QC100, Quantikine Immunoassay Control Set 869 for Glucagon - Please Inquire
The Quantikine Glucagon Immunoassay is a 4.5 hour solid-phase ELISA designed to measure Glucagon in cell culture supernates, serum, and plasma. It contains natural porcine Glucagon as the standard. The antibodies were raised against a human Glucagon synthetic peptide. This immunoassay has been shown to accurately quantitate human, mouse, rat, and porcine Glucagon.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
The recovery of Glucagon spiked to levels throughout the range of the assay in various matrices was evaluated.

To assess the linearity of the assay, samples spiked with high concentrations of Glucagon were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Glucagon is a pancreatic peptide hormone that plays a critical role in glucose metabolism and homeostasis. Mature Glucagon is generated from its precursor by the prohormone convertase PC2/PCSK2 in pancreatic alpha-cells. Glucagon is secreted in response to low blood glucose (hypoglycemia) and downregulated in response to high blood glucose (hyperglycemia). Glucagon production is under the control of both hormones and neurotransmitters. Glucagon inhibits Insulin secretion, and vice versa. Glucagon stimulates hepatic gluconeogenesis and glycogenolysis, thereby increasing blood glucose. Like insulin, Glucagon is dysregulated in type 2 diabetes (T2D) and contributes to its pathology.
Refer to the product for complete assay procedure.
The conjugate must be kept cold during use. Bring all other reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
Wash and aspirate the plate a total of 2 times with Wash Buffer prior to assay.
