Knepp YR 1990 UL http://journal.pda.org/content/44/3/130.abstract AB The stability and delivery of IL-1β has been characterized in a polypropylene based syringe pump infusion system and in polyvinyl chloride based infusion bags, at concentrations ranging from 100 μg/ mL to I μg/mL. At higher concentrations (1μg/mL). minimal drug loss was observed in both systems. At low doses (100 μg/mL) in the syringe-pump system, the addition of 1% human serum albumin was necessary to prevent significant drug adsorption to the polypropylene drug reservoir.
