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.

MAB701

Ubiquitin/Ubiquitin+1 was detected in immersion fixed paraffin-embedded sections of human Alzheimer's disease brain (cortex) using 25 µg/mL Mouse Anti-Human Ubiquitin/ Ubiquitin+1 Monoclonal Antibody (Catalog # MAB701) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of neurons in the cortex. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Western blot shows samples of Recombinant Human Ubiquitin (Catalog # 701-UB) (2, 1, and 0.5 ng) and Recombinant Human Ubiquitin+1 (Catalog # 703-UB) (2, 1, and 0.5 ng). PVDF membrane was probed with 1-2 µg/mL Mouse Anti-Human Ubiquitin/Ubiquitin+1 Monoclonal Antibody (Catalog # MAB701) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands for Ubiquitin and Ubiquitin+1 were detected at approximately 11 kDa and 13 kDa, respectively (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 9.
