Anti-Aggrecan 抗体 [6-B-4] (ab3778)

Sorry but we don't have a standard ELISA procedure for use with this antibody. However I would recommend using an indirect ELISA approach. This is outlined here https://www.abcam.com/index.html?pageconfig=resource&rid=11389

Thank you for contacting us.

Unfortunately the indicated primary antibodies have not been tested with Flow Cytometry, and therefore are not covered by our Abpromise guarantee.

I would instead recommend using a different antibody against Collagen II that has been tested in this application:

I am afraid none of the antibodies against Aggrecan in our catalogue have been tested in Flow Cytometry, but if you wish to test them and share your results with us (through the Abreview system) we will be happy to offer a discount code for a future purchase.

If you would like to participate in the Abreview system and test ab3778 with Flow Cytometry, please let me know before placing the order so I can raise the discount code for you.

Ab97022 is a suitable secondary for recognising Mouse primaries with Flow Cytometry. The only recommendation for this particular antibody is using it at dilutions 1/50-1/200. For general Flow Cytometry protocols I would encourage you to have a look at our Website’s protocols which may be very helpful (open the scroll down menu under the Flow Cytometry / FACS tab to have access to all the FC protocols).

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information

Vielen Dank für Ihren Anruf.



Leider habe ich eine schlechte Nachricht für Sie: Aggrecan hat insgesamt eine Übereinstimmung von 19%, es gibt eine Region zwischen AS 800-850 des menschlichen Proteins, welches eine hohe Übereinstimmung mit dem Ziegen Protein hat, nur haben wir leider keinen passenden Antikörper.

Versican und SOX5 weisen leider gar keine Übereinstimmung mit dem Ziegenprotein auf.

Da alle unsere Aggrecan,Versican und SOX5Antikörper gegen das humane Protein entwickelt worden sind, kannich Ihnen leider keinen Vorschlag machen.

Ich hoffe, dies hilft Ihnen trotzdem weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Thank you for your inquiry.


We have quite a few references for this antibody to be used in ICC/IF and IHC-Fr/IHC-P. You can find them listed here and they are linked to the PubMed IDs.

You may also be interested in reading our customer reviews, called Abreviews, which include their protocol and images.

Gracias por contactarnos.

Varios marcadores pueden usarse para la detección de condrocitos mediante immunohistoquímica. Solo algunos de ellos se han testado en especie canina, el resto me temo que no se han testado, por lo que se desconoce su funcionamiento en ellas.

Le indico algunas posibilidades con los números de catálogo de Abcam:

Collagen II: podría usarse ab300 o ab34712. Ninguno de ellos se ha testado en perro. Si está interesado en usarlo en esta especie, quizás le interese participar en el sistema Abreviews de evaluación de anticuerpos, por el cual les ofrecemos un anticuerpo completamente gratuito al mandarnos los resultados de testar el anticuerpo en la nueva especie. Si le interesa, por favor, comuníquemelo antes de realizar el pedido.

Para saber más sobre el sistema Abreviews: https://www.abcam.com/abreviews

Aggrecan: ab3778. Tampoco testado en perro, pero susceptible de evaluar su aplicación.

CD29: ab30388. En este caso tampoco hay datos de su uso en especie canina, tendría que evaluarlo usted misma.

CD44: ab19622 y ab119863. Ninguno de ellos se ha testado en perro, sin embargo, debido al elevado porcentaje de homología con dicha especie, es probable que reaccione. Por ello, si le interesa comprobarlo, puede igualmente usarlo y enviarnos los resultados, beneficiándose de una futura compra totalmente gratuita.

SOX9: ab26414 y ab71762. En este caso, ambos anticuerpos se han usado y caracterizado en especie canina, por lo que están cubiertos por la garantía Abpromise.

Espero que esta información le sea de utilidad. Si necesita que le enviemos una proforma de alguno o varios de los anticuerpos, si necesita más información de alguno de ellos, o si quiere saber más acerca del sistema Abreview, por favor, no dude en volvernos a contactar.

Thank you for contacting us.

For the aggrecan antibody ab3778, I recommend the following two papers, if they are avalable to you, the first of which describes production of this clone and its use for IHC. We do not have access to the journal.

Caterson B et al. Mechanisms involved in cartilage proteoglycan catabolism. Matrix Biol 19:333-44 (2000). PubMed: 10963994

Little CB et al. Matrix metalloproteinases are involved in C-terminal and interglobular domain processing of cartilage aggrecan in late stage cartilage degradation. Matrix Biol 21:271-88 (2002). PubMed: 12009333

Please also note the review of ab3778 submitted by a customer on March 21, 2007, who included this note:

"We tried multiple retreival methods and found that pronase and hyaluronidase will work. The best results were with hyaluronidase".

(I suggest trying the hyaluronidase solution that is mentioned below for use with the collagen II antibody: 2mg/ml hyaluronidase in TBS for 2 hours at 37C).

For the collagen II antibody, an Abcam customer submitted an Abreview with the following protocol for IHC of formalin-fixed paraffin-embedded human cartilage tissue:

Antigen retrieval step: Enzymatic - Buffer/Enzyme Used: 2mg/ml hyaluronidase with 0.125U/ml chondroitinase in TBS for 2hrs 37C.

Blocking step: Normal goat serum in 1% BSA as blocking agent for 30 mins · Concentration: 20 % Temperature: 21°C.

Dilution of antibody: 1/50

Incubation time: 18 hours

Temperature: 4°C

Diluent: Blocking solution.

Thank you very much for your email. Indeed, I have to agree with you that there is a problem. I would like to apologize for this and would like to reassure you that we will investigate this further and take the appropriate actions. The mouse reactivity has been added due to a customer feedback. Doing however the alignment of the immunogen with the mouse sequence, there is little overlap and it looks therefore rather tricky to get a specific staining on mouse cells. ** *.:*:***: http://www.ebi.ac.uk/Tools/services/web_clustalw2/toolresult.ebi?tool=clustalw2&jobId=clustalw2-I20111207-093227-0400-33224393-pg I will remove the mouse reactivity and replace this antibody for you with another antibody of your choice. Please do provide me therefore with the order details, such as the order number or the order date and name of the person placing the order. Unfortunately, we do have currently however no anti aggrecan antibody tested in your application and species. If you would like nevertheless to use one of our other anti aggrecan antibodies, I would be pleased to make predictions for the suitability. I apologize again for this error and am looking forward to hear back from you.

Thank you for your enquiry. Unfortunately, we do not have a Certificate of Analysis for this product. If there is anything else that I can help you with, please do not hesitate to contact me.
