One advantage is that glass cDNA microarrays are relatively inexpensive, making them a suitable option for researchers. Another advantage is These microarrays offer adaptability in design, allowing them to be customized to meet the specific needs of various scientific experiments. A third advantage is they don’t require specialized equipment for hybridization, meaning that the process can be carried out with standard lab tools that are commonly available. Lastly, they provide higher sensitivity in detecting gene expression due to their longer target sequences, which can be up to 2 kilobases in length.
