BioArray™ Deoxyoligo B2 is a synthetic biotin-labeled sequence that can be used in eukaryotic expression assays and in aiding software programs such as the Affymetrix Microarray Suite by aligning the grid with the array image.

The Control Deoxyoligo B2, together with the Eukaryotic Hybridization Controls (included in Prod. No. ENZ-42661-30 or ENZ-42661-150), provides an internal control for assaying quality and performance. This is done by adding the controls to biotin-labeled target cRNA before hybridization to probe sequences on the array. Deoxyoligo B2 is supplied as a 3 nm solution.
