High-performance liquid affinity chromatography: rapid immunoanalysis of transferrin in serum

Ohlson, Sten ; Gudmundsson, Britt-Marie ; Wikström, Per and Larsson, Per-Olof LU (1988) In Clinical Chemistry 34(10). p.2039-2043
Abstract
We describe a new method for quantitatively measuring substances of
clinical interest by high-performance liquid affinity chromatography
(HPLAC). As a model system we selected analysis for transferrin in human
serum with immobilized antibodies in a high-performance liquid
chromatographic system. SelectiSpher-10 Activated Tresyl columns (5 or
10 x 0.5 cm) were used for in situ coupling of polyclonal antibodies to
transferrin. The amount of transferrin eluted was determined by
integrating the eluted peak at 280 nm. The whole analytical
procedure--including injection of sample, washing, elution, and analysis
of data--takes only 7 min. We characterized the HPLAC system for
analysis of... (More)

procedure--including injection of sample, washing, elution, and analysis
of data--takes only 7 min. We characterized the HPLAC system for
analysis of transferrin in several ways: intra-assay CV approximately
3%; inter-assay CV 2-9%; linear response up to 1 mg/mL column volume;
detection limit approximately 3 micrograms; analytical recovery 98% +/-
2%; purity of eluted sample greater than 95% (SDS-PAGE). The HPLAC
method was compared with "rocket" immunoelectrophoresis, a commonly used
method of analysis for transferrin, and there was excellent correlation
between the two methods (r = 0.96, n = 60). Benefits of this HPLAC
technique include high precision, rapid analysis, and simplified sample
handling. (Less)
