GeneTitan® Multi-Channel (MC) Instrument for expression and genotyping can be used for hybridization, washing, and imaging in a single instrument. GeneTitan® Instruments together with Affymetrix® High-Throughput (HT) Array Plates provide the hands-free, automated solution for microarray processing. With a broad selection of array plate formats, we use this instrument from discoveries through genome-wide SNP genotyping, to comprehensive explorations of gene expression profiles relating to important biological phenotypes, such as disease or drug response. We frequently use this instrument for large scale custom SNP genotyping programs using Axiom myDesign genotyping array solutions.
