MicroarrayHybridizationProtocol
Introduction:One microarray set consists of 7 nylon membranes with 2.5 x 7.5 cm dimension. 2304 genes were spotted onto nylon membranes (Schleicher and Schuell GmbH, Dassel, Germany) using a GMS417 Microarrayer (Genetic Microsystems, Woburn, MA) at 665 ?m distance between spots.Preparation of the cDNA probe (one microarray membrane set)In tube A prepare: 100mg Total RNADEPC water to 100 ?lIncubate the tube at 70......阅读全文
