WT Sense Target Labeling Assay

index | previous question | next question

Why is there no pre-hybridization step for the arrays using the targets from the WT Assay?

The pre-hybridization step was required for the 3' target in the GeneChip® Expression Analysis Technical Manual.

No pre-hybridization step is necessary for the WT targets. There are many differences between the WT targets and the 3' targets in terms of the nature of the molecules (DNA vs. RNA), as well as labeling molecule and hybridization cocktail makeup. It has been found that pre-hybridization is not necessary for the WT targets.
