Anti-HOXB13 antibody [mAbcam53931] (ab53931) at 5 µg/ml + HOXB13 Recombinant protein at 0.1 µg

Secondary
Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

Performed under reducing conditions.

Predicted band size: 31 kDa
Observed band size: 57 kDa why is the actual band size different from the predicted?



ab53931 recognizes the tagged HOXB13 recombinant protein which has an expected molecular weight of 57 kDa.

ICC/IF image of ab53931 stained Hela cells. The cells were 4% PFA fixed (10 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 (ab53931, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 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). This antibody also gave a positive IF result in HepG2 cells fixed in 4%PFA at 1ug/ml..

Overlay histogram showing HeLa cells stained with ab53931 (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 (ab53931, 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 IgG (1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.
