Catalase Antibody [Unconjugated]

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, Raji human Burkitt's lymphoma cell line, HeLa human cervical epithelial carcinoma cell line, NIH‑3T3 mouse embryonic fibroblast cell line, A20 mouse B cell lymphoma cell line, andRat‑2 rat embryonic fibroblast cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat Catalase Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF3398) followed by HRP-conjugated Anti‑Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Catalase at approximately 64 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 2.

Simple Western lane view shows lysates of Jurkat human acute T cell leukemia cell line and Raji human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Catalase at approximately 62 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse/Rat Catalase Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3398) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the12-230 kDa separation system.

Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and Catalase knockout HeLa cell line (KO). PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat Catalase Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3398) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Catalase at approximately 64 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Catalase was detected in immersion fixed HL‑60 human acute promyelocytic leukemia cell line using Goat Anti-Human/Mouse/Rat Catalase Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3398) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to peroxisomes. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background

Cells have evolved complex mechanisms to maintain redox balance and defend against oxidative stress. Catalase is a tetrameric enzyme comprised of four 60 kDa subunits. Catalase is typically localized in the peroxisome where it functions as an antioxidant, protecting cells from damage due to oxidative stress. Catalase converts reactive oxygen species, such as H₂O₂, into water and O₂. Human Catalase shares 89% homology to mouse and rat Catalase. The cells redox environment can serve as an important signaling switch or trigger to initiate a number of cellular processes, including gene expression, differentiation, proliferation and apoptosis.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
