Determining the absolute concentration is one of the strengths of the NTA technique. In scatter mode, the concentration of all particles is measured. Changing subsequently to the fluorescence mode, marked biologic nanoparticles are tracked. By using four lasers within a SOP assisted sequence, it is possible to differentiate between four different fluorescence dyes in the same sample.
Phenotyping of tetraspanins for instance, on vesicles and virus is facilitated, positive and isotype control as well.
To prepare instrument settings, standard EVs may be used.
