The scientists used a high-resolution method to record the electrical activity in individual rods in the mouse retina, which they accessed with an ultra-tiny glass pipette -- the width of about one-seventieth the size of a human hair -- filled with saline solution capable of conducting electricity.

"When people collect the mucus from the animal, they'll pipette it off or scrape it off," said author Margaret Braunreuther.

"But what we found is that when we pipette the mucus layer from our cell culture, we see a very different behavior after that action. We think that the act of pipetting or scraping this very soft polymeric solution is resulting in more liquidlike behavior."

Microinjection is a method for introducing cells, genetic material, or other agents directly into embryos, cells, or tissues using a very fine pipette.

At the time, Vallabh recalls, “I had never held a pipette.”
