Apogee A60 Micro-PLUS

The Research Group for Metabolic Diseases recently acquired an Apogee A60 Micro-PLUS flow cytometer and is currently validating its performance. The A60 Micro-PLUS has unprecedented sensitivity and resolution, making it ideal for detecting and characterising small biological particles such as microvesicles and exosomes. This is made possible by several technological advances including:

• 3 powerful, spatially separated lasers (405nm, 488nm, 638nm);

• 12 highly sensitive detectors distributed between the three lasers;

• 405nm laser for light scatter to improve detection of small particles;

• A novel light scatter detector module (medium-angle light scatter; MALS), which is sensitive to light scatter from small particles;

• Ability to analyse samples at low flow rates down to 0.75µL/min.


In addition, we use various immunological methods for quantification and characterization of proteins (ELISA, Western Blots, Immunopurification).

Proteins are also studied by various chromatographic methods as well as by use of a number of detergents (membrane proteins).

We intend to study cell cultures under various conditions mimicking in vivo pathophysiological processes.


Figure 1: Performance test of Apogee A60 Micro-PLUS demonstrated that it is capable of identifying 100nm silica beads with similar refractive properties to biological samples (A; gate 2) and clearly separate distinct size populations of silica beads ranging in size from 180nm to 880nm (B, gates 4-9). In addition, analysing a platelet-free plasma sample labelled with lactadherin-FITC and PE-conjugated anti-human CD36 antibody, microvesicles could also be detected (C) and their expression of CD36 accurately assessed (D).
