  • ICC/IF image of ab107896 stained MCF-7 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 ab107896 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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) at a concentration of 1.43µM. This antibody also gave a positive result in 100% Methanol fixed (5 min) HeLa and HepG2 cells, and in 4% Formaldehyde fixed (10min) HepG2 cells at 1ug/ml.

Ich habe Rückmeldung aus dem Labor erhalten: Leider sieht es so aus, dass der ab128104 Anti-RYBP antibody [1B2] nur gegen das rekombinante Protein getestet wurde.

Soll ich Ihnen daher (wie besprochen) den ab107896 Anti-RYBP antibody zukommen lassen?
