Scientific Data Images for Human TOMM20 Antibody

Detection of TOMM20 in A549 Human Cell Line.

TOMM20 was detected in immersion fixed A549 human lung carcinoma cell line using Mouse Anti-Human TOMM20 Monoclonal Antibody (Catalog # MAB11604) at 8 µg/ml for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to the mitochondrion membrane. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Detection of Human TOMM20 by Western Blot.

Western Blot shows lysates of HeLa human cervical epithelial carcinoma cell line and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 2 µg/ml of Mouse Anti-Human TOMM20 Monoclonal Antibody (Catalog # MAB11604) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for TOMM20 at approximately 16 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of TOMM20 in Human Lung.

TOMM20 was detected in immersion fixed paraffin-embedded sections of human lung using Mouse Anti-Human TOMM20 Monoclonal Antibody (Catalog # MAB11604) at 5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm of bronchial epithelium.

Background: TOMM20

TOMM20 (Translocase of Outer Mitochondrial Membrane 20) is a receptor and key unit of the TOM complex.  The TOM complex translocates proteins produced from nuclear DNA through the mitochondrial membrane for use in oxidative phosphorylation.  TOMM20 is a conserved outer membrane protein and depletion of TOMM20 produces a large number of dysfunctional mitochondria with the loss of membrane potential.  Increased TOMM20 expression has been associated with malignancy of various cancers and contributes to tumorigenesis.
