Popis: A method for separation of albumin–ribonuclease (RNase) conjugates has been proposed based on the use of macroporous silicates. It was established that about 76% of ligand-free human serum albumin (LFHSA) formed complexes with enzymes. It was shown that most of the conjugates of albumin and pancreatic RNase contained up to 2 mol enzyme per 1 mol LFHSA. The conjugates of albumin and bacterial RNase isolated from cells of the strain Bacillus intermedius 7P displayed higher specific activities, containing, on average, 2.3 mol RNase per 1 mol LFHSA (for the conjugates with molecular weights below 92 kDa) or 3.3 mol RNase per 1 mol protein carrier (for the conjugates with higher molecular weight).
