#58 — One of the most common goals in biology is to prove that two proteins colocalize. Usually, colocalization happens as part of a crucial disease pathway or poorly understood yet fundamental physiological process.In this episode, we discuss two methods to quantify colocalization: Pearson’s correlation coefficient and Mander’s colocalization coefficient. Listen and learn their use cases and limitations and how to choose appropriate regions of interest in each case.
