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.

Whereas it could have been possible that reduced GamGFP recruitment in the presence of Ku was caused by reduced persistence of DSBs due to their repair by NHEJ, our data show instead that Ku inhibits recruitment independently of successful NHEJ & imply that Ku binding to DSEs itself is inhibitory.DOI://dx.doi.org/10.7554/eLife.01222.014 Image collected & cropped by CiteAb from the following publication (//elifesciences.org/articles/01222), licensed under a CC-BY license.

(B) GamGFP co-localizes with gamma H2AX in fixed Hela cells.DOI://dx.doi.org/10.7554/eLife.01222.013Ku inhibits GamGFP recruitment at DSBs independently of non-homologous end joining.Cells lacking either Ku80 or LigIV are defective in non-homologous end joining (NHEJ), yet the presence of Ku still inhibits recruitment of GamGFP to laser-induced DSBs even in NHEJ-defective cells, & thus independently of the cell's ability to complete NHEJ. Whereas it could have been possible that reduced GamGFP recruitment in the presence of Ku was caused by reduced persistence of DSBs due to their repair by NHEJ, our data show instead that Ku inhibits recruitment independently of successful NHEJ & imply that Ku binding to DSEs itself is inhibitory.DOI://dx.doi.org/10.7554/eLife.01222.014 Image collected & cropped by CiteAb from the following publication (//elifesciences.org/articles/01222), licensed under a CC-BY license.

Immunocytochemistry/ Immunofluorescence: 53BP1 Antibody - BSA Free [NB100-304] - Detection of 53BP1 in CTCs from MBC patients in the DETECT IV trial. (a) Selection of MBC patients with CTC-positivity (HER2-) & primary TNBC or primary HER2-, HR+ breast cancer for Eribulin monotherapy & blood sample collection. Blood samples were drawn before therapy (baseline visit), four, twelve, & 24 weeks after the start of Eribulin treatment (1st, 2nd, & 3rd treatment visit) as well as one year after treatment initiation or during premature termination due to disease progression (final visit). The numbers of patients recruited at the different visits are indicated by black columns, the numbers of CTC+ & CTC- patients among them by red & grey columns, respectively. Note that not all of the patients described in Table 1 entered the study during the baseline visit but during later visits which explains the differences in patient numbers. (b) Evaluation of 53BP1 signals in CTCs. Following EpCAM-based CTC enrichment & immunofluorescence microscopic imaging (Cellsearch®), CTCs (CK+, CD45-) were enumerated & 53BP1-staining intensity assessed per individual CTC as indicated by representative examples.

Simple Western: beta-Actin Antibody (AC-15) [NB600-501] - iPSC-RPE from an ARB donor show reduced levels of Best1 expression compared to five different iPSC-RPE control lines. (A) To compare Best1 protein expression levels between different iPSC-RPE lines, beta -actin was used as a loading control. (B) While iPSCs displayed no detectable Best1 protein expression, all shown iPSC-RPE lines – regardless of donor origin – displayed detectable Best1 protein expression. (C) The three control iPSC-RPE lines derived from unrelated, unaffected donors all exhibited similar levels of Best1 protein expression. The dad exhibited reduced levels compared to the unrelated controls & the mom showed levels that were about 50% that of the dad. This was expected as the antibody used cannot detect the mutant Best1I366fsX18 which both the mom & the ARB patient are heterozygous for. Best1 expression levels in the ARB iPSC-RPE line were about a quarter of the levels observed in the Mom 214 iPSC-RPE clone. (D) Widefield immunofluorescent staining of Best1 reveals basolateral staining in each of the iPSC-RPE lines, indicating that Best1 protein is properly localized regardless if Best1R141H and/or Best1I366fsX18 are present. Immunofluorescent signal was notably weaker in the ARB iPSC-RPE clones than in the control clones.

EPS15 is targeted via a SPOP/SPOPL binding consensus motif.(A) Cartoon of human EPS15 domain-organization and the amino-acid sequence. Indicated by color code are the SPOP/SPOPL binding site (red) and the lysine residue (yellow), which is ubiquitinated in a CRL3SPOPL–dependent manner in vivo. In addition, the amino-terminal Ca2+-binding EF-hand motifs (EH), the coiled-coil domain involved in dimerization and the two carboxy-terminal ubiquitin-interacting motifs (UIMs) involved in ubiquitin-binding are indicated. (B) EPS15 ubiquitin-profiling. Peptides containing EPS15 modification sites were quantified with LC-MS/MS after enrichment of the K-epsilon -GG motif from whole cell digests of HeLa cells treated with siSPOPL or siControl. Normalized precursor mass intensity profiles for EPS15 sites corresponding to K793, K801 and K693 are shown (raw data in Figure 4—figure supplement 1B).

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).

Simple Western: ATG5 Antibody - BSA Free [NB110-53818] - Dose-responses of Mn on cell viability and autophagy flux. (A) Stable HeLa cells overexpressing mRFP-GFP-LC3, and immortalized rat dopaminergic neuronal cells N27 were exposed to MnCl2 (62.5 uM to 2mM) for 24h, or (B) 48h. Cell viability was evaluated using Calcein AM dye. Data represent mean +- SEM, n = 3 independent experiments with 4 replicates per experiment. (C) Schematic diagram illustrating the autophagy flux pathway and the construct used to create the mRFP-GFP-LC3 stable HeLa reporter cells. With this cell model, autophagosomes appear yellow due to the colocalization of RFP and GFP signals. Red signal indicates the flux is functional because the green signal is quenched by the acidic environment of the lysosomes, which fuse with autophagosomes. These stable cells were treated with vehicle control or Mn (15.6-250 uM) for 24h. (D) Representative images of cells treated with different doses of Mn were captured using confocal microscopy. (E) Green and red vesicles per cell were quantified using Fiji. Green vesicles represent autophagosomes. The number of autolysosomes was calculated by subtracting the number of green from the red puncta per cell. Scale bar = 20um. (F) Stable HeLa cells were treated with MnCl2 (125 uM), chloroquine (CQ) or both. (G) The number of autophagosomes and autolysosomes were quantified. The combination of Mn with CQ did not significantly alter the numbers of autophagosome (P = 0.9941) and autolysosome(P > 0.9999), as compared to CQ (50 uM) only, a dose that did not completely inhibit autophagy. Data represent mean +- SEM. (H) N27 cells were treated with 62.5 or 125 uM of MnCl2 for 24h, then incubated with LysoSensor Yellow/Blue. The ratio of acidic (yellow) vs. neutral (blue) pH of lysosomes were quantified using a plate reader. (I) N27 cells were treated with Mn 125 uM, CQ50 uM or both for 24h, followed by immunoblotting for Atg5, a marker for autophagosomes, using Jess (Protei
