TABLE 1.

Characteristics of AVB1 and ABV2 with or without AmB^a

Formulation	Concn (g/liter) of:			Size (nm)	AmB (% in water)	Size in PBS (nm)	AmB (% in PBS)
	PSP	DPPG	AmB
ABV1	10	2	0	91	0	97	0
ABV2	10	5	0	97	0	111	0
ABV1/AmB	10	2	2	96	97	118	92
ABV2/AmB	10	5	2	107	95	121	90

^aThe percentage of incorporated AmB was determined after sample filtration on 0.2-μm-pore-size filters. Under these conditions, nonformulated AmB did not pass through the filters (less than 1%).
