Immunofluorescence analysis of NFkappaB / p65 was performed using 70% confluent log phase HeLa 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 NFkappaB / p65 Rabbit Polyclonal Antibody (Product # PA5-16758) at 2µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 (Product # 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.

PA5-16758 targets NFkappaB/p65 in IHC (P) and WB applications and shows reactivity with Human, Rabbit, and Rat samples.
The PA5-16758 immunogen is a synthetic peptide corresponding to internal domain of human NFkappaB p65.
NFkappaB is a heterodimer consisting of a 50kDa DNA binding subunit and a 65kDa transactivating subunit (RelA). The p50/p65 heterodimer is present in the cytoplasm in inactive form bound to its inhibitor, IkappaB. In unstimulated cells, nuclear localization signals present on p65 are masked by members of the IkappaB family of inhibitory proteins. Subsequent to cell stimulation, IkappaB undergoes phosphorylation, ubiquitination and degradation by a proteosome-dependent pathway, allowing nuclear translocation of the active dimeric NFkappaB transcription factor.

Pretreatment with mineralocorticoid receptor blocker reduces intestinal injury induced by ischemia and reperfusion: involvement of inhibition of inflammatory response, oxidative stress, nuclear factor κB, and inducible nitric oxide synthase.
PA5-16758 was used in immunohistochemistry to study the roles of oxidative stress, NFkB and iNOS in the mechanism by which pretreatment with a mineralocorticoid receptor blocker protects against ischemia-reperfusion-induced intestinal injury
