  • Function
    Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation.
  • Tissue specificity
    Plasma, associated with HDL (at protein level). Expressed in liver, but not in heart, brain, placenta, lung, skeletal muscle, kidney or pancreas.
  • Involvement in disease
    Genetic variation in PON1 is associated with susceptibility to microvascular complications of diabetes type 5 (MVCD5) [MIM:612633]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Note=Homozygosity for the Leu-54 allele is strongly associated with the development of retinal disease in diabetic patients.
  • Sequence similarities
    Belongs to the paraoxonase family.
  • Post-translational
    The signal sequence is not cleaved.
    Present in two forms, form B contains a disulfide bond, form A does not.
  • Cellular localization

    Lane 1 : HeLa cell lysates.
    Lane 2 : HepG2 cell lysates.

    Predicted band size: 40 kDa

  • ab24261 (1µg/ml) staining PON1 in human liver using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining of hepatocytes.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH 6.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
  • Overlay histogram showing HepG2 cells stained with ab24261 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab24261, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HepG2 cells fixed with 100% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

  • ICC/IF image of ab24261 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab24261, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your phone call yesterday, and I apologize that we did not already have this information. I have heard back from the lab, and the buffer of ab24261 contains 10 mM HEPES. I hope this information is helpful, but please let me know if you have any further questions.

Sorry for the long wait. I have another update about one of the products you previously enquired. ab26930: We have not tested this product for cross reactivity with PON2 and PON3. ab24261: There is no reply from the originator and I would assume that they too have not tested the product for cross reactivity with PON2 and PON3. I am sorry I can't be of much help in this occasion but I hope that the information for ab92466 was sufficient for you to use the product in your research. If there is anything else that I can help you with, please do not hesitate to contact me.

I'm sorry to hear you are experiencing poor results with ab24261 in western blotting. Your protocol seems good in general and I have only a few suggestions which I help with resolve the problem: -As you are using a good positive control of HeLa cell lysate the problem does not seem to be low expression levels in this sample, however it would be worth trying a different lysis buffer as currently the buffer you use does not seem to be suitable for optimal extraction of the protein. I would therefore recommend using 20 mM Tris-HCl, pH 7.5, 1 mM EGTA and adding protease inhibitors to the buffer. Following lysis and centrifugation I would recommend to add reducing loading buffer to the supernatant and boiling for 5 min at 100C. -I am not familiar with the use of boric acid and EDTA in transfer buffers. We typically use a Tris transfer buffer made with 20% methanol and I would recommend to try this type of buffer. -it is good that you tried different blocking agents. Can I please make sure that you have tried blocking 1 hour only and incubating the antibody overnight in TBST only as sometimes the antibody binds the blocking agent rather than the membrane, if incubated too long together. -it would be worth checking that your transfer is working adequately by doing a Ponceau staining. I hope the suggestions above will help you. Please do not hesitate to contact me if those changes do not give you a better signal and I would be happy to offer you a replacement vial or refund if the antibody was purchased in the last 120 days.

Thank you for your enquiry. This product has been raised against the full length recombinant form of the target. I hope that this information helps.

Thank you for your enquiry. The antibody ab2461 has been tested in human samples of HeLa cell lysate and HepG2 cell lysate and in mouse samples on mouse liver tissue lysate on different gels therefore we cannot compare the amount of PON1 protein detected in those samples. In our hands the antibody works very well for both species, I hope this information will help you, please do not hesitate to contact me again if I can be of further assistance,
