PurityImmunogen affinity purified
Purification notesab76942 was affinity purified using an epitope specific to PTPN12 immobilized on solid support. Antibody concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.
Our Abpromise guarantee covers the use of ab76942 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. Predicted molecular weight: 88 kDa.|
|IP||Use at 2-5 µg/mg of lysate.|
|ICC/IF||Use a concentration of 5 µg/ml.|
|IHC-P||1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|

Developed using the ECL technique.
Predicted band size: 88 kDa
Observed band size: 118 kDa why is the actual band size different from the predicted?
Additional bands at: 45 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 30 seconds
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human stomach carcinoma (left) and colon carcinoma (right) tissues labelling PTPN12 with ab76942 at 1/200 (1µg/ml). Detection: DAB.
Lane 1: ab76942, at 1 µg/mg, staining PTPN12 in HeLa whole cell lysate by Western blot of immunoprecipitate (1 mg of lysate for IP, 20% of IP loaded). Immunoprecipitation was performed by using ab76942 at 3µg/mg of lysate.
Lane 2: Control IgG.
Detection: Chemiluminescence with an exposure time of 3 seconds.
ICC/IF image of ab76942 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 (ab76942, 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.
