  • Description
    Rabbit polyclonal to Calcitonin receptor/CT-R
  • Host species
  • Specificity

    ab11042 recognises the calcitonin receptor/CT-R in human, mouse and rat. The calcitonin receptor/CT-R is a seven transmembrane domain cell surface protein which is coupled to G protein messenger systems. This antibody recognises an epitope within the cytoplasmic domain that is common to both C1a and C1b rat isoforms.

Our Abpromise guarantee covers the use of ab11042 in the following tested applications.

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

Application Abreviews Notes
IHC-Fr 1/10 - 1/50.
IHC-FoFr Use at an assay dependent concentration.
IHC-P 1/10 - 1/50. We recommend the use of 4% paraformaldehyde fixation, rather than formalin fixation. A sensitive detection system is also recommended. e.g. A catalysed signal amplification system. This product does not require protein digestion pre-treatment This product does not require antigen retrieval using heat treatment prior to staining of paraffin embedded sections.
WB Use at an assay dependent concentration. Predicted molecular weight: 56.9 kDa.
ELISA 1/10000.

Tissue samples were fixed by perfusion with paraformaldehyde, permeablized with 0.3% Triton-X, blocked with 5% serum for 45 minutes at 22°C. The sample was incubated with primary antibody (1/500) at 4°C for 18 hours. An Alexa Fluor® 488-conjugated Donkey anti-rabbit polyclonal (1/500) was used as the secondary antibody

We have only two antibodies anti-human calcitonin receptor guaranteed to work in WB in our catalogue: ab103422 and ab11042.

Both of these should recognise all three human isoforms since there is a large sequence homology between all isoforms. However, we have not directly tested this and therefore cannot guarantee this.

Vielen Dank für Ihre Email.

Leider haben Sie Recht, was das austesten mit der technovit 9100neu angeht, und auch versenden wir keine Proben, da wir bei über 90.000Produkten gar nicht die logistischen Möglichkeiten haben, neben unserer eigentlichen Produktpallette Teströhrchen zu lagern.

Wir bieten auch generell keine Institutsrabatte, aber wir möchten Sie jedoch einladen, unser Abreview-System zu verwenden. Dafür belohnen wir Sie mit unseren Loyalitätspunkten, die Sie in Rabatte umwandeln koennen.

Nachdem ich Sie bisher immer enttäuschen musste, möchte ich Ihnen aber wenigsten etwas den Freitag versüßen: Ich habe Ihnen einen Gutschein über einen kostenlosen Versandt ausgestellt, den Sie bei der Bestellung dieses Antikörpers nutzen können.

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

Thank you for your enquiry. Ab11042 was raised against a synthetic peptide with the following sequence: KGLPIYICHQEPRNPPVSNN-NH2. I have updated the datasheet with this information for future reference. I hope this information helps. Please do not hesitate to contact us if you need anything further.

I have just received the following information from the source of ab11042: "The cross-reactivity of this antibody with the human calcitonin receptor has been demonstrated by the antibody originator using human foetal kidney (pathology specimens), fixed in formalin. The antibody was successfully used at dilutions as low as 1:500 but a catalysed signal amplification (CSA) system was required (also called tyramide signal amplification). Antigen retrieval was not required, indeed the originator did not have much success when employing such techniques. Based on this information, we would suggest that the customer employs this kind of signal amplification step on her renal biopsies. The originator reports staining of osteoclasts (rodent) using the polyclonal antibody ab11042 both in paraffin sections and from cell culture. To our knowledge, human osteoclasts have not been specifically tested. This antibody has recently been tested on COS7 cells transfected with rat calcitonin receptor and human calcitonin receptor. Not surprisingly, this anti-rat antibody reacts best with the rat calcitonin receptor, and less so with human calcitonin receptor (antibody reactivity and working conditions may vary between species). These studies were conducted on fixed permeabilised COS7 cells, using immunofluorescence. We would recommend the use of the mouse anti-human calcitonin receptor antibody ab11040. Again this antibody has been used successfully on human foetal kidney sections (formalin-fixed, paraffin) with signal amplification may improve the staining. Perhaps your customer would consider testing this antibody in their system, as this would be more suitable for their needs." I hope this information will be of some assistance to you.

I'm sorry to hear you are having problem with ab11042. I would like to suggest trying the immunohistochemistry steps without antigen retrieval prior to staining of paraffin embedded sections. I would also recommend using triton (0.3%v/v)in PBS in all buffers used to block/dilute antibodies/dilute streptavidin. Please let me know if this helps and do not hesitate to contact us for further advice,

Thank you for your enquiry. This antibody is specific for the calcitonin receptor. This receptor is expressed by osteoclasts but expression has also been reported in the kidney, central and peripheral nervous systems. We hope that this information is of assistance.
