NB100-2220

Lysates of HeLa parental cell line and LC3B knockout HeLa cell line (KO) untreated (-) or treated (+) with 50 uM CQ for 18 hours. PVDF (Polyvinylidene difluoride) membrane was probed with 0.5 ug/mL of Rabbit Anti-LC3B Polyclonal Antibody (Catalog # NB100-2220) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog# HAF008). A specific band was detected for LC3B at a molecular weight of approximately 15 kDa (as indicated) in the parental HeLa cell line, but is not detectable in the knockout HeLa cell line. GAPDH is shown as a loading control. This experiment was conducted under reducing conditions.

<b>Genetic Strategies Validation. </b>LC3B was detected in immersion fixed CQ treated HeLa cells (left) but was not detected in LC3B knockout HeLa cells (right) using rabbit anti-human LC3B polyclonal antibody (Catalog #NB100-2220) at 0.3 ug/mL for 3 hours at room temperature. Cells were stained using the NorthernLights(TM) 557-conjugated anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

HIF-1 alpha induction by CoCl2 on Caki-1 cell lysate. WB image submitted by a verified customer review.

<b>Biological Strategies Validation and Genetic Strategies Validation.</b>HIF-1 alpha was detected in immersion fixed DFO treated Hela cells (left) but was not detected in HIF-1 knockout HeLa cells (right) using Mouse Anti-human HIF-1 alpha monoclonal antibody (Catalog # NB100-105) at 25 ug/mL for 3 hours at room temperature. Cells were stained using a NorthernLights (TM) 557-conjugated Donkey Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

<b>Biological Strategies Validation and Genetic Strategies Validation.</b>Naive CD4 T cells from WT, VHL-deficient (Vhl KO), or HIF-1 alpha-deficient (HIF-1 alpha KO) mice were differentiated under IL-22-skewing conditions for a total of 60 h. Some cells remained at normoxia for the duration of the culture (N); others were at normoxia for 35 h and then hypoxia (1% O2) for 24 h (H). At 60 h, nuclear extracts were harvested, and HIF-1 alpha and Lamin B1 levels were analyzed by Western blot. Image from verified customer review.

<b>Biological Strategies Validation. </b>Normoxic pre-treatment sensitizes glioma cells to radiation after graded chronic hypoxic (GCH) exposure. The results of anchorage-independent colony forming assays are shown for U87, U87-luc, GL261 glioma cells and 0308 GSCs after 5 Gy radiation exposure under varying O2 conditions. For easier comparisons among cell types, raw values are expressed as a % of the cell type's negative (non-irradiated) control and the means & SEMs are plotted.

Western Blot: LC3A Antibody - BSA Free [NB100-2331] - Knockdown of FUT1 is associated with an increase in autophagic flux. (a) Immunoblot analysis of LC3-II & p62 levels in control & FUT1 knockdown cells. Total cell lysates from MCF-7 & T47D cells transfected with control or FUT1 siRNAs were collected at 120 & 96 h post-transfection, respectively. Equal amounts of cell lysates were then loaded in each lane & separated by SDS-PAGE. Immunoblot analysis was performed with LC3 & p62 antibodies. Actin was used as a loading control. The intensity of LC3-II & p62 protein bands on immunoblot were quantified & normalized to actin, & the relative levels of protein expression were expressed as fold change by setting the control group value to 1. Values shown are mean±S.E.M. of three independent experiments (***P100 cells per group (*P<0.05) Image collected & cropped by CiteAb from the following publication (//pubmed.ncbi.nlm.nih.gov/27560716), licensed under a CC-BY license.

Western Blot: LC3A Antibody - BSA Free [NB100-2331] - Tau clearance in vivo & autophagy function. Clearance kinetics of photoconverted Dendra-tau measured in neurons of WT-tau & AT152T-tau fish. Measurement of intensity of red Dendra-tau signal over time reflects the clearance or degradation of tau protein. (C–F) WBs for LC3-II, a well-characterized marker of autophagosome number, demonstrate that there no differences in levels of this protein between WT-tau & A152T-tau fish either at 24 hpf (pre-phenotype; C & D) or 72 hpf (post-phenotype; E & F). (E & F) Measurements of LC3-II levels in presence or absence of ammonium chloride provides a method for measuring autophagic flux. No differences observed between the two transgenic lines at 3 dpf, suggesting that autophagy functions normally in both WT-tau & A152T-tau fish (graph represents mean ± SD of four independent clutches per group for E & F & 3for C & D; two-tailed t-test).

The primary antibody bound to CAIX antigens in the tissue section was detected using a HRP labeled secondary antibody and DAB reagent. Nuclei of the cells were counterstained with hematoxylin. This CAIX antibody generated an expected cytoplasmic staining of CAIX protein with an intense signal around the cellular membranes in tumor cores. The latter are more likely to be hypoxic in growing tumors which signifies that the observed CAIX staining is specific.

Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the nuclei.

Simple Western: HIF-1 alpha Antibody (2443C) [NBP2-75978] - Lane view shows a specific band for HIF-1 alpha in HepG2 +/- DFO cell lysate using 20 ug/mL. Electropherogram image of corresponding Simple Western lane view at WES molecular weight of 116 KDa. Image from an internal validation.

Simple Western: HIF-1 alpha Antibody (2443C) [NBP2-75978] - Simple Western lane view shows lysates of MCF +/- DMOG, BioSpherix MSCs in hypoxic conditions, and BioSpherix MSCs in normoxic conditions loaded at 0.5 mg/ml. A band was detected for HIF-1 alpha at approximately 116 kDa (as indicated) using NBP2-75978 (1:100 dilution) followed by Anti-Rabbit Secondary Antibody (042-206, ProteinSimple). This experiment was conducted under standard assay conditions, and using the 12-230 kDa separation module (SW-W004). Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody. Image from an internal validation.
