Our Abpromise guarantee covers the use of ab40963 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 10 µg/ml.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 44 kDa).|
FunctionNAD-dependent protein deacetylase. Activates or deactivates mitochondrial target proteins by deacetylating key lysine residues. Known targets include ACSS1, IDH, GDH, SOD2, PDHA1, LCAD, SDHA and the ATP synthase subunit ATP5O. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels.
Tissue specificityWidely expressed.
Sequence similaritiesBelongs to the sirtuin family. Class I subfamily.
Contains 1 deacetylase sirtuin-type domain.
modificationsProcessed by mitochondrial processing peptidase (MPP) to give a 28 kDa product. Such processing is probably essential for its enzymatic activity.
Cellular localizationMitochondrion matrix.

Anti-SIRT3 antibody (ab40963) at 1 µg/ml + Human liver tissue lysate - total protein (ab29889) at 10 µg
IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution
Performed under reducing conditions.
Predicted band size: 44 kDa
Observed band size: 50 kDa why is the actual band size different from the predicted?
Additional bands at: 32 kDa, 36 kDa. We are unsure as to the identity of these extra bands.
The band observed at 32 kDa is thought to represent the 28 kDa processed form of SIRT3.
ICC/IF image of ab40963 stained MCF7 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 (ab40963, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit 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.
