Properties

Applications

Our Abpromise guarantee covers the use of ab54210 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Notes
Flow Cyt Flow Cyt: 1/50.
WB WB: 1/500 - 1/2000. Tested using a recombinant protein expressed in E. coli. We have no data on the detection of the endogenous protein and would welcome feedback from anyone that has performed a WB with ab54210 using cell lysates.
ELISA ELISA: 1/10000.
IHC-P IHC-P: 1/200 - 1/1000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. Recommended antigen retrieval: Place slides in a special glass slide holder and fill in the rack with slides to ensure even heating. Rinse rack in 1L of Citrate buffer in ordinary pressure cooker,(0.01M,pH6.0) to immerse all slides. Cover the cap and heat for 15-20 minutes on electric cooker until water boils. Begin timing, only 2 minutes in high-pressure Remove the pressure cooker, Allow it to cool(Cool the slides at room temperature) Rinse the slides in PBS for 5 minutes

Target

  • RelevanceThe CDKN2A locus gives rise to 2 distinct transcripts from different promoters. The transcripts have been designated p16(INK4A) and p14(ARF). This chromosomal region undergoes a number of inversions, translocations, heterozygous deletions, and homozygous deletions in a variety of malignant cell lines including those from glioma, non-small cell lung cancer, leukemia, and melanoma. Deletion of the region containing CDKN2A is found in more than half of all melanoma cell lines. In spite of the structural and some functional differences, all the proteins encoded by the CDKN2A gene are involved in cell cycle G1 control.
  • Cellular localizationCytoplasmic and Nuclear
  • Database links
  • FormThere are 4 isoforms produced by alternative splicing. Isoform 1 also known as: p16INK4a; Isoform 3 also known as: p12; Isoform 4 also known as: p14ARF; p19ARF; ARF.

    • Overlay histogram showing HeLa cells stained with ab54210 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab54210, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde/permeabilized in 0.1% PBS-Tween used under the same conditions.

    Thank you for your patience in awaiting our reply, the person who did the testing was away for several days. The testing was done at a 1/50 dilution. The datasheet is being updated to reflect this. Please let me know if you have any further questions.

    Thank you for contacting us. The concentration for this product is not determined as it is from ascites. Concentration values are only meaning for purified antibodies, since those from ascites may contain proteins other than the protein of interest. There...
