Calibration Protocol - Plate Reader Abs600 (OD) Calibration with Microsphere Particles v2

Abstract

You will prepare a dilution series of monodisperse silica microspheres and measure the Abs600 in your plate reader. The size and optical characteristics of these microspheres are similar to cells, and there is a known amount of particles per volume. This measurement will allow you to construct a standard curve of particle concentration which can be used to convert 600 nm absorbance measurements into an estimated equivalent number of cells. </p
