[Approach to elaborating immunochemical methods for removing peptides from the blood of kidney failure patients].
A homogenic peptide (m. w. 2100 dalton) was isolated from blood serum of patients suffering from renal failure by gel chromatography on a Sephadex G-25 column and by partition chromatography on a column with cellulose MN-300. The peptide was not detectable in the blood of healthy donors. The amino acid composition of the peptide was studied. To obtain an immunosorbent, the peptide was conjugated by the bifunctional reagent, glutaric aldehyde. An optimal conjugation variant promoting the formation of conjugates with a molecular weight of 60000 dalton was developed. The molecular weight of the conjugates was measured by gel chromatography on a Sephadex column G-50 and with the aid of disc electrophoresis in polyacrylamide gel.
