storage stability :
Store at 2-8 degree C. Do not freeze. The user must validate any other storage conditions. When properly stored, the reagent is stable to the date indicated on the label. Do not use the reagent beyond the expiration date. There are no definitive signs to indicate instability of this product; therefore, positive and negative controls should be tested simultaneously with unknown specimens. If unexpected results are observed which cannot be explained by variations in laboratory procedures and a problem with the reagent is suspected, contact Technical Support.

app notes :
Immunohistochemistry Procedure . Specimen Preparation: Formalin-fixed, paraffin-embedded tissues are suitable for use with this primary antibody. Deparaffinization: Deparaffinize slides using xylene or xylene alternative and graded alcohols. Antibody Dilution: If using the concentrate format of this product, dilute the antibody 1:25. The dilutions are estimates; actual results may differ because of variability in methods and protocols. Antigen Retrieval: Boil tissue section in 10mM Citrate buffer, pH 6.0 for 10 min followed by cooling at RT for 20 min. Primary Antibody Incubation: Incubate for 30 minutes at RT. Slide Washing: Slides must be washed in between steps. Rinse slides with PBS/0.05% Tween. Visualization: Detect the antibody as instructed by the instructions provided with the visualization system. Immunohistochemistry Dilution: 1:25. IHC Positive Control: Lymphoma
other info2 :
Immunogen: Synthetic peptide derived from C-terminus of human p14ARF. Control Tissue: Lymphoma. Cellular Localization: Nucleus. Entrez Gene Code: 1029. Pathway: Cell Cycle
products description :
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 N-terminal 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.

ncbi summary :
This gene generates several transcript variants which differ in their first exons. At least three alternatively spliced variants encoding distinct proteins have been reported, two of which encode structurally related isoforms known to function as inhibitors of CDK4 kinase. The remaining transcript includes an alternate first exon located 20 Kb upstream of the remainder of the gene; this transcript contains an alternate open reading frame (ARF) that specifies a protein which is structurally unrelated to the products of the other variants. This ARF product functions as a stabilizer of the tumor suppressor protein p53 as it can interact with, and sequester, the E3 ubiquitin-protein ligase MDM2, a protein responsible for the degradation of p53. In spite of the structural and functional differences, the CDK inhibitor isoforms and the ARF product encoded by this gene, through the regulatory roles of CDK4 and p53 in cell cycle G1 progression, share a common functionality in cell cycle G1 control. This gene is frequently mutated or deleted in a wide variety of tumors, and is known to be an important tumor suppressor gene. [provided by RefSeq, Sep 2012]
