As seen in Figure 3, the calibration curve starts to plateau for absorbance values above 1.4. Figure 5: OD600 of yeast cells as a function of the dry cell mass. This is always observed for samples containing particles (yeast cells), as the OD600 measurement is basically a turbidimetric measurement. By using a polynomial WebA calibration curve can be constructed by comparing measured OD 600 to expected OD 600 over a range of different concentrations. Expected OD 600 is determined by counting cell number using an alternative technique (for example microscope slide method) and converting to OD 600 using the rule of thumb that 1 OD 600 = 5 x 108 cells/ml for E. coli. calgary to edmonton freight
