Note Once the sample measurement is initiated it is not possible to do changes to the standard curve Protein concentration is determined using the standard curve by correlating absorbance values of samples with known concentration to calculate the concentration of the unknown sample In order to maintain accuracy and precision please ensure that the R value of the standard curve is 0 95 or greater KINETICS Please contact the Implen support for further details 48 NanoPhotometer NP80 N60 N50 C40 User Guide Version 1 0 5 QD OD600 METHOD OVERVIEW The growth of bacteria in liquid culture media is commonly monitored by measuring the optical density at 600 nm OD600 in small samples taken from the cultures OD600 measurements are typically used to determine the stage of growth of the bacterial culture thereby ensuring that cells are harvested at an optimum point that corresponds to an appropriate density of live cells Growth of bacterial cells typically progresses through a series of consecutive phases including lag log stationary and decline see Figure 1 In general cells should be harvested towards the end of the log phase using the optical density of the samples to determine when this point has been reached Since optical density in the case of OD600 measurements results from light scattering rather than light absorption this value varies depending on the type of bacterial cells in the culture in terms of size and sha
