The Microarray Core is well equipped for detailed studies on gene expression as well as related services including RNA isolation and quality control; hybridizations to Affymetrix GeneChip and in house spotted cDNA arrays. Major instrumentation at our core facility include the following:
|
Agilent BioAnalyzer
A small amount of sample is loaded into the wells in a chip which is then loaded into the Bioanalyzer. Electrodes applied to the chip cause the RNA to move through microchannels filled with a sieving polymer and fluorescent dye. Fluorescence signal is plotted against run-time to generate an electropherogram or translated to gel-like images. Quality metrics such as 28S/18S ratio and RIN (RNA integrity number) are generated also.

Nanodrop ND-1000
The Nanodrop ND-1000 is a "cuvette-less" spectrophotometer. One microliter of sample is
placed on the pedestal and the Nanodrop stretches the liquid into a column of fixed length.
Fiberoptics is employed to pass filtered light through the stretched column. Absorbance at various
wavelengths is measured and reported through an attached computer.

Affymetrix GeneChip Scanner 3000 7G
An excitation laser is passed over the surface of the microarray at a very high resolution.
Emmissions are scanned at multiple wavelengths from a single excitation wavelength.
Autoloader allows temperature controlled handling of up to 48 GeneChips per run.
