Purified tumour-derived cytokeratins.
Our Abpromise guarantee covers the use of ab49778 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-Fr||1/100 - 1/200.
Acetone fixation recommended.
|IHC-P||1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
|ICC/IF||Use a concentration of 10 µg/ml.|
ICC/IF image of ab49778 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab49778, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG(H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM
