Cancer Functional Genomics Core

Core Leader: Muralidharan Jayaraman, Ph.D.
Location: Stanton L. Young Biomedical Research Center (BRC) – Rm. 1401

Description

Variable gene expression, across the genome, significantly impacts both the progression and prognosis of cancer. The Cancer Functional Genomics Core at the Stephenson Cancer Center offers cutting-edge technology to provide extremely accurate and reliable expression data in support of cancer-focused research. The versatile Agilent SureScan Microarray Scanner allows for scanning of genome-wide microarray profiles. Two instruments are available for quality assessment of purified RNA and DNA: the Biorad Experion™ Automated Electrophoresis Station and the Agilent 2100 Bioanalyzer. The Biorad CFX96™ Touch Real-Time PCR Detection System provides highly-reliable quantitative individual gene transcription profiling. Functional analysis of proteins in biochemical assays can be evaluated with the Perkin Elmer EnVision® Multilabel Reader. An ultimate high-throughput high-content imaging instrument, Operetta from Perkin Elmer, provides high resolution images for screening drugs with either live or fixed cells. Live cell metabolic changes, specifically oxygen consumption and pH change due to respiration, can be determined using the Agilent Seahorse XFE 96 Extracellular Flux Analyzer. The Incucyte Live cell Imaging System from Sartorius allows for many live cell physiological changes to be measured including cell proliferation, wound healing, and chemotaxis; for groups of cells overall changes can be assayed by spheroid formation and angiogenesis.
