The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use at an assay dependent concentration. PubMed: 20631257|
|IHC-P||Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
|IP||Use at an assay dependent concentration.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 24 kDa (predicted molecular weight: 22 kDa).|
FunctionInvolved in redox regulation of the cell. Reduces peroxides with reducing equivalents provided through the thioredoxin system but not from glutaredoxin. May play an important role in eliminating peroxides generated during metabolism. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2). Reduces an intramolecular disulfide bond in GDPD5 that gates the ability to GDPD5 to drive postmitotic motor neuron differentiation.
Sequence similaritiesBelongs to the ahpC/TSA family.
Contains 1 thioredoxin domain.
modificationsPhosphorylated on Thr-90 during the M-phase, which leads to a more than 80% decrease in enzymatic activity.
Cellular localizationCytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

Lanes 1 - 4: Merged signal (red and green). Green - ab41906 observed at 23 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab41906 was shown to recognize Peroxiredoxin 1/PAG when Peroxiredoxin 1/PAG knockout samples were used, along with additional cross-reactive bands. Wild-type and Peroxiredoxin 1/PAG knockout samples were subjected to SDS-PAGE. ab41906 and ab8245 (loading control to GAPDH) at a concentration of 1 µg/ml and diluted to 1/10000 respectively were incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Predicted band size: 22 kDa
Observed band size: 24 kDa why is the actual band size different from the predicted?
IHC image of Peroxiredoxin 1/PAG staining in human liver carcinoma FFPE section, performed on a BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab41906, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
This protein is a homodimer consisting of two subunits with an expected molecular weight of 23kDa.
ICC/IF image of ab41906 stained HeLa cells. The cells were 4% formaldehyde 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 (ab41906, 5µg/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.
