IMPORTANT INFORMATION ABOUT THIS STAGE<br />

To help ensure the best results, carefully read the information below<br />

before you begin this stage of the protocol.<br />

• This procedure requires two operators working simultaneously<br />

when loading samples onto arrays and placing arrays in the<br />

hybridization ovens.<br />

• If using a thermal cycler, it is critical that the samples remain at<br />

49 °C after denaturation and while being loaded onto arrays. If you<br />

have a GeneAmp PCR System 9700 located adjacent to the<br />

hybridization ovens, we recommend using method 1. Otherwise,
