Immunofluorescence analysis of p73 alpha/beta was performed using 70% confluent log phase MCF-7 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with p73 alpha/beta Antibody (ER-15) Mouse Monoclonal Antibody (MA514117) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

MA5-14117 targets p73alpha/beta in IP and WB applications and shows reactivity with Human and Non-human primate samples.
The MA5-14117 immunogen is purified monkey recombinant p73alpha protein (aa380-637).
p73 exhibits sequence homology to the p53's transcriptional activation, DNA binding, and oligomerization domains. However, adenovirus E1B 55K, simian virus 40 T, and human papillomavirus E6 do not physically interact with p73 indicating that the functions of these two proteins may differ under physiological conditions. p73 is expressed in either a full-length form (alpha) (MW ~80kDa) or a shorter (beta) (MW ~70kDa) mRNA variant, with exon 13 spliced out. Transient overexpression of p73 in cells can induce apoptosis and p21, a cellular p53 target gene primarily responsible for p53-dependent cell cycle arrest.
