Abstract

he effect of eight formulations on the integrity of freeze-dried human red blood cells (RBC) was studied. The formu­lations were made of human serum albumin (HSA), PVP 30k or dextran 40k, combined with glucose and sucrose. The combination HSA 10 % and sucrose 10 % assured the highest post-freezing protection of RBC. No forrnulation guaranteed che cells protection after freeze-drying. lt is suggested to explore the effects of high water linkers in a higher concentration and operational parameters to obtain a lower sublimation rate.
