Abstract
An immunoassay for CK isoenzyme or CK isoform is provided based on capture of the CK isoenzyme or CK isoform by a specific antibody immobilized through a cleavable linker containing a disulfide bond onto a solid phase and release of the resulting antibody-CK isoenzyme or antibody-CK isoform complex by the addition of a reducing agent to cleave the disulfide bond and simultaneously activate the CK isoenzyme or CK isoform.
