アプリケーション
Our Abpromise guarantee covers the use of ab80 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| アプリケーション | Abreviews | 特記事項 |
|---|---|---|
| ICC/IF | 1/250. | |
| ICC | Use a concentration of 1 µg/ml. Fix with a 1:1 mixture of methanol:acetone at -20C for 10 mins (see image by Dr. David Bertwistle). | |
| ELISA | Use at an assay dependent concentration. | |
| IHC-P | Use a concentration of 1 µg/ml. PubMed: 11726500 | |
| WB | 1/1000. Detects a band of approximately 19 kDa (predicted molecular weight: 17 kDa).Can be blocked with Mouse CDKN2A/p19ARF peptide (ab2659). Multiple bands with this antibody have frequently been reported. We believe that this is due to the different modification states of p19ARF. Nuclear extraction may be necessary in some samples. | |
| IHC-Fr | 1/100. |

関連性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.
