Application Abreviews Notes
IP Use at an assay dependent concentration.

WB Use a concentration of 1 µg/ml. Detects a band of approximately 20 kDa (predicted molecular weight: 20 kDa).


  • Function
    May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity (By similarity). Involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Its binding to DPP4 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. Recruits CTNNB1 to caveolar membranes and may regulate CTNNB1-mediated signaling through the Wnt pathway.
  • Tissue specificity
    Expressed in muscle and lung, less so in liver, brain and kidney.
  • Involvement in disease
    Defects in CAV1 are the cause of congenital generalized lipodystrophy type 3 (CGL3) [MIM:612526]; also called Berardinelli-Seip congenital lipodystrophy type 3 (BSCL3). Congenital generalized lipodystrophies are autosomal recessive disorders characterized by a near absence of adipose tissue, extreme insulin resistance, hypertriglyceridemia, hepatic steatosis and early onset of diabetes.
  • Sequence similarities
    Belongs to the caveolin family.
  • Post-translational
    The initiator methionine for isoform Beta is removed during or just after translation. The new N-terminal amino acid is then N-acetylated.
  • Cellular localization
    Golgi apparatus membrane. Cell membrane. Membrane > caveola. Membrane raft. Colocalized with DPP4 in membrane rafts. Potential hairpin-like structure in the membrane. Membrane protein of caveolae.

Thank you for your reply.

Having talked to my colleagues we can go ahead and replace those antibodies for you; however before we do we would like to understand why there was such a delay in the package being delivered to you, so it does not happen again.

As we talked about on the telephone yesterday, according to FedEx records they tried to deliver it twice on Monday (24th Sep) & twice on Tuesday (25th), before successfully being able to deliver it on Wednesday (26th). The reason for the failed delivery attempts was that there was nobody there to receive it. Therefore I wanted to check the shipping address with you and see if it needs to go to a different location to guarantee that someone will be there Mon-Fri, 9am-5pm. The shipping address we have is:

Please could you confirm this is the correct address where the package will be sent and also please let me know if there are any days that the package should not be delivered and I will update our notes.

I look forward to your reply.

Thank you for calling Abcam earlier today.

I am sorry that ab18199 was not working for you. I am going to talk to my colleagues about the best way to proceed win this matter.

I just had a few follow up questions:

1 - Did you try all 3 vials of the antibody? If so, did they all fail to give a signal?

2 - Could you please let me know primary antibody concentrations you have tried and also the incubation times?

I look forward to your reply and helping to resolve this issue.

The discount would be to the value of 1 free primary antibody.

If you are interested in this offer, please follow these steps:

1. Reply to this e-mail to let me know that you would like to proceed and test an Abcam antibody in Chicken. I will then send a discount code. This code must be issued before purchasing the antibody you would like to test, so please wait for my reply before ordering.

2. Purchasethe antibodyeither by phone, fax, or online (www.abcam.com).

3. Test it in in Chicken.

4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!). To find out how to submit an Abreview, please visit: https://www.abcam.com/abreviews.

5. After the review is submitted to us, the discount code becomes active. Simply place your new order by phone, fax, or on the web and mention the discount code. The discount can be redeemed for anyprimary antibodyordered and the discount code is valid for 4 months after issue.

We are always pleased to obtain feedback about our products and any information is greatly appreciated! Even ifthe tested antibodyturns out to be unsuitable for Chicken, you will still receive the discount on your next purchase after your Abreview has been submitted.

The Terms and Conditions of this offer can be found at: www.abcam.com/collaborationdiscount.

If you are interested in this offer, please inform us which application you would like the antibody in so I can narrow down the choice of the antibodies.

I am going to contact the lab where the anti-eIF2 alpha(ab115822) is produced in order to ask for the immunogen sequence or region.

Thank you for contacting us.

Here is the information I have received from our lab:

We haven’t tested this ab for crossreactivity with caveolin 2 and caveolin 3 but I’ve done a quick blast of our immunogen sequence against Mouse and it looks to be specific to caveolin 1.

If it does turn out that the KO mice are fine and it is our antibody, it would be wonderful if youcould let us know. In that case, please provide us with the experimental details and results, so that I can pass it on to our lab.

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