We performed Western blot analysis of erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO1) proteins in homogenates derived from irradiated EpidermFT tissues (Fig. 3). Nuclear and cytoplasmic proteins were fractionated and Nrf2 was probed in the nuclear fraction using rabbit anti-Nrf2 antibody (1:250) and the housekeeping gene histone H3 was probed using rabbit anti-histone H3 antibody (1:3,000) (both from Abcam®, Cambridge, MA). HO1 was probed in the cytoplasmic fraction using rabbit anti-HO1 (1:500; Enzo Life Sciences Inc., Farmingdale, NY) and GAPDH was detected using mouse anti-GAPDH antibody (1:5,000; Thermo Fisher Scientifice™ Inc., Waltham, MA). The secondary antibody used was anti-rabbit monoclonal (1:5,000; GE Healthcare Bio-Sciences, Pittsburgh, PA) or anti-mouse monoclonal (1:5,000).
We performed Western blot analysis of heme oxygenase 1 (HO1) protein in homogenates derived from nonirradiated EpidermFT tissue (Fig. 4). Dermaprazole (1–2%) was applied on the tissue topically and the viable EpidermFT tissue was incubated at 378C/5% CO2 for 24 h. HO1 was probed using rabbit anti-HO1 (1:500; Enzo Life Sciences) and GAPDH was detected using mouse anti-GAPDH antibody (1:5,000; Thermo Fisher Scientific). The secondary antibody used was anti-rabbit monoclonal (1:5,000; GE Healthcare).

Protein extracts were prepared with cytoplasmic lysis buffer (25mM Tris-HCl [pH7.4], 40mM KCl, and 1% Triton X-100) supplemented with 1 mg/ml aprotinin and 1 mg/ml leupeptin (all obtained from Sigma). Twenty micrograms of total protein was run on 10%−15% SDS-polyacrylamide gels, and Western blotting was performed exactly as described (Theurl et al., 2006 (link)) with a mouse anti-human TfR1 antibody (1:1000; Invitrogen), rabbit anti-human Ferritin (1:500; Sigma), rabbit anti-Fpn (1:400; self designed; Eurogentic), rabbit anti-HO-1 (1:1000; Enzo), rabbit anti-iNOS (1:1000; BD), rabbit anti-NFκB p65 or rabbit anti-phosphor NFκB p65 (both 1:1000; Cell Signalling). Blotting with either rabbit anti-TBP (1:1000; Cell Signalling) or rabbit anti-Actin antibody (1:1000; Sigma-Aldrich) was performed as a loading control.

Mtb expressing mCherry was grown in 7H9 media to log phase and then
fixed in 4% paraformaldehyde for 30 minutes. Fixed Mtb was then
incubated with primary antibodies against Mtb (rabbit anti-Mtb), HO1 (rabbit
anti-HO1; Enzo Life Sciences) or rabbit IgG all at a 1:100 dilution. Then, an
Alexa 488 conjugated donkey anti-rabbit secondary (1:500, A21206, Life

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
