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

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 52 kDa (predicted molecular weight: 52 kDa).

  • Application notes

    • Target

    • Function

      The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is adenylate cyclase inhibition.

    • Involvement in disease

      Genetic variations in CHRM2 can influence susceptibility to major depressive disorder (MDD) [MIM:608516]. MDD is one of the most common psychiatric disorders. MDD is a complex trait characterized by one or more major depressive episodes without a history of manic, mixed, or hypomanic episodes. A major depressive episode is characterized by at least 2 weeks during which there is a new onset or clear worsening of either depressed mood or loss of interest or pleasure in nearly all activities. Four additional symptoms must also be present including changes in appetite, weight, sleep, and psychomotor activity; decreased energy; feelings of worthlessness or guilt; difficulty thinking, concentrating, or making decisions; or recurrent thoughts of death or suicidal ideation, plans, or attempts. The episode must be accompanied by distress or impairment in social, occupational, or other important areas of functioning.

    Question

    thank you for the offer to replace the above mentioned antibody with another one. As I did not find any suitable M2R antibody in your catalog, I would like to exchange this one to a completely different one. Is this OK?

    What I would like to have is the antibody ab32087 (Anti MCL-1 antibody Y37)

    How should I proceed with this, do I need to order it or will you be taking care of the shipping just like this?

    Thanks a lot!

    1) Abcam product code ab 109226
    2) Abcam order reference number or product batch number GR50911
    3) Description of the problem Antibody: does not show expected membrane localization of muscarinic receptor, instead the staining resembles the pattern of microtubule and colocalizes with tubulin!
    4) Sample preparation:Species Homo SapiensType of sample: Cells in culture (HeLa cells)
    Sample preparation Cells were grown on coverslips with serum-containing mediumPositive control Negative control 5) Fixation step Yes If yes: Fixative agent and concentration Following conditions were tested for this antibody: Fixation in 100% methanol and in 4% paraformaldehyde.
    Fixation time 10 min Fixation temperature Fixation with methanol at -20°C; fixation with paraformaldehyde at room temperature 6) Antigen retrieval method 7) Permeabilization method:
    Did you do a permeabilization step (details please) or add permeabilizing agent in any dilution buffers? Permeabilizing agent and concentration: Cells fixed in 4% paraformaldehyde were permeabilized with 50 µg/ml digitonin. For MeOH, no permeabilization necessary.
    8) Blocking agent (eg BSA, serum…): Concentration 1% BSA in PBS Blocking time 10 min Blocking temperature room temperature 9) Endogenous peroxidases blocked? not relevant Endogenous biotins blocked? not relevant 10) Primary antibody (If more than one was used, describe in “additional notes”) : Concentration or dilution 1:100 Diluent buffer 1% BSA in PBS Incubation time 60 min
    11) Secondary antibody: Species: Donkey Reacts against: rabbit Concentration or dilution 1:300
    Diluent buffer 1% BSA in PBS Incubation time 60 min Fluorochrome Alexa-488, Cy3
    12) Washing after primary and secondary antibodies: Buffer PBS Number of washes 3 times in PBS and one quick wash in water 13) Detection method Immunofluorescence
    14) How many times have you run this staining? Twice Do you obtain the same results every time? Yes What steps have you altered to try and optimize the use of this antibody?

    Question

    ich schreibe das auf Englisch, für den Fall, dass Sie es weiterschicken müssen

    We have recently ordered an antibody Ab109226 against muscarinic acetylcholine receptor 2 (Lot GR50911). This antibody has been declared to work in Western blot and immunocytochemistry. In WB, we got the expected band around 50 kDa plus some higher MW bands. However, we were not able to see any difference between nontransfected cells and those transfected with an M2R plasmid.

    We also tested this Ab in immunofluorescence, and the staining pattern does not correspond to the expected membrane protein pattern. Instead, we see what clearly looks like a tubulin cytoskeleton! Thus, we performed double staining with the M2R antibody (see enclosed picture M2R_HeLa_MeOH) and alpha-tubulin (Tubulin_HeLa_MeOH), and the stainings indeed overlap to a very large degree! In Addition, if you look at the picture M2R in mitotic cell, you will see that in a dividing cell, the staining is concentrated in the midbody region where you expect to see the tubulin cytoskeleton. This would not be the expected location of the M2R! Fixation with PFA produces very similar results, so this is not the cause…

    I was wondering if you have any idea what is wrong with this antibody? We purchased it since we were very happy to see that there is an antibody that works for several methods. Could it be that this specific lot contains a wrong antibody (labeled with wrong number?) instead of the M2R ab, since the staining that you have in your website indeed looks more like M2R. For WB, you cannot tell the difference since both proteins are close to 50 kDa.

    I would deeply appreciate if you could solve this mystery since we dearly need a functional antibody for this protein. If this turns out to be a lot-specific problem, we would be happy to receive a replacement of a batch that works! Otherwise, I would like to receive our money back since this Ab definitely does not recognize what it is supposed to.

    Thanks a lot!

    Answer

    Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

    I can confirm that, no other complaint was received for this antibody so the problem could be either with antibody or the protocol. We also do not mislabel products so the antibody you have received is indeed correct product.

    Multiple bands or high background problem is quite common with antibodies which can be overcome with troubleshooting so I am very much interested in checking the protocol you have been using. I have attached WB and IHC/ICC questionnaire for getting the information we need to make any decision regarding the quality of lot GR50911.

    Please fill these document and send these to me as per your earliest convenience.

    I will look forward to hearing from you soon.

    Blocking peptide for ab2805

    Read More
    Answer

    Thank you for contacting us.

    Unfortunately we do not have blocking peptides for any of the antibody ab2805, ab90805 and ab109226. I apologize for the inconvenience this may have caused.

    I can however recommend trying the following protocol steps as alternative˜
    - use negative control cells or tissue that does not express this protein. The human protein Atlas database can help in finding this.
    - Use no primary control sections
    - Use isotype control antibody

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