Optimizations of DNA isolation and copy number analysis identifies regions of genomic gain/loss in early breast cancer

(Submitter supplied) DNA copy number changes with or without accompanying copy neutral changes such as unparental disomy (UPD) is a feature of the cancer genome that is linked to cancer development. However, technical problems with archived formalin-fixed, paraffin-embedded (FFPE) tissue samples have limited their general use in genomic profiling studies done using high-density single nucleotide polymorphism (SNP) microarray. more...

[Mapping250K_Sty] Affymetrix Mapping 250K Sty2 SNP Array

(Submitter supplied) Affymetrix submissions are typically submitted to GEO using the GEOarchive method described at http://www.ncbi.nlm.nih.gov/projects/geo/info/geo_affy.html The GeneChip® Human Mapping 500K Array Set provides consistently high coverage across different populations. It is comprised of two arrays, each capable of genotyping on average 250,000 SNPs (approximately 262,000 for Nsp arrays and 238,000 for Sty arrays). more...
