  • Relevance
    The gene for CDK2NA generates several transcripts/proteins which differ from each other in their first exons. Three of these transcripts are generated by alternative splicing (isoform 1 a.k.a p16INK4A, isoform 2 and isoform 3 a.k.a p12), two of which are known to function as inhibitors of CDK4 kinase. One other transcript that is generated from this gene contains an alternate reading frame (ARF), with the first exon located 20kb upstream of the remainder of the gene(isoform 4 a.k.a. p14ARF, p19ARF, ARF). In spite of the structural and some functional differences, all the proteins encoded by the CDKN2A gene are involved in cell cycle G1 control.

  • Confocal image showing nuclear staining increased after HeLa cells transfected with CDKN2A/p14ARF.

    ICC/IF image of ab3642 stained HeLa cells. The cells were 4% paraformaldehyde fixed and then incubated in 0.1% trixtonX-100 to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with primary antibody ab3642 at a dilution of 1/250. An AlexaFluor®594 goat anti-mouse secondary IgG (ab150077) was used at a 1/1000 dilution. Anti-tubulin (ab7291) and an AlexaFluor®594 goat anti-mouse IgG (ab150120) were used as counterstains, both at a dilution of 1/1000. DAPI was used to stain the cell nuclei blue.

  • ICC/IF image of ab3642 stained HeLa 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 ab3642 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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.

I'm afraid we are not aware of other suitable negative controls other than brain. The current literature may be able to help hopefully. Sorry I couldn't help you more on this occasion,

Thank you for your enquiry. I would suggest as negative control tissue to use brain. I hope this will be of help.

Thank you for your enquiry. The peptide sequence of the immunogen remains proprietary. However, I can tell you that the peptide used corresponded to the C-terminal region of Human p14ARF. I hope this information helps, please do not hesitate to c...
