Immunoprecipitation: HIF-1 alpha Antibody (H1alpha67) [NB100-123] - MG132 attenuates the inhibitory effect of interleukin-1beta on HIF-1/AM axis. U87MG cells were incubated for 2 h in hypoxia (1% O2) with or without interleukin-1beta (10 ng/ml). The proteasome inhibitor MG132 was added 30 min in advance to prevent ubiquitinated HIF-1alpha from proteasomal degradation. HIF-1alpha was precipitated by anti-HIF-1alpha antibody. Ubiquitin was detected by immunoblotting. Non-specific mouse IgG was used as a negative control. The results are representative for three independent experiments Image collected and cropped by CiteAb from the following publication (https://www.nature.com/articles/cddis2013562) licensed under a CC-BY license.

Western Blot: HIF-1 alpha Antibody (H1alpha67) [NB100-123] - Analysis using the HRP conjugate of NB100-123. On day 1, MEF cells (+/+,-/-), were grown on 15cm dish (2x10 to the 6th cells). On day 2, cells were exposed to hypoxia for 4hrs. Cells were washed with ice cold PBS twice and whole cell protein was extracted extracted with RIPA buffer fortified with protease. Upon quantification, 100ug of protein was fractionated on 7% polyacralymide gel. Gel was transferred overnight onto nitrocellulose membrane. The membrane was probed with HIF-1 alpha monoclonal antibody at a 1:500 dilution (NB100-123). The secondary antibody was conjugated with HRP and was used at a 1:2500 dilution.

Immunohistochemistry: HIF-1 alpha Antibody (H1alpha67) [NB100-123] - Schematic demonstration of the three HIF1 alpha antibodies used in this study & their epitopes (Figs. 2a & b). Ab1 is a polyclonal antibody raised against N-domain of wild type HIF1 alpha & does not recognize HIF1 alpha1.2 due to it's different N-terminal part (Fig. 2a). Ab2 & Ab3 are monoclonal & polyclonal antibodies, respectively, with epitopes in the common parts of HIF1 alpha & HIF1 alpha1.2 (Fig.2a & b). Immunohistochemical analysis performed on thin adjacent sections of NE-differentiated prostate cancer using the HIF1 alpha antibodies Ab1 (Fig. 2c), Ab 2 (Fig. 2d), Ab 3 (Fig. 2e) & HIF1 beta antibody (Fig. 2f). Immunopositivity was detected for HIF1 alpha with Ab2 & Ab3 while HIF1 alpha Ab1 produced no detectable staining. HIF1 beta was also positive in adjacent section (Fig. 2f). Double staining of chromogranin A & androgen receptor antigens on adjacent sections (Fig. 2g) showed immunopositivity for chromogranin A (Fast red). Androgen receptor antibody (DAB, brown) produced no staining. Immunostaining of benign prostate tissue with HIF1 alpha Ab3 showed immunopositivity in NE-like cells of benign prostate tissue (Fig. 2h). In addition, HIF1 beta antibody recognized benign NE-like cells in benign prostate hyperplasia (Fig. 2i). Double staining with HIF1 alpha Ab3 & HIF1 beta (Fig. 2j) shows co-localization of the two proteins in NE-like cells of benign prostate hyperplasia (HIF1 alpha Ab3 red stain, HIF1 beta brown stain).

(b,c) Representative western blot demonstrates a transient increase of HIF1 alpha expression in HX white matter at P18 with no significant effect at P11 (P=0.7955) & P45 (P=0.7333). Histograms show mean±s.e.m. (d,e) Graphs represent the percentages of Sirt1+Ki67+ & NG2+Ki67+ cells after HX white matter in WT & HIF1 alpha KO mice. Number in parentheses within bar indicates number of samples (n=4 brains per group & per genotype; ****P<0.0001, one-way analysis of variance, Bonferroni post hoc test, mean±s.e.m.). (f,g) Western blot demonstrates no increase (P=0.8231) in Sirt1 & HIF1 alpha expression in white matter of Hif1 alpha KO mice. Actin was used as loading control (mean±s.e.m.; n=3 brains for each experiment, group & genotype).
