Abstract
An adaptation of the low-temperature low-salt ethanol procedure for the fractionation of rabbit plasma proteins into six fractions is described. The composition of the fractions and the distribution of haptoglobins, caeruloplasmin and transferrin were determined. The protein and protein-bound carbohydrate distribution in the fractions is similar to that of human plasma proteins separated by a similar procedure. The purification of albumin, [alpha] 1-acid glycoprotein, trapsferrin and [gamma] -globulin was carried out.
