  • Function

    Hydrolyzes lysophospholipids to produce lysophosphatidic acid (LPA) in extracellular fluids. Major substrate is lysophosphatidylcholine. Also can act on sphingosylphosphphorylcholine producing sphingosine-1-phosphate, a modulator of cell motility. Can hydrolyze, in vitro, bis-pNPP, to some extent pNP-TMP, and barely ATP. Involved in several motility-related processes such as angiogenesis and neurite outgrowth. Acts as an angiogenic factor by stimulating migration of smooth muscle cells and microtubule formation. Stimulates migration of melanoma cells, probably via a pertussis toxin-sensitive G protein. May have a role in induction of parturition. Possible involvement in cell proliferation and adipose tissue development. Tumor cell motility-stimulating factor.
  • Tissue specificity

    Predominantly expressed in brain, placenta, ovary, and small intestine. Expressed in a number of carcinomas such as hepatocellular and prostate carcinoma, neuroblastoma and non-small-cell lung cancer. Expressed in body fluids such as plasma, cerebral spinal fluid (CSF), saliva, follicular and amniotic fluids. Not detected in leukocytes. Isoform 1 is more highly expressed in peripheral tissues than in the central nervous system (CNS). Adipocytes only express isoform 1. Isoform 3 is more highly expressed in the brain than in peripheral tissues.
  • Sequence similarities

    Belongs to the nucleotide pyrophosphatase/phosphodiesterase family.
    Contains 2 SMB (somatomedin-B) domains.
  • Post-translational

    N-glycosylation, but not furin-cleavage, plays a critical role on secretion and on lysoPLD activity.
  • Cellular localization

    Secreted. Secreted by most body fluids including serum and CSF. Also by adipocytes and numerous cancer cells.

  • All lanes : Anti-HTR3C antibody (ab85290) at 1 µg/ml

    Lane 1 : Human ovary tissue lysate - total protein (ab30222)
    Lane 2 : Human small intestine tissue lysate - total protein (ab29276)

    Lysates/proteins at 10 µg per lane.

    All lanes : Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 99 kDa
    Observed band size: 110 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 55 kDa, 70 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 20 minutes

    ENPP2/ATX contains three potential glycosylation sites (SwissProt), which might explain its migration at a higher molecular weight than predicted.

  • ICC/IF image of ab82590 stained SKNSH cells. The cells were 4% formaldehyde 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 (ab82590, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 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 enquiry.

I am sorry to confirm that these antibodies have not been tested in sandwich ELISA (sELISA). They have been tested in indirect ELISA only and I can recommend considering using them in an indirect ELISA rather than sELISA.

Sandwich ELISA procedures can be difficult to optimise and tested match pair antibodies should be used. Any tested matched pairs would be noted on the datasheet. This ensures the antibodies are detecting different epitopes on the target protein so they do not interfere with the other antibody binding. Therefore, I am sorry we are unable to guarantee our antibodies in sandwich ELISA unless they have been specifically tested for sandwich ELISA.

I am sorry I am unable to suggest any other antibodies suitable for sandwich ELISA for you on this occasion. However, I hope this information is helpful, Should you have any further questions, please do not hesitate to contact us.

Thank you for contacting us. Ab82590 and ab77104 are both Anti-ENPP2 mouse monoclonals, however,  ab82590 is from the clone [1F8] and ab77104 is from [5H3]. We are sorry if any confusion has been caused in this matter. We have no plans to discontinue either product. I am sorry to hear you have been experiencing problems with ab82590. This antibody has been tested using mouse and human samples and in paraffin embedded IHC. We would therefore expect your experiments to be working. If you wouldn't mind, could you please fill out the questionnaire I have attached in order to find out a few more details about the protocol used. This may allow me to suggest some things in order to improve the result, and will also allow us to monitor the problem and initiate any internal investigations needed in this case. If the antibody was purchased within 6 months and used according to the datasheet you will be covered by the Abpromise and will be entitled to a free of charge replacement or a credit note. I look forward to receiving your reply.

I am sorry to report that we have no IHC image for this antibody. It was apparently tested by a collaborator who reported that it was effective for IHC, but we never received an image. If you are having trouble with the antibody in this application, please contact us.
