    Broadly expressed with higher levels in liver and skeletal muscle.
  • Sequence similarities
    Belongs to the anoctamin family.
  • Domain
    The region spanning the fifth and sixth transmembrane domains probably forms the pore-forming region.

  • ab53213 staining TMEM16A in human gastrointestinal stromal tumor sections by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
    Tissue was fixed in formaldehyde and a heat mediated antigen retrieval step was performed using citrate pH 6.0. Samples were then incubated with undiluted ab53213 for 20 minutes at 25°C. The secondary used was an undiluted HRP conjugated goat anti-rabbit polyclonal.

Thank you very much for your reply and for keeping me update.

I'm sorry to hear that this antibody still did not work after modifying the protocol. I'd be happy to send a replacement with a different antibody or issue a credit or refund. Please let me know which option you'd like to accept and send me your original PO or order number, and I'll arrange it for you promptly.

I look forward to hearing from you. If there is anything else that we can do for you, please let me know and I'll be happy to help.

Thank you for your reply and for kindly providing the word document. This has made conducting the alignments much more straight forward.

I am sorry to confirm that as far as we are aware,none of our TMEM16A antibodieshas been tested with samples from Zebrafish. All tested species covered by the 6 month guarantee are stated on our datasheets, and these are updated as soon as any new information is brought to our attention.

I have obtained the immungoen sequences for all our TMEM16A antibodies and checked the alignment of these with the 3 Zebrafish sequences you provided.

Regrettably, for most of these the alignments are too low for us to suggest they may detect in Zebrafish. However, there is one with reasonable alignment that you may like to consider trying. I can recmomend to review the online datasheet for further information.

https://www.abcam.com/index.html?datasheet=84115 (or use the following: https://www.abcam.com/index.html?datasheet=84115).

Immunogen: ################

Alignment with Zebrafish sequences provided:
Sequence 1: 68%
Sequence 2: 68%
Sequence 3: 72%

We recommend alignment should be over 85% to predict that an antibody will detect. It isstill possible that with 68-72% alignment therecould be some crossreactivity. However, even when alignmentis very highwe cannot guarantee this without further testing.

If you would like to test the ab84115 in Zebrafish, please contact me again by replying to this message prior to the purchase as you may be eligible for our testing discount program.

Otherwise, we like to encourage all of our customers to submit an Abreview via the online product datasheet. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as Amazon.com gift certificates.

Je suis désolée d'apprendre que vous avez eu des problèmes avec le lot GR27833-1 ainsi que avec le Western blot sur tissu/cellules de souris.
Si vous souhaitez que nous regardons et investiguons ce problème ensemble, veuillez s'il vous plaît nous transmettre vos conditions expérimentales. Veuillez trouver ci-joint le questionnaire qui nous permet de regrouper le plus d'informations possible sur le protocole que vous avez utilisé avec cet anticorps.
Pour les résultats Western blot, j'ai juste trouvé ces images qui sont en lien sur la fiche technique aussi:
Western blot sur du tissue du souris:
Western blot sur du tissue du souris, bandes coupées:
Western blot sur du tissue de souris ainsi que description de splice variants dans des différents tissues.
Effectivement, aussi dans UniProt, trois différents isoformes de TMEM16A sont décrits . Les formes sont à 74kD, 98kD ainsi que 114kD.
Comme TMEM16A est une protéine avec plusieurs parties transmembranaires, nous recommandons de chauffer les lysats que à 70°C pour la dénaturation avant mis sur le gel, car autrement il y peut avoir dégradation.
J'espère que ces informations vous sont utiles. N'hésitez pas à nous recontacter, si vous souhaitez discuter les résultats en plus de détails ou si vous avez des autres questions.
Comme aussi discuté au téléphone, nous n'avons malheureusement pas les mêmes lots en stock. Je tiens à vous rassurer, que nous garantissons tous nos produits de fonctionner comme décrit sur la fiche technique. Voici le lien pour plus d'information sur notre garantie: www.abcam.com/abpromise
Je vous souhaite une très belle journée.
