I just need relative units (for example, if mutant have double amount of DNA than wt). A. Fluorescence intensity can be quantified by using standard units known as Molecules of Equivalent Soluble Fluorochrome (MESF). What is the difference between the different types of Users that are available with a Security and Logging license? In most cases, the measurement of "relative fluorescence intensity" is adequate, where the fluorescent channel number that best approximates the average fluorescence of one population is compared with the same value from a second population labeled with the same reagent.

These statistical tables can be formatted rather easily,by right clicking on the table and choosing the statistics of interest, or, by formatting the table. identify an inducible morphotype that facilitates organ entry by the pathogenic fungus Cryptococcus neoformans. I'm just measuring the total amount of DNA in one wt cyanobacteria spp, and comparing with the total amount of DNA with a modified strain that is supposed to have more DNA (so I should detect more DNA per cell). In FlowJo v10, we need to start with data from your calibration standards. The strict measurement being determined here is the molecules of equivalent fluorescence (MESF). You can apply this statistic to a particular fluorescence (I understand that this means: mean of fluorescence/cell). doi: 10.1002/cnr2.1155. However, it does not have a universal meaning, and it is incumbent upon the researcher or scientist to define it.
