[Erythrocyte-associated plasma proteins, a further aspect of erythrocyte function?]

The amount of plasma proteins associated to erythrocytes was determined or calculated by using three different techniques. Thus, there are 3.48 X 10(12) g of protein in a single erythrocyte or 94.12 g of protein respectively in the total of all erythrocytes in a healthy man with a body weight of 70 kg. The mass of plasma protein associated to erythrocytes will decrease in case of immunocomplex aggregates or otherwise denatured plasma proteins being fixed to the erythrocyte surface so that from a purely calculating point of view protein amounts on a scale of up to 46% of all plasma proteins may enter the free blood plasma under extreme conditions. In this, an immediately efficient possibility of compensation is seen by the authors in case of an acute consumption of blood proteins.
