Application Abreviews Notes
Sandwich ELISA Use a concentration of 5 µg/ml. Can be paired for Sandwich ELISA with Mouse monoclonal [42] to Procalcitonin (HRP) (ab24454) and Rabbit polyclonal to Calcitonin (ab8553). For sandwich ELISA, use this antibody as Capture at 5µg/ml with ab8553 as Detection.
Flow Cyt Use 1µg for 106 cells.
ELISA Use at an assay dependent dilution.
WB Use at an assay dependent dilution. Predicted molecular weight: 15 kDa.


  • RelevanceCalcitonin is a 32 amino acid peptide hormone synthesized by the parafollicular cells of the thyroid. It causes a rapid, but short lived, reduction in serum calcium and phosphate by promoting the incorporation of those ions in the bones. This effect is opposite to that of parathyroid hormone. Staining for calcitonin may be used for the identification of a spectrum of C cell proliferative abnormalities ranging from C cell hyperplasia to invasive tumors. Staining for calcitonin in medullary carcinoma of the thyroid produces a fine granular pattern in the cytoplasm. Amyloid deposits within the tumor may also exhibit varying degrees of calcitonin activity.

  • Overlay histogram showing SH-SY5Y cells stained with ab11493 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab11493, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
