Control Oligo B2 (3 nM) is a pre-labeled DNA spike-in control required for hybridization to the control probes on the array utilized for grid alignment by AGCC. A failure to include Control Oligo B2 in the hybridization cocktail will result in the inability of the software to apply a grid over the scanned image, leading to the unrecoverable loss of sample data from the array. The absence of the Control Oligo B2 also voids the customer's ability to submit an array replacement request.
