Haptoglobin Level

Abstract A method is described for the quantitation of serum hemoglobin-binding capacity (haptoglobin level) using cellulose acetate membrane electrophoresis. Electrophoresis is carried out for 90 mm. Eight membranes are dried, stained, and scanned within 45 mm. The reproducibility of this technic is within ± 10%.

Abstract Serum haptoglobin has been advocated as an indicator of intravascular hemolysis. We have evaluated a nephelometric determination of serum haptoglobin. The assay is sensitive and exhibits within-run precision in the range of 2.5-7.4% coefficient of variation (CV) and between-run precision of 7.0% (CV). In addition, when haptoglobin values determined with the nephelometric assay were compared with hemoglobin-binding capacity determined by electrophoresis, the correlation coefficient was 0.968. The assay is essentially independent of phenotype and free of significant interference by hemolysis. The clinical correlation of haptoglobin values obtained for 100 selected patients with the nephelometric technique correlated well, if less than 250 mg/L, with the presence of hemolytic disease.

The magnetic composite microspheres of cassava starch have been prepared by magnetization of one-step oxidation, using cassava starch as natural macromolecule material. The condition effect on magnetic content was evaluated by single factor experiments, such as the mass concentration of starch, reaction temperature, reaction time, stirring speed, initial pH and ferrous solution volume. Preparation conditions were optimized by these evaluation experiments. The prepared magnetic composite microspheres were characterized by infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), and other means.
