Associated with PTH, assess renal osteodystrophy

Evaluate osteoblastic activity for patients under prolonged corticosteroid therapy

Benefits

ACCURATE AND RELIABLE ASSAY

Assay principle: sandwich

Two monoclonal antibodies specific to osteocalcin recognizing the intact 1-49 region and 1-43 peptide are used for the sandwich. The first one is adsorbed onto the tube walls. The second one, radiolabeled with iodine-125, is used as the tracer.

One-step assay procedure: 2h at RT / shaking.
