Description

The Ultrasensitive Mercodia C-peptide ELISA is a high-quality immunoassay for specific quantification of low levels of human C-peptide in serum, plasma, cell culture media, or urine.

The Ultrasensitive Mercodia C-peptide ELISA is a highly specific tool registered for in vitro diagnostics (IVD) use. It is calibrated against the International Reference Reagent for human C-peptide, IRR84/510. The specificity of the utilized antibodies enables measurement of human C-peptide without interference from insulin or proinsulin, and measurement of human C-peptide in mouse and rat models.

Each Mercodia C-peptide ELISA kit contains reagents for 96 wells, sufficient for 42 samples and one calibrator curve in duplicate. The microplate strip format (12 strips x 8 wells) is ideal when only a limited number of samples need to be analyzed.

Higher sensitivity can be achieved by using an alternative protocol described in technical note TN34-0144.

Mercodia Diabetes Antigen Control (10-1134-01 (US only) or 10-1164-01) is designed to be used as a two-level control in the Ultrasensitive C-peptide ELISA.
