WebInfinium Methylation Assay Overview. The Infinium Methylation Assay provides quantitative array-based methylation measurement at the single-CpG-site level, offering high resolution for understanding epigenetic changes. Genome-wide methylation analysis capabilities make this assay highly suitable for studying the biological role of DNA ... Web13 dec. 2024 · The 450K array consisted of 28% Infinium type I probes, whereas the EPIC array consists of 16% type I probes. We observed that CpG sites assayed using Infinium type I probes had significantly lower variance compared to sites measured with type II probes ( Figure 2b ; p < 2.2 × 10 −16 , Fligner–Kileen test).
WebAs previously shown for the 450k array [Citation 12], the 850k array generates biases, as it also relies on two different probe types (Infinium I and II). The 850k-specific probes are primarily Infinium II probes, which are less accurate, less reproducible, and considerably less sensitive for detection of extreme methylation values than Infinium I probes.
