• Product name
    Anti-Chondroitin Sulfate antibody [CS-56]
  • Description
    Mouse monoclonal [CS-56] to Chondroitin Sulfate

  • General notes

    This product was changed from ascites to tissue culture supernatant on 25th October 2016. The following lot(s) is/are from ascites and is still in stock as of 25th October 2016 - GR288674, GR272407. Lot numbers higher than GR288674, GR272407 will be from tissue culture supernatant. Please note that the dilutions may need to be adjusted accordingly

    Storage in frost-free freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

    Many cellular activities depend on the interaction of cells with the surrounding extracellular matrix (ECM). Most cells, in intact tissue and in culture, are attached to an ECM. Epithelial cells are associated with the basement membrane; fibroblastic cells are usually embedded in a pericellular mesh of fibrils, and tissue culture cells usually grow on a substrate which is covered by various ECM components. Studies have indicated that the matrix or its various isolated components provide not only adhesive surfaces for cells to grow on but also have effects on the rate of cell growth, mobility, morphogenesis and differentiation. Within the ECM several glycoproteins and proteoglycans have been identified. It has been proposed that the different constituents interact with each other in a rather complex fashion. The poor antigenicity of proteoglycans especially their glycoaminoglycan (GAG) moieties make it difficult to localize these molecules in tissue and cell culture. Monoclonal Anti-Chondroitin Sulfate can be used to study chondroitin sulfate proteoglycan (CSPG) distribution and its relationships to specific cell-substrate contacts.



Our Abpromise guarantee covers the use of ab11570 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Vielen Dank für Ihren Anruf und für Ihr Interesse an unseren Produkten.

Ich freue mich Ihnen bestätigen zu können, dass ab11570 (Anti-Chondroitin Sulfate antibody [CS-56]) für Glykosaminoglykan (GAG) ist, unabhängig von der Spezies. Deshalb kann ich Ihnen diesen Antikörper empfehlen.

Unserem Wissen nach wurde ab77261 (Anti-Robo3 antibody) bisher noch nicht in Zebrafisch und IHC getestet.

Die Wahrscheinlichkeit, dass ab77261 in Zebrafisch funktioniert ist groß, da das Immunogen eine 91% Homologie aufweist.

ab77261 ist auch noch nicht für IHC getestet. Es sieht jedoch vielversprechend aus, da er für ELISA geeignet ist.

Falls Sie dies selbst testen möchten, kann ich Ihnen zurzeit 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 ab77261 abdecken, und gegen eine erneute Bestellung weiterer Produkte von uns verrechnet werden.

Um von diesem Angebot profitieren zu können, folgen Sie bitte diesen Schritten:

1.) Bestätigen Sie mir bitte, dass Sie ab77261 in IHC und/oder Zebrafisch 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 IHC und/oder Zebrafisch.

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:

6.) Der Rabattcode ist nach dem Abschicken des Abreviews aktiv, und Sie können weitere Produkte zu dem gleichen Preis wie ab77261 bei uns bestellen (halten Sie bei der Bestellung bitte den Rabattcode). Bitte beachten Sie, dass der Rabattcode innerhalb von 4 Monaten nach Ausstellung eingelöst werden muss.

Unfortunately we have not tested this product with digested chondroitin sulphate and so it is difficult to predict the outcome. GAGs alone are poorly antigenic and so the antibody may not interact with the D-glucuronic acid and N-acetyl-D-galactosamine from the chondroitinase reaction. We have not carried out epitope mapping for this antibody and so again we cannot say for certain whether product ab11570 will bind the proteoglycan core.

I'm sorry I could not provide more definitive information. Please do not hesitate to contact us if you require any further assistance.

Thank you for contacting us yesterday in regards to the Anti-Chondroitin Sulfate antibody [CS-56] (ab11570).

I have had a look into which tissues may serve as positive controls with the antibody. As the Chondroitin sulfate is a major component of the extracellular matrix I would expect most tissues to show positive staining. I have not been able to find any good references referring to the distribution of the target. As discussed over the phone, we have had reports of brain tissue being used:


I have also found reference to CS being abundant in fetal liver tissue with lower levels in adult liver tissue:

Gressner AM, Vasel A. Developmental changes of proteoglycan synthesis in rat liver and isolated hepatocytes. Mech Ageing Dev 1985; 31: 307-327

As there are several different chondroitin sulfate proteoglycans such as aggrecan, verican and CD44 it is difficult to determine the exact expression profile but I would expect both the muscle, skinand bone tissue you have access to show some positive staining as indicated from the following references:




I hope this information has been of some help. If you have any further questions, please do not hesitate to ask.

Thank you for your enquiry.

The 1.7mg/ml concentration is the antibody concentration which was determined by

Radial immunodiffusion (RID) method. For your information, the ascites concentration with other proteins included is actually 38mg/ml.

I hope this information will be helpful.

Thank you for contacting us.
Please be advised that ab11570 is not a Chondroitin protein that will be degraded by chondroitinase ABC enzyme. It is an IgM antibody.
I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your reply.

I can confirm that Anti-Chondroitin Sulfate antibody [CS-56], (ab11570) has been raised against the chicken protein. I am sorry this antibody has been sources externally, and regrettably we are not able to obtain the chicken sequence in order to align this with the sheep. The sheep sequence also appears to be unavailable.

For antigen retrieval,there has been an Abreview submitted by another customer who has used a commercially available antigen retrieval solution(Trilogy). I can recommend that antigen retrieval will often require some optimization.You may like to consider trying citrate bufferretrieval pH 6with several time points (3, 5, 10 and 20 minutes) to start with.

We do sell some pre prepared antigen retreival solutions:

I am sincerely sorry we have no more information regardingpotential crossreactivity with sheep again on this occasion. If you have any further questions, please do not hesitaet to contact us.

Thank you for contacting us. We need more information on the use of ab11570 and ab8610 in alphaLISA. Could you please answer the following questions? - Are you going to use these antibodies together or in combination with other antibodies? - Are you planning to conjugate these antibodies with different acceptor r donor molecules? - Are you planning to use these antibodies with different conjugated antibodies? e.g acceptor or donor molecule conjugated antibodies. - These antibodies are not tested together in Sandwich ELISA so how you are planning to proceed with the procedure? I am looking forward to hearing from you soon.
