参阅全部 CDKN2A/p19ARF 一抗
特异性On Western blot the antibody reveals IVT murine p19ARF and a band of the same size in CTLL2 cells. It detects a specific band in WT mouse embryo fibroblasts which is not present in p19ARF-null MEFs.

纯度Immunogen affinity purified
纯化说明The serum has been purified on a peptide-NHS-activated Sepharose column. Specific antibodies have been eluted with 100 mM glycine pH 2.5. The purified antibodies have been dialysed against PBS pH 7.4.
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.
|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). 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.|
相关性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.

Western blot of primary Mouse Embryo Fibroplasts (MEFs) using ab80 at 1 µg/ml. (30 µg of protein from total cell extracts per lane.)
ab80 antibody was tested on NIH 3T3 cells (which have a deletion of the p19ARF gene) as a negative control (-) and NIH 3T3 cells engineered to express HA-tagged p19ARF as a positive control (+).
Cells grown on coverslips were fixed with a 1:1 mixture of methanol:acetone at -20C for 10 mins. After drying, rehydrating and blocking, the co
ab80 at 1/300 staining mouse kidney (glomerulus) tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 45 minutes. An HRP conjugated goat anti-rabbit antibody was used as the secondary.
ab80 at 1/300 staining mouse brain cells by ICC/IF.
Paraformaldehyde fixation, Triton X-100 permeabilization, followed by blocking with 3% BSA + 2% NGS for 1 hour at 20°C.
Incubation with the primary antibody was carried out for 1 hour at 20°C. The secondary antibody was an Alexa Fluor® conjugated Donkey anti-Rabbit polyclonal, diluted 1/400.
ab80 staining CDKN2A/p19ARF in Mouse pancreatic neoplastic tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde and blocked with 5% serum for 1 hour at room temperature. Samples were incubated with primary antibody (1/100 in PBS) for 8 hours at 4°C. An Alexa Fluor®555-conjugated Donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody. Nuclei were stained by DAPI.
