Over the past 10-12 years the evolution of market leading dye terminator methods and automated capillary electrophoresis instrumentation has largely standardized the procedure for DNA sequencing, quickly making it more accessible, less resource intensive, and easier to perform at many different throughput levels. A critical component of this genomic workflow is the sequencing cleanup procedure, where contaminating artifacts of the sequencing reaction are removed prior to capillary electrophoresis. There are currently a number of viable DNA sequencing cleanup methods available using either filtration, precipitation, or sequestering. Each method has its own costs and benefits and is a proven way of purifying reaction samples. In collaboration with a comprehensive DNA Analysis Core Facility that utilizes state-of-the-art sequencing chemistires and technology, a microplate washer fitted with an integrated vacuum filtration module was used to perform DNA sequencing reaction cleanup. Results were substantiated against a gel filtration method currently used by the collaborator. Evidence provided by this demonstration support the efficacy of the microplate washer demonstrated here to contribute to the genomic workflow typical of many molecular biology laboratories and core facilities.

Inhibition of The Auto-inflammation Suppressor Protein ISG15 Triggers Preeclampsia by Blocking Trophoblast Migration and InvasionPoster
In summary, ISG15 expression levels are crucial for trophoblast morphology and function (migration/invasion). By blocking trophoblast invasion, reduced ISG15 levels could contribute to impaired spiral artery transformation that reduces utero-placental blood flow in preeclampsia. Thus, agents inducing ISG15 expression are likely to be therapeutic in preeclampsia.
An Emerging Phenotype of Partial RAG 1/2 Deficiency Among Young Children with Autoimmunity and Viral InfectionsPoster
We describe the natural history of a cohort of 12 patients with confirmed partial RAG1/2 mutations and autoimmunity at a young age. We were seeking the link between viral infections and autoimmunity and tested candidate biomarkers that may reflect the underlying RAG1/2 protein deficiency.READ MORE
