FormuMax offers preformed fluorescent liposomes labeled with lipophilic dyes at affordable prices. The 100nm series has becoming increasingly popular. We are also adding other sizes such as the 200nm and 500nm fluorescent liposomes to satisfy the need for particle size standards in the field of flow cytometry. Our liposomes are produced by the extrusion technology which is known to produce the most uniform liposomes. However customers should be aware that liposomes prepared by the extrusion method still have rather broad particle size distribution. The particles size reported in the product sheet is for the mean diameter as measured by a standard DLS particle sizer.
