Scientific Data Images for Human PON2 Antibody

Detection of Human PON2 antibody by Western Blot.

Detection of Human PON2 by Western Blot.

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Human PON2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4344) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for PON2 at approximately 42-45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Detection of PON2 by Western Blot

Characterization of ID8EV and ID8hPON2 cells. A) Expression of hPON2 protein was analyzed by western blotting in ID8EV and ID8hPON2 stable cell lines. b) ID8EV and ID8hPON2 cell fractions were subjected to western blotting for PON2 and COX IV proteins. c) Colocalization of mitochondrial marker and PON2. ID8EV and ID8hPON2 cell were fixed and stained with Mito Tracker® Red (a mitochondrial marker, red) and PON2 antibody (green). The merged image of hPON2 and mitochondria (yellow) is shown in the bottom panel. d) Colocalization of ER marker and PON2. ID8EV and ID8hPON2 cell were fixed and stained for Calnexin (green), an ER marker, and hPON2 (red). The merged image of hPON2 and Calnexin is shown in the bottom panel. e) Mitochondria were isolated from ID8EV and ID8hPON2 cells and respiratory complex II + III assay was carried out as described in Materials and methods section. The results are expressed as Cytochrome c reduced/min/mg protein. f) mitochondrial superoxide levels were measured as described in the methods  and values were expressed as fold change over the ID8EV. *p < 0.05 compared to IDEV cells. g) ID8EV and ID8hPON2 cells were cultured for 48 h, serum starved for 12 h, and cell viability was measured as described in the method section. h) 5 × 103 ID8EV and ID8hPON2 cells were cultured for 48 h, serum starved for 12 h and cell proliferation was assessed using BrdU by spectrophotometry as described in the Materials and methods section Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/29531225), licensed under a CC-BY license.

Background: PON2

The paraoxonase (PON) gene family of antioxidant enzymes includes three known members located adjacent to each other on chromosome 7. Paraoxonase/arylesterase 2 (PON2) is a 354 amino acid, 39 kDa protein that is widely expressed in a variety of tissues and may act as a cellular antioxidant, protecting cells from oxidative stress. PON2 has arylesterase and aryldialkylphosphatase activity (EC 3.1.1.2 and EC 3.1.8.1) and can hydrolyze a number of organophosphate substrates and aromatic carboxylic acid esters. PON2 is membrane-bound and has several potential glycosylation sites. Sequence polymorphisms in this gene may be associated with coronary heart disease and a number of phenotypes related to diabetes. PON2 is not associated with HDL but can prevent LDL lipid peroxidation and reverse the oxidation of mildly oxidized LDL. Alternatively spliced transcript variants encoding different isoforms have been described.
