DNA Microarray Core Facility

Services

Affymetrix GeneChip

RNA Expression:  The core facility has the complete Affymetrix GeneChip system and can process RNA samples for a variety of organisms.  This includes chips for all model organisms for which Affymetrix has a chip available including human, mouse, rat, drosophila, c. elegans, yeast and arabidopsis.

Genome-wide SNP Analysis:  In addition to expression analysis the Affymetrix system can be used to perform genome-wide SNP analysis.  These arrays can also be used to determine genomic copy number alterations.

Spotted Microarray and mirVana miRNA

Labeling and Hybridization:  The core facility will label the RNA samples and perform the hybridizations to the slides for investigators. 

Slides Available:  30k Human, 30k Mouse, 10k Human, 10k Mouse, 10k Rat and miRNA arrays

New! Genome-Wide spotted oligo microarrays for human and mouse experiments. The core facility can now offer you genome-wide expression profiling for your experiments involving human or mouse RNA samples at a reduced cost. The facility can compare the expression profile of ~ 30,000 genes between two samples in either mouse or human for a total cost of approximately $250.00. The slides used are from the company known as Phalanx Biotec.

Custom Array Printing:  The core facility employs the use of a OmniGrid 100 spotting robot and will print custom oligo and cDNA arrays for users.

Scanning:  The facility employs the use of an Axon 4000B Laser Scanner.

Image Analysis:  GenePix is the image analysis software utilized for spotted microarray images.

Agilent Bioanalyzer - RNA Integrity Analysis

In our facility we employ the use of an Agilent Bioanalyzer which will assess the purity, potential degradation and genomic DNA contamination of RNA.

Analysis

Statistical Analysis:  The Microarray Core Facility can assist with initial analysis to determine fold-changes in genes.  For in-depth statistical analysis the user is referred to statisticians and computer scientists at UNMC that routinely provide those services.

Pathway Analysis:  The Microarray Core Facility has purchased access to the analysis program known as Ingenuity Systems.  Users are encouraged to utilize this program to further analyze their microarray data.
