Each labeling reaction started with 1µg of double digested MCF7 and normal breast DNA, and followed the standard conditions per Agilent CGH array recommendations. Labeled reactions using the Agilent Genomic DNA Enzymatic Labeling kit with GE Amersham Cy dyes were purified with Microcon (Millipore). Labeled DNA from BioPrime® Total for Agilent® aCGH Labeling kit and BioPrime® Total was purified using the included Purelink™ purification columns. Array data were collected from Agilent aCGH 4x44K arrays using Agilent array scanner, Feature Extraction and CGH Analytical Software. BioPrime® Total for Agilent® aCGH Labeling kit produced excellent DLRSpread value and higher signal-to-noise ratios. This indicated that the Invitrogen’s new kit had higher efficiency in labeling the DNA samples and that probe-to-probe noise remained low.
Eliminate complicated volume-reduction steps
Comparing PureLink™ (Invitrogen) and Microcon (Agilent) indicates that the majority of the free nucleotides are removed with PureLink™ purification. In addition PureLink™ also produces more higher molecular weight reaction products. The labeling data (not shown) further indicated that there is no purification bias for labeled and unlabeled nucleotides, as the DOL was not effected by two purification methods.

Reaction products were separated by electrophoresis in 6% TBE-Urea gels and visualized on a Typhoon scanner/imager (Applied Biosystems) using the fluorescein channel (MW markers) and Cy/AF channels (labeling reaction products).
