5 Reasons Scientists Choose Mercodia Glucagon ELISAs




Sample volume requirements have significantly limited the use of glucagon assays. Most commercially available methods require at least 50-100uL of plasma. This has direct implications on the number of analytes that can be measured, the number of time points that can be examined and thus, the scope of scientists’ conclusions. Mercodia offers 2 very low sample volume assays and assay choice depends on sample type.

Human Samples: Mercodia Glucagon ELISA (10-1271-01)

                                              Animal Samples: Mercodia Glucagon ELISA - 10uL (10-1281-01)



A study published in early 2014 showed that key performance characteristics of commercially available glucagon assays were significantly lacking.

In a subsequent study, the new Mercodia assay (10-1271-01) was included and based on the authors’ extensive evaluation and expertise in this field, they determined that “the Mercodia assay has the best performance, in terms of specificity, precision and sensitivity data”. They concluded that only the Mercodia assay was “suitable for measuring glucagon concentrations in clinical samples”. Wewer Albrechtsen NJ et al. (2014) Diabetologia 57:1919-1926

Even though the physiological range of glucagon is reported to be 0 – 30 pmol/L (0 – 105 pg/mL), for many years, commercially available glucagon assays did not provide sufficient sensitivity for detecting glucagon under a variety of physiological conditions. Experts in the field state: “Clearly, assays with sensitivities >5pmol/L are, therefore, unsuitable for the complete characterization of glucagon secretion.” The sensitivities of Mercodia’s two assays, coupled with broad dynamic ranges, afford scientsts the ability to measure physiologically relevant concentrations of glucagon in a variety of experimental paradigms.

Mercodia Glucagon ELISA (10-1271-01): 1.5 – 130 pmol/L (5 – 453 pg/mL)
Mercodia Glucagon ELISA – 10uL (10-1281-01)2 – 180 pmol/L (7 – 627 pg/mL)



While glucagon’s actions may be unique, its sequence is not (see above). The use of an assay that cross-reacts with other glucagon-containing proteins may result in inaccurate characterization of alpha cell function and glucagon kinetics under various physiological conditions, as well as misinterpretation of how a subject is responding to therapy.

Mercodia’s glucagon assays are based on 2 highly specific monoclonal antibodies that recognize the terminal ends of glucagon.



Glucagon’s sequence is highly conserved across species, but validation of different sample types is crucial because sequence homology is not the only factor that affects antibody-antigen binding in an immunoassay (e.g., matrix interferences). Mercodia’s assays contain a unique blocking solution to prevent or minimize matrix interferences.
In addition, both of the Mercodia glucagon assays are based on the same 2 monoclonal antibodies, ensuring the same specificity for translational sample analyses. Mercodia’s glucagon assays can be used with cell culture, rodent, canine, porcine, nonhuman primate and human samples.
