Standard Curve for Calcitonin dilution range 1pg/ml to 1ug/ml using Capture Antibody Mouse monoclonal [16B5 ] to Calcitonin (ab11493) at 5ug/ml and Detector Antibody Rabbit polyclonal to Calcitonin (ab8553) at 0.5ug/ml
Calibration curves of several procalcitonin sandwich ELISAs using a range of monclonal antibodies available agaisn't procalcitonin, calcitonin and catacalcin fragments. Capture antibodies used at 1 µg/well and detection antibodies at 0.1 µg/well. Dark blue square = ab11493 [16B5] (calcitonin fragment) and ab11494 [42] (procalcitonin fragment). Light grey circle = ab11497 [24B2] (calcitonin fragment) and ab11484 [13B9] (calcitonin fragment). Grey triangle = ab11487 [14C12] (catacalcin fragment) and ab11496 [14A2] (calcitonin fragment). Dark grey circle = ab14813 [27A3] (procalcitonin fragment) and ab11491 [22A11] (catacalcin fragment).
Amino acid sequence and schematic diagram of human procalcitonin and the N-terminal, calcitonin, and katacalcin (catacalcin) fragments.
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.
