C-peptide-measurement: a simple method for the improvement of specificity

Journal of Immunoassay
U KrauseJ Beyer

Abstract

Sera containing insulin antibodies and proinsulin give artifactual high readings in C-Peptide measurement. This problem can be circumvented by the removal of antibodies and proinsulin prior to C-Peptide assay. A method is described which enables the removal of antibodies and proinsulin from sera without affecting the C-Peptide determination. Furthermore, this method allows a semiquantitative estimation of proinsulin, provided there is enough cross reactivity of the C-Peptide antibody with proinsulin.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
