[Some regularities of dimer II formation in BODIPY-FL-labeled lipids].

Some regularities of dimer II formation from BODIPY-FL-labeled lipid probes using mono-, bis-, and tris-BODIPY-FL derivatives of gangliosides G(M1) and G(D1a) and mono- and bis-BODIPY-FL derivatives of triglycerides have been defined. BODIPY-FL-labeled glycolipids were shown in phospholipid layers to reveal a greater disposition towards dimer II formation than BODIPY-FL-labeled glycerides. The formation of dimer 11 was also shown to depend on the label position in the probe molecule. Probes bearing a label in the polar head area are more prone to dimer II formation than probes labeled in the apolar part of the molecule.
