Our Abpromise guarantee covers the use of ab70744 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/2000 - 1/10000. Detects a band of approximately 120 kDa (predicted molecular weight: 94 kDa).
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionPotential cell cycle regulator that may play a role in carcinogenesis of cancer cells. Mitotic phosphoprotein regulated by the ubiquitin-proteasome pathway. Key regulator of adherens junction integrity and differentiation that may be involved in CDH1-mediated adhesion and signaling in epithelial cells.
Tissue specificityAbundantly expressed in fetal liver. Expressed at lower levels in bone marrow, testis, colon, and placenta.
Sequence similaritiesBelongs to the SAPAP family.
Developmental stageElevated levels of expression detected in the G2/M phase of synchronized cultures of HeLa cells.
modificationsUbiquitinated, leading to its degradation.
Phosphorylated upon DNA damage, probably by ATM or ATR. Decreased phosphorylation levels are associated with the differentiation of intestinal epithelial cells.
Cellular localizationNucleus. Cytoplasm. Cytoplasm > cytoskeleton > spindle. Localizes to the spindle in mitotic cells. Colocalizes with CDH1 at sites of cell-cell contact in intestinal epithelial cells.

ICC/IF image of ab70744 stained A549 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 (ab70744, 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.
IHC image of HURP staining in Human Testis formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ 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 ab70744, 1 µg/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.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
Detection of HURP by Western Blot of Immunprecipitate. ab70744 at 1µg/ml staining HURP in HeLa whole cell lysate immunoprecipitated using ab70744 at 3µg/mg lysate (1 mg/IP; 20% of IP loaded/lane).
Chemiluminescence with exposure time of 10 seconds.
