Cat. Num. AAA494654

• Gene Names: CALCA; CT; KC; CGRP; CALC1; CGRP1; CGRP-I
• Reactivity: Human
• Synonyms: Calcitonin; Calcitonin ELISA; CALCA elisa kit

• Reactivity: Human
• Specificity: Each crossreactant is spiked into a sample containing Calcitonin. Calcitonin level is measured before and after the spike. None of the crossreactants interfere with this Calcitonin ELISA. The small changes in Calcitonin measured are well within the intraassay precision statistics.
• Sequence Length: 141

• Samples: Human serum
• Assay Type: Sandwich
• Sensitivity: The sensitivity, or minimum detection limit, of this assay is defined as the smallest single value, which can be distinguished from zero at the 95% confidence limit. The Calcitonin ELISA has a calculated sensitivity of 1.0 pg/mL.
• Intended Uses: The Calcitonin ELISA is intended for the quantitative determination of Calcitonin in human serum.
• Preparation and Storage: 2 - 8 degree C

Principle of the assay: The Calcitonin Immunoassay is a two-site ELISA [Enzyme-Linked ImmunoSorbent Assay] for the measurement of the biologically intact 32 amino acid chain of Calcitonin. It utilizes two different mouse monoclonal antibodies to human calcitonin specific for well-defined regions on the calcitonin molecule. One antibody binds only to Calcitonin 11-23 and this antibody is biotinylated. The other antibody binds only to Calcitonin 21-32 and this antibody is labeled with horseradish peroxidase [HRP] for detection. In this assay, calibrators, controls, or patient samples are simultaneously incubated with the enzyme labeled antibody and a biotin coupled antibody in a streptavidin-coated microplate well. Thus the calcitonin in the sample is "sandwiched" between these two antibodies. At the end of the assay incubation, the microwell is washed to remove unbound components and the enzyme bound to the solid phase is incubated with the substrate, tetramethylbenzidine (TMB). An acidic stopping solution is then added to stop the reaction and converts the color to yellow. The intensity of the yellow color is directly proportional to the concentration of calcitonin in the sample. A dose response curve of absorbance unit vs. concentration is generated using results obtained from the calibrators. Concentrations of calcitonin present in the controls and patient samples are determined directly from this curve.

NCBI Description

This gene encodes the peptide hormones calcitonin, calcitonin gene-related peptide and katacalcin by tissue-specific alternative RNA splicing of the gene transcripts and cleavage of inactive precursor proteins. Calcitonin is involved in calcium regulation and acts to regulate phosphorus metabolism. Calcitonin gene-related peptide functions as a vasodilator and as an antimicrobial peptide while katacalcin is a calcium-lowering peptide. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2014]

Uniprot Description

CALCA: Calcitonin causes a rapid but short-lived drop in the level of calcium and phosphate in blood by promoting the incorporation of those ions in the bones. Belongs to the calcitonin family. 3 isoforms of the human protein are produced by alternative splicing.
