The Liposome Plasma Stability Test Kit (Catalog number SPS20) is designed for study stability of liposomal drugs in human or animal plasma or serum.  Ready-to-use spin columns are employed for separation of liposomal drugs from non-encapsulated drugs and drugs that binds plasma proteins.  After a quick spin-column process, more than 95 % of plasma proteins together with the  or free drugs stay on the column. The intact liposomal drugs are in the elute.  For example, the recovery yield of the intact liposomal doxorubicin was 96 % after incubation of the liposomal drug with human plasma at 37°C for 2 hours.

The Liposome Plasma Stability Test Kit (Catalog number SPS20) includes 20 pre-packed spin columns for analysis of 20 samples.
