In the molecular biology of bacteria, OD600 is often used to estimate the current growth phase of a bacteria or other cells in suspension. The measured OD600 gives an estimate of the concentration of the cells in the liquid, which can be used to estimate the growth phase of the population. 600nm is in the visible wavelength an is approximately orangey-red. | In the molecular biology of bacteria, OD600 is often used to estimate the current growth phase of a bacteria or other cells in suspension.
