Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IH IF
The INK4a-ARF locus encodes two unrelated proteins both of which function in tumor suppression. p14ARF arrests the cell cycle in a p53-dependent manner. p14ARF binds to mdm2 and promotes the rapid degradation of mdm2 protein required for mdm2 modification and concurrent p53 stabilization and accumulation. This interaction is mediated by the exon 1beta-encoded Nterminal domain of p14ARF and a C-terminal region of mdm2. Deletion of the ARF-INK4a locus simultaneously impairs both the INK4a-cyclin D/cdk4-RB and the ARF-mdm2-p53 pathways.
Catalog #A3330-04AX
Suitable for use in Immunofluorescence, Western Blot and
Immunohistochemistry. Other applications have not been tested.
Recommended DilutionsWestern Blot: 5-10ug/ml for 2hrs at RT.
Immunohistochemistry (formalin/paraffin): 5-10ug/ml for 30 min at RT. Note: Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min.
Optimal dilutions to be determined by the researcher.
Positive Control:
HeLa cells, cervical carcinoma or breast fibroadenoma.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Clone TypePolyclonal
FormSupplied as a liquid in 10mM PBS, pH 7.4. Also available with BSA and azide. See A3330-04A
PurityPurified by Protein A affinity chromatography.
ImmunogenA synthetic peptide from the C-terminus of human p14ARF. Cellular Localization: Nuclear.
SpecificityMay show some additional bands with MW much higher than 14kD, however, the p14ARF area is relatively clean which permits an easy identification of the p14ARF band. For optimun results, immunoprecipitate p14ARF with Western blot.
Species CrossreactivityHuman.
