  • Function
    Seems to be required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. May act by competing with the putative neuronal protein kinase DCAMKL1 in binding to a target protein. May in that way participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. May be part with LIS-1 of an overlapping, but distinct, signaling pathways that promote neuronal migration.
  • Tissue specificity
    Highly expressed in neuronal cells of fetal brain (in the majority of cells of the cortical plate, intermediate zone and ventricular zone), but not expressed in other fetal tissues. In the adult, highly expressed in the brain frontal lobe, but very low expression in other regions of brain, and not detected in heart, placenta, lung, liver, skeletal muscles, kidney and pancreas.
  • Involvement in disease
    Defects in DCX are the cause of lissencephaly X-linked type 1 (LISX1) [MIM:300067]; also called X-LIS or LIS. LISX1 is a classic lissencephaly characterized by mental retardation and seizures that are more severe in male patients. Affected boys show an abnormally thick cortex with absent or severely reduced gyri. Clinical manifestations include feeding problems, abnormal muscular tone, seizures and severe to profound psychomotor retardation. Female patients display a less severe phenotype referred to as 'doublecortex'.
    Defects in DCX are the cause of subcortical band heterotopia X-linked (SBHX) [MIM:300067]; also known as double cortex or subcortical laminar heterotopia (SCLH). SBHX is a mild brain malformation of the lissencephaly spectrum. It is characterized by bilateral and symmetric plates or bands of gray matter found in the central white matter between the cortex and cerebral ventricles, cerebral convolutions usually appearing normal.
    Note=A chromosomal aberration involving DCX is found in lissencephaly. Translocation t(X;2)(q22.3;p25.1).

Vielen Dank für Ihre Antwort. Ich habe Ihnen einen Anti-Doublecortin Antikoerper aus der Ziege herausgesucht. Click here (or use the following: https://www.abcam.com/index.html?datasheet=113435). Doublecortin färbt keine Glia -Zellen an (siehe Paper im Anhang). Allerdings wird es am stärksten im Neonatalen Gehirn expremiert. Wenn die Zellen aus einem alteren Tier stammen, kann das Signal dementsprechend schwächer sein. Unseres Wissens nach wurde der ab113435 bisher noch nicht in ICC getestet. Falls Sie dies selbst testen möchten, kann ich Ihnen zur Zeit ein spezielles Angebot über einen 100%igen Abreview-Rabatt anbieten. Bei diesem Angebot bekommen Sie einen Rabatt für eine zukünftige Bestellung, wenn Sie uns ein Abreview mit dem Testresultat zusenden. Der Rabatt würde den ganzen Wert von ab113435 abdecken, und gegen eine erneute Bestellung eines weiteren primären Antikörpers von uns verrechnet werden. Um von diesem Angebot profitieren zu können, folgen Sie bitte diesen Schritten: 1.) Bestätigen Sie mir bitte, dass Sie ab113435 in ICC testen möchten. 2.) Bitte bestellen Sie erst nach Erhalt des Rabattcodes. 3.) Bestellen Sie den Antikörper wie üblich per Telefon, Email oder Fax 4.) Testen Sie den Antikörper in ICC. 5.) Teilen Sie uns das Ergebnis Ihres Tests durch ein Abreview mit und notieren Sie den Discount Code in dem Feld "additional notes" Unter der folgenden URL können Sie mehr über unser Abreview System erfahren: https://www.abcam.com/abreviews 6.)

Thank you for getting back to me with those details.
As I have mentioned previously, we have not performed any IHC experiments with this antibody, we would therefore not be sure of how well it would perform in this application.
You mentioned on the phone that one of your colleagues had used a Doublecortin antibody for IHC. Were you able to confirm that it was ab113435?
Having reviewed the protocol you have been using there are a few suggestions I can make which may help to improve the results obtained.
1. You have used PFA to fix the tissue. This may mean that some form of antigen retrieval is required which can be very tricky with brain tissue. In order to avoid this you could fix the tissue in a different fixative such as acetone, methanol or ethanol. Otherwise it may be worth having a look at the following reference for antigen retrieval of frozen sections:
Yamashita S, Okada Y. Application of heat induced antigen retrieval to aldehyde fixed fresh frozen sections. J. Histochem Cytochem. 2005 Nov;53(11):1421-32.
2. I would suggest performing a "no primary" control alongside with the normal staining to see if the secondary antibody is contributing to the non-specific binding. It may also be worthwhile to reduce the concentration of secondary antibody.
3. I would reduce the concentration of hydrogen peroxide used to block the endogenous peroxidases to 0.3 % and it may be worthwhile to perform this block following the incubation of the primary antibody to reduce any potential damage to the epitope.
I hope these suggestions help to understand where the problems may be coming from. Have you tried using the antibody in Western blotting (an application which the anitbody has been used with before). What were the results of this?
We have several other antibodies which may provide better results than the ones you have observed so far, such as rabbit polyclonals ab18723 and ab77450. With both of these antibodies, if you were to have any problems in achieving good staining, you would be guaranteed by the Abpromise, more information of which can be found from the following link:
I hope this information has been of help. I look forward to recieving your reply.

Thank you for contacting us and reporting the difficulty you have found in using the anti-Doublecortin antibody (ab113435) in IHC.
As discussed over the phone, we have not ourselves tested this antibody in IHC and have had no reports of our customers having tried it either. It may therefore be that the antibody is not suitable for this application. However, I would be happy to try to advise you as to how the protocol may be optimised in order to obtain the best results. For this reason, I have attached the questionnaire we discussed over the phone to this email.
If you have managed to find out if the antibody your colleagues were using to stain Doublecortin was ab113435 that would be very interesting to know. And if you are able to share with me the lot number they used I can have a look into this as well.
I look forward to receiving your reply.

Thank you for contacting Abcam.

We have not yet tested ab113435 in IHC on brain sections, therefore we do not have a protocol that has been worked out for this antibody, I have however attached the Abcam general IHC protocol. Also as it has not been tested in this application, I am happy to offer you a testing discount for this antibody, you can find more information on this by following the link below:


I would recommend that you also look at ab18725, as this antibody has been shown to work in various IHC methods and in multiply species.

Please let me know if you would like to take advantage of our testing discount program or if there is anything else I can help you with.
