Target

  • Function

    Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles.
  • Tissue specificity

    Liver.
  • Sequence similarities

    Belongs to the GST superfamily. Alpha family.
    Contains 1 GST C-terminal domain.
    Contains 1 GST N-terminal domain.
  • Domain

    The C-terminal domain may form a component of the hydrophobic substrate-binding site, but in contrast appears not to be directly involved in GSH binding and is not absolutely essential for catalytic activity.
  • Cellular localization

    Cytoplasm.
  • Target information above from: UniProt accession P08263 The UniProt Consortium

    Answer

    Thank you for taking the time to complete our questionnaire and contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.
    The details you have kindly provided will enable us to investigate this case for you and this is also helpful in our records for monitoring of quality.
    Reviewing this case, I would like to offer some suggestions to help optimise the results from ab53940. I would also appreciate if you can confirm some further details:
    1) The lysis buffer seems unusual (we usually recommend RIPA buffer), but if it works for you it is fine. However, we strongly recommend adding freshly prepared protease inhibitors. Degradation of proteins can occur very quickly, leading to an unspecific banding pattern which might explain the results you observe. For details see our WB guide attached.
    2) We usually recommend 20-30 ug per lane, so the 30 ug you loaded should be absolutely fine to avoid overloading which might increase unspecific signals as well.
    3) When testing our antibodies, our lab uses 5% BSA as a blocking reagent, so I recommend switching to this instead of milk. For unknown reasons some antibodies give stronger, more specific signals on blots blocked with BSA instead of milk, so doing this may improve the results you are seeing, and reduce the non-specific bands. An example of the above is the western blot obtained with the Abcam GAPDH antibody ab9385 : https://www.abcam.com/gapdh-antibody-hrp-loading-control-ab9385.html#GAPDH-Primary-antibodies-ab9385-3.jpg (or use the following: www.abcam.com/ab9385). Also, it is then recommended to use the same blocking reagent also in the antibody dilution buffers (i.e. no mixing of milk/BSA).
    4) Have you performed a no primary control to see if the additional bands are caused by unspecific binding of the secondary antibody?
    I hope some of these suggestions will improve the results. If the antibody was purchased in the past 6 months you are covered by our Abpromise guarantee. Therefore if the suggestions do not improve the results I would be happy to offer a refund or replacement vial. Please do not hesitate to contact me should you have additional questions. Thank you for your cooperation.

    Question

    i purchased the GSTA-1 antibody from your company. recently, i run my western blot and i get a specific band at˜20-26kda. but at the same time i get multiple non specific bands which are more intense compared to the specific bands. i tried with increase with either the protein amount or antibody concentration, but yet it doesnt improve the result.can i noe is there any solution to solve this problem?? or any of your customer encounter this problem before and how they solve it? thank you for your help...thank you and have a nice day!

    Answer

    Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this Glutathione S Transferase alpha antibody.
    The quality of our products is important to us and I would like to reassure you that we investigate all customer complaints. We have received no complaints about this product so far and therefore I am concerned it is not working for you.
    Non specific bands can be caused by various factors, and I would like to investigate this particular case further for you, and also obtain more information for our quality records. In order to proceed with this, I have enclosed a questionnaire. I would appreciate if you could complete this. It will help you put the information we require together very easily.
    I would appreciate if you could also provide an image which would help us to assess the results.
    In the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.
    Thank you for your time and cooperation. We look forward to receiving the completed questionnaire.
