Ring-like formations in drying DNA drops could affect hybridization studies

he design of arrays in which DNA droplets are sequentially deposited onto a glass surface for hybridization studies, the researchers report.

"Without optimization of the wetting conditions, it is possible to miss all the DNA in the ring stain of a dried droplet, resulting in false negatives," Wong said. "We need to think of strategies to minimize this effect."

The co-authors of the paper are postdoctoral research associate Ivan Smalyukh, graduate students Olena Zribi and John Butler, and professor Oleg D. Lavrentovich, director of the Liquid Crystal Institute at Kent State.
