Defining a Peak and looking for SNPs • Peak is defined by a drop of 4.6 in the LRS from maximum • This is about 1 log unit • Pay particular attention to SNPs in our peak or region of interest

Gene Chips DNA microarrays • Can use fluorescent cDNAs (mRNAs or RNAs) as probes. • Yield the pattern of gene expression across 2 different conditions. • Can examine many (thousands) of genes at once. • Does not give cell-by-cell resolution.

In situ hybridization • Finding out which cell(s) express a gene by probing for mRNA. • Probes to mRNA can be made of antisense DNA or RNA (sense is control). • Probes are labeled. • Probes hybridize with specific mRNAs being made in a cell. • Can only examine expression of one or two genes at a time.
