Figure 3From: The development of a comparison approach for Illumina bead chips unravels unexpected challenges applying newest generation microarraysComparison of probe level content on subsequent array versions. For (A) the AB-huGSM and (B) the I-huBC two subsequent array versions were compared regarding their probe level content. (C) Generally, probe sequence changes on consecutive array versions can lead to different numbers and types of RefSeq hits in both array versions. We categorized RefSeq hits resulting from probe sequence changes into 4 hit categories. I-huBC-V1 and I-huBC-V2 were investigated regarding these hit categories based on the following RefSeq releases: (D) R4, (E R17, and (F) R24. (G) Concordances and differences in probe level content between I-huBC-V1 and I-huBC-V2 over all RefSeq releases.Back to article page
