Scientific Data Images for Human Thioredoxin-1 Antibody

Detection of Human Thioredoxin-1 antibody by Western Blot.

Detection of Human Thioredoxin‑1 by Western Blot.

Western blot shows lysates of HEK293T human embryonic kidney cell line, HeLa human cervical epithelial carcinoma cell line, and MCF-7 human breast cancer cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Thioredoxin-1 Monoclonal Antibody (Catalog # MAB1970) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Thioredoxin-1 at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Thioredoxin-1 antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

Thioredoxin‑1 in HeLa Human Cell Line.

Thioredoxin-1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human Thioredoxin-1 Monoclonal Antibody (Catalog # MAB1970) at 3 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 cytoplasm.

Background: Thioredoxin-1

Thioredoxins (Trxs) are a group of small ubiquitous proteins in all living cells that are key regulators of cellular redox balance (1, 2). The mammalian Trx family has three members. The Trx-1, which is a secreted and cellular protein, the mitochondria-specific Trx-2, and the Trx-like cytosolic protein p32TrxL (3-5). The active site of mammalian Trxs contains two cysteines in the conserved sequence -Y-C-G-P-C-K-. In Trx-1 the conserved cysteine residues are in positions 32 and 35, respectively. Trxs exist either in a reduced or in an oxidized state when the two cysteines at the active site form an intramolecular disulfide bridge. NADPH and the flavoprotein thioredoxin reductase can convert the oxidized Trx into the reduced Trx. Trx-1 is the only extracellular occurring thioredoxin, and is secreted by lymphocytes, hepatocytes, fibroblasts, and several tumor cells. Plasma concentrations of Trx-1 are up to 6 nM (6). In cells, Trx-1 is localized predominantly in the cytoplasm. Small amounts have been detected in the nucleus and in association with the outside surface of the cells. Expression of Trx-1 is increased under various stress conditions such as hypoxia, elevated hydrogen peroxide concentrations, photochemical oxidative stress, and viral and bacterial infections. Biological functions of Trx-1 include growth factor activity, antioxidant properties, a cofactor that provides reducing equivalents, and transcriptional regulation (1, 2). The synovial tissue of rheumatoid arthritis patients produces increased levels of Trx-1 under oxidative stress conditions, and a correlation exists between the plasma levels of Trx-1 and the severity of the disease, making Trx-1 a biomarker for this pathological condition (7, 8).
