摘要
An improved anticoagulant is based on a higher level of citric acid than is usual (at least about 0.2% weight by volume). The higher citrate is combined with an amino acid as a counterion. The amino acid prevents cellular damage often caused by elevated citrate levels. The amino acid citrate mixture also serves to preserve platelet concentrates and platelet rich plasma during room incubation. Not only does the amino acid citrate combination enhance platelet integrity, it completely inhibits the growth of bacteria such as Staphylococcus epidermidis. Collecting blood of plasma into such higher levels of citrate prevents activation of blood proteins so that fractions made from the blood or plasma have superior characteristics.
