Application Abreviews Notes
WB 1/500 - 1/1000. Predicted molecular weight: 71 kDa.


  • Function

    Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.
  • Tissue specificity

    Expressed in platelets (at protein level).
  • Sequence similarities

    Belongs to the sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family. SLC6A4 subfamily.
  • Post-translational

    Glycosylated; modification with sialylated N-glycans is a requirement for transporters to associate with each other and to function as homooligomeric forms.
    Phosphorylated at Ser-611, Thr-613 and Thr-616.
  • Cellular localization

    Cell membrane. Endomembrane system. Endosome membrane. Translocates from intracellular locations to the plasma membrane. Density of transporter molecules on the plasma membrane is itself regulated by serotonin.

As long as the species and application are tested, you will get our Abpromise grantee over 180 days. that means in case the replacement doesn't work either, we'll refund you if you wish.

Please let me know about the alternative antibody of your choice.

I hope this information is helpful to you. I am looking forward to your reply.

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.

Thank you for your reply.

The images show different band sizes since the samples are different. One image shows a band at 75kda (as predicted). This image was generated with endogenous protein from mouse lung tissue lysate.

The other image was generated by overexpression of an ectopic Serotonin transporter protein and therefore the band is not depicting the predicted size.

I would like to assure you that ab102048 is tested and guaranteed with mouse samples for WB.

Thank you for your inquiry.

We have one antibody that is tested and guaranteed for WB and human and mouse samples:


https://www.abcam.com/index.html?datasheet=102048 (or use the following: https://www.abcam.com/index.html?datasheet=102048).

All other antibodies are tested and guaranteed only in human or mouse.

I can therefore recommend ab102048 for your experiments.

I hope this information is helpful and wish you good luck with your research.

Merci pour ces précisions.

Une suggestion que je n'ai pas mentionnée dans mon précédent email est d'essayer d'utiliser 5% de BSA comme agent bloquant à la place du lait. Pour certains anticorps la BSA permet un signal plus intense et une réduction significative du bruit de fond, exemple avec l'antiGAPDH ab9385 https://www.abcam.com/ab9385.

Une utilisation de l'anticorps à une dilution au 1/1000 au lieu de 1/500peut peut-être également permettre d'obtenir un blot plus propre.

J'espère que cesrecommandations vous seront utiles. N'hésitez pas à nous contacter de nouveau si vous avez d'autres questions.

Merci de nous avoir contactés.

A notre connaissance, la réactivité contre les bivalves n'a pas encore été testée avec l'anticorps ab102048. Toutes les informations sur les cross-réactivités d'espèces sont spécifiées dans notre fiche technique, et sont mises à jour régulièrement.

- La séquence de la SERT est-elle connue pour la moule ou plus généralement pour les bivalves? Si oui, il serait intéressant de déterminer le degré d'homologie de cette protéine avec la SERT humaine et ainsi déterminer les chances que l'anticorps reconnaisse la protéine de moule. Je pense que l'absence de détection de la SERT chez la moule s'explique par la faible homologie de séquence entre ces 2 espèces phylogéniquement très éloignées.

- J'ai regardé vos blots et je pense que l'anticorps fonctionne bien et reconnaîtspécifiquement la SERT humaine dulysat de placenta.

- Pour le second controle, la SERT n'est pas exprimée dans le sang, ce qui explique l'absence de bande à 71kDa. Voir le lien suivant pour l'expression de la SERT: http://www.ncbi.nlm.nih.gov/UniGene/ESTProfileViewer.cgi?uglist=Hs.134662. La bande à 50 kDa est peut-être due au secondaire. Il serait intéressant de faire un blot avec le secondaire uniquement, sans primaire, afin de vérifier cette hypothèse.

J'espère que ces informations vous seront utiles. N'hésitez pas à nous contacter de nouveau si vous avez d'autres questions.
