforms as the focus at NPC prior to his arrival was on profiling small molecules and lipids from biofluids, tissue extracts, and cell culture. \u201cRather than thinking of small molecules, lipids, and proteins as distinct modalities, we can combine them from experimental design all the way to data analysis. That is one of our ambitions,\u201d added Dr. Whitwell.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

A collaboration with Dr. Johanna Jackson, Department of Brain Sciences, Imperial College London utilized the Andrews+ for automating and streamlining sample prep for proteomics of Alzheimer\u2019s Diseased-brain. While working at Eli Lilly, Dr. Jackson studied synaptic changes and other disease processes in pre-clinical models of Alzheimer’s Disease. Upon returning back to Imperial College, Dr. Jackson led the UK DRI Multi-\u2018omics Atlas Project; an open resource mapping the cellular pathology of Alzheimer’s Disease, integrating data from Genomics, Transcriptomics, Proteomics and Immunohistochemistry.<\/p>

Alzheimer’s Disease, the main cause of dementia, impacts approximately 7 million people in the United States [1] and is rapidly becoming one of the most costly, lethal, and burdening diseases of the current century [2].\u00a0 From a pathological perspective, Alzheimer’s Disease is characterized by the deposition of A\u03b2 plaques and neurofibrillary tangles that are located predominantly in the neocortex and hippocampus.\u00a0 It is hypothesized that the accumulation of A\u03b2 plaques triggers a cascade of harmful events, eventually leading to neuronal dysfunction.\u00a0\u00a0\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In recent years, there has been an increasing focus on the role that the glial cells, namely astrocytes, microglia, NG2 glia and oligodendrocytes, play in the pathogenesis of Alzheimer’s Disease. Dr. Jackson\u2019s research applies a multi-omics approach to elucidate molecular signatures in the brain associated with accelerated cognitive decline in Alzheimer’s Disease. The ongoing study has involved the processing of >300 samples from post-mortem brains (middle temporal gyrus (MTG), somatosensory cortex (SOM)). The use of the Andrews+ reduced batch effects during sample preparation and supported non-specialist proteomics scientists to contribute to sample preparation, from protein extraction up to MS-ready sample.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The Imperial team leveraged the flexibility of Andrew+ in accommodating different assays with its interchangeable deck layout and ability to move labware around to suit the experiment at hand.\u00a0 Dr. Whitwell further added said Dr. Whitwell.\u00a0 \u201cAndrew+ played a pivotal role in driving this research forward,\u201d added Dr. Whitwell.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

One key finding was that protein markers associated with alterations of the astrocytes were found to be most strongly associated with accelerated cognitive decline.\u00a0 This insight may someday lead to the development of new drug targets that could substantially slow the progression of Alzheimer’s Disease in the future.\u00a0 The importance that state-of-the-art, robotic sample preparation plays in such studies is often overlooked.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
