ターゲット情報

  • 機能

    Ubiquitinous metalloproteinase that is involved in diverse functions such as remodeling of the vasculature, angiogenesis, tissue repair, tumor invasion, inflammation, and atherosclerotic plaque rupture. As well as degrading extracellular matrix proteins, can also act on several nonmatrix proteins such as big endothelial 1 and beta-type CGRP promoting vasoconstriction. Also cleaves KISS at a Gly-
    -Leu bond. Appears to have a role in myocardial cell death pathways. Contributes to myocardial oxidative stress by regulating the activity of GSK3beta. Cleaves GSK3beta in vitro.
    PEX, the C-terminal non-catalytic fragment of MMP2, posseses anti-angiogenic and anti-tumor properties and inhibits cell migration and cell adhesion to FGF2 and vitronectin. Ligand for integrinv/beta3 on the surface of blood vessels.

  • 組織特異性

    Produced by normal skin fibroblasts. PEX is expressed in a number of tumors including gliomas, breast and prostate.

  • 関連疾患

    Defects in MMP2 are the cause of Torg-Winchester syndrome (TWS) [MIM:259600]; also known as multicentric osteolysis nodulosis and arthropathy (MONA). TWS is an autosomal recessive osteolysis syndrome. It is severe with generalized osteolysis and osteopenia. Subcutaneous nodules are usually absent. Torg-Winchester syndrome has been associated with a number of additional features including coarse face, corneal opacities, patches of thickened, hyperpigmented skin, hypertrichosis and gum hypertrophy. However, these features are not always present and have occasionally been observed in other osteolysis syndromes.

  • 配列類似性

    Belongs to the peptidase M10A family.
    Contains 3 fibronectin type-II domains.
    Contains 4 hemopexin-like domains.

  • ドメイン

    The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

  • 翻訳後修飾

    Phosphorylation on multiple sites modulates enzymatic activity. Phosphorylated by PKC in vitro.
    The propeptide is processed by MMP14 (MT-MMP1) and MMP16 (MT-MMP3). Autocatalytic cleavage in the C-terminal produces the anti-angiogenic peptide, PEX. This processing appears to be facilitated by binding integrinv/beta3.

  • 細胞内局在

    Secreted > extracellular space > extracellular matrix. Membrane. Nucleus. Colocalizes with integrin alphaV/beta3 at the membrane surface in angiogenic blood vessels and melanomas. Found in mitochondria, along microfibrils, and in nuclei of cardiomyocytes.

    Cells were grown on glass coverslips, treated with PMA and then fixed with 4% (w/v) paraformaldehyde in phosphate buffered saline (PBS). Samples were then permeabilized with 0.1% Triton X-100 in PBS and blocked with 5% (w/v) skimmed milk powder in PBS before staining with ab2462 and the appropriate secondary antibody, followed by washing and mounting.

    Scale bar: 10 µm.

Question


The KB cells are human cells.
I have stained the B actin very well and everybody here in my lab use the
same secondary antibody without any problem.
I do not think the problem is in the secondary antibody. I have talked with
some researches from other labs and they related the same problem with MMP
What do you think?

Read More
Answer

Thank you for confirming the quality of the secondary antibody. I can believe that the issue is with the MMP2 antibody but I am surprised that all three antibodies are giving you trouble.

Are the problems other people from other labs reporting about the same MMP antibodies from Abcam? Or just the MMP2 antibody?

If you are interested in trying a different MMP2 antibody, I will be happy to send a free replacement if your order is within the limits of our guarantee. Do you know when the order was placed, and the distributor

Question

I am using proteins extracted from KB cells using RIPA buffer. I am using 20
ul of antibody in 10 mL of TBST + 5% BSA: = 1/500. I am incubating the first ab
overnight (12 h). I have stained these samples with other ab and it is
working pretty good. Do you have any suggestion ?

Read More
Answer

Thank you for the protocol details.


Do the blots for MMP1 and MMP9 look similar to the MMP2 blot? Can you please tell me the species of KB cells?


I am a little concerned aboutthe quality of the sample, given the multiple bands between 50 and 75, and the smearing at the top of the wells. What is the protein that you are staining successfully? Are you using the same secondary for blots of that protein? Is there any possibility that the secondary antibody is the issue?


I look forward to your reply.

Question

I am using your Anit-MMP2 antibody (ab2462) and as you can see in the
attached figure, I am having a lot of cross-reactivity. As you specify in
the Instructions, this antibody only showed cross-reactivity with MMP-3.
Do you have any idea about what is happening ? I have used milk and BSA
to block (with milk blocking I have really bad results with a lot of
backgroundo). The attached figure is with BSA blocking buffer. The same
thing is happening with my ab2461 and ab3159.

Answer

Thank you for bringing this to our attention. Can you please describe your samples, how you prepare them for loading into the gel, how much antibody you use and how long you incubate, and any other details you think may be relevant? Are you confident the secondary antibody is effective and is not the source of the background? Have you stained blots of these samples with any other antibodies, and, if so, were the results as you expected?

Question

Phone call requesting information on the concentration of the Anti-MMP2 antibody [4D3] (ab2462).

Read More
Answer

Thank you for your enquiry.



Thank you for contacting us and sorry for the delay in getting back to you.



As discussed over the phone, unfortunately I can now confirm that the concentration of the Anti-MMP2 antibody [4D3] (ab2462) has not as yet been determined.



The concentration of unpurified antibodies, such as this one sold as tissue culture supernatant, will not have a concentration determined. Antibody concentration is usually determined by protein assay, and tissue culture supernatant will contain a lot of other proteins other than IgG, which means the antibody quantification would not be accurate.

I can however confirm that for tissue culture supernatant, concentration of antibody is known to very between 1 - 3 mg/ml.

I am sorry we are not able to provide an exact concentration on this occasion, but hope this information will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Answer

I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement for one vial of ab2462.
To check the status of the order please contact our Customer Service team and reference this number.
Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.
I wish you the best of luck with your research.

Question

What is the recommended dilution for using this tissue culture supernatant for IHC?

Read More
Answer

Thank you for your enquiry. We suggest a concentration of 1:20, however we also recommend a pilot experiment using a serial dilution with a range from 1:5 to 1:300 to determine the optimal concentration for the tissue you are staining. I hope this information helps. Please do not hesitate to contact us if you need any more advice or information.

Question

i have 2 questions regaring mmp2 ab2462. does it react against the pro and the active forms of mmp2. can i use placental tissue as positive control. thanks.

Answer

Thank you for your enquiry. This Ab reacts with both the pro- and cleaved form of MMP2. Placental tissue can be used as a positive control. Should you have any further questions then please do not hesitate to get back in touch with me.
