  • Function

    Complexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. May form part of a tissue-specific acute response to remodeling stimuli. Known to act on MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-13, MMP-14 and MMP-15.
  • Involvement in disease

    Defects in TIMP3 are the cause of Sorsby fundus dystrophy (SFD) [MIM:136900]. SFD is a rare autosomal dominant macular disorder with an age of onset in the fourth decade. It is characterized by loss of central vision from subretinal neovascularization and atrophy of the ocular tissues. Generally, macular disciform degeneration develops in the patients eye within 6 months to 6 years.

  • ICC/IF image of ab39185 stained HeLa cells. The cells were 100% methanol fixed (5 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 (ab39185, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.

  • Ab39185 staining Human normal placenta. Staining is localized to the cytoplasm or excreted.
    Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer citrate EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, 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 we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Thank you for contacting us.
I have checked, but unfortunately, for these antibodies we do not have more immunogen information than what is on the datasheet. The source where we receive these 3 antibodies from, considers any immunogen information proprietary and therefore we do not have this information ourselves.
I'm very sorry about this. I know this will be very disappointing for you, but I wish I could be of more help.
Please do not hesitate to contact us if you need any more advice or information.

Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from these antibodies. The details you have kindly provided will enable us to investigate this case for you and also gives us vital information for our monitoring of product quality. 1) When testing our antibodies, our lab uses 5% BSA as a blocking reagent, so I recommend switching to this instead of milk. For unknown reasons some antibodies give stronger, more specific signals on blots blocked with BSA instead of milk, so doing this may improve the results you are seeing, and reduce the non-specific bands. An example of the above is the western blot obtained with the Abcam GAPDH antibody ab9385 : Click here for the western blot image using ab9385 (or use the following: www.abcam.com/ab9385).   2) I am unsure if the bands you are observing are around 80 kDa, as the resolution of the higher molecular weight marker bands is suboptimal. In case no bands have run out of the gel and you count from the bottom, the TIMP3 bands could also be around 60 kDa. If that is the case they may represent multimers of the protein (32 kDa dimers were reported according to the literature) or complexes with metalloproteinases. Therefore, I would recommend boiling the samples for more than 5 minutes (e.g. 10min) which may help to reduce disulfide bridges and break up complex structures. We are happy to offer this technical support. In the event that the product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund. I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details.

Thank you for providing the additional information and western blot data. It appears that ab39185 detects a protein of the expected molecular weight in the conditioned medium however the 50kDa band is seen in the OVC tissue extracts. And the band in the OVC samples seems to be quite specific. I have found TIMP3 can form dimers but, as I've found, only regarding the following: "Mutations to TIMP-3, all of which introduce an extra cysteine residue into exon 5 (which forms part of the COOH-terminal domain of the molecule), have been linked to the macular degenerative disease Sorsby’s fundus dystrophy" in: The Journal of Biological Chemistry, 273, 16778-16781. Also we do not have free samples available.

Thank you for your enquiry. Just a few additional questions regarding your western blot: 1. Have you used any other antibodies for western blotting with this ovarian cancer tissue extract? If so, what were the results? 2. The 50kDa band you see may be a TIMP3 dimer. Have you proped any other human or mouse tissue or cell lysates with ab39185 as a comparison? 3. It might be helpful to view your results. If you could, please forward along an image of your western blot. Thanks very much for the additional information.
