Abstract

An aqueous alcohol buffer solution for substantially ambient, in vitro preservation of mammalian cells for a selected duration. The solution generally contains a water-miscible alcohol in an amount sufficient to fix the sample cells without coagulation, an anti-clumping agent, and a buffer agent to maintain the solution at a pH within a range of four to seven.
