Application Abreviews Notes
IP Use at an assay dependent concentration.

ICC/IF Use at an assay dependent concentration.


  • Function

    Essential transmembrane GTPase, which mediates mitochondrial fusion. Fusion of mitochondria occurs in many cell types and constitutes an important step in mitochondria morphology, which is balanced between fusion and fission. MFN1 acts independently of the cytoskeleton. Overexpression induces the formation of mitochondrial networks.
  • Tissue specificity

    Ubiquitous. Expressed at slightly higher level in kidney and heart. Isoform 2 may be overexpressed in some tumors, such as lung cancers.
  • Sequence similarities

    Belongs to the mitofusin family.
  • Post-translational

    Ubiquitinated by MARCH5.
  • Cellular localization

    Cytoplasm and Mitochondrion outer membrane.

I believe there has been a misunderstanding here.

We try to provide all the information which we have regarding any product we carry and provide the most thorough data we can on our datasheets as you have undoubtably seen when using our Mitofusin 2 antibody. Our products made in house will invariably have that information available as well. We do have over 70,000 products on our catalog and this data is available to many of those products. However, we also receive a number of products from outside suppliers. Some of these products will have licensing agreements which preclude providing detailed immunogen sequences. In these instances we try and provide a range within immunogen protein against which the antibody is made.

I hope this information helps you to understand our previous communication. Please let me know if you have any further questions or concerns.

Thank you very much for your interest in our Mitofusin 1 antibodies.

Unfortunately the exact sequences of many of the immunogens used to create our proprietary. I have BLAST-ed the human and mouse Mitofusin 1 sequences and found that the identities between those species and dog were 91% and 94% respectively.

To our knowledge, these products have not been tested in dog tissues. Therefore, I can offer a discount off a future purchase if you purchase now, test it in dog tissue and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of 1 free PRIMARY ANTIBODY.

As you are interested in WB and IHC-P may I recommend one of the following products as they have both been shown to work in those applications?



If you are interested in this offer, please follow these steps:

1. Reply to this e-mail to let me know which antibody against Mitofusin 1 you would like to proceed and test. I will then send a discount code. This code must be issued before purchasing so please wait for my reply before ordering.

2. Purchase either by phone, fax, or online (www.abcam.com).

3. Test it in dog tissue.

4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!). To find out how to submit an Abreview, please visit: https://www.abcam.com/abreviews.

5. After the review is submitted to us, the discount code becomes active. Simply place your new order by phone, fax, or on the web and mention the discount code. The discount can be redeemed for any PRIMARY ANTIBODY ordered and the discount code is valid for 4 months after issue.

We are always pleased to obtain feedback about our products and any information is greatly appreciated! Even if the antibody) turns out to be unsuitable for this species, you will still receive the discount on your next purchase after your Abreview has been submitted.

Please let me know if you have any questions about this offer and I would be happy to help you further.
