Target

  • Relevance
    Beta galactosidase is coded by a gene (lac z) in the lac operon of Escherichia coli. It is a metalloenzyme that splits lactose into glucose and galactose. It hydrolyzes terminal, non-reducing beta-D-galactose residues in beta-D-galactosides. Activation by cations seems to be substrate dependent. K+, Na+, NH4+, Rb+, Cs+ and Mn++ all activate enzyme activity based upon the substrate used.

    Question

    Product code: 4761

    Inquiry: Dear customer service, I am really confused about this product. People are asking you if it could be suitable on human tissue sections and your answer is yes. Does it mean that this antibody cross reacts with human b-galactosidase? If so, does it also cross react with murine b-galactosidase? My understanding is that the immunogen is the E.coli form, therefore -unless the epitope is conserved between human and bacteria, it should not cross react. Many thanks for your reply

    Read More
    Answer

    Thank you for your inquiry.
    I can confirm that ab4761 will detect beta Galactosidase from E.coli origin.
    If beta Galactosidase is overexpressed (ectopically expressed) in human tissue than this antibody is suitable for this.
    We tested this antibody with beta Galactosidase that was expressed in HeLa cells.
    I hope this information is helpful and apologize for the confusion. Please feel free to contact me again if you have any further questions.

    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.
    I would like to reassure you that ab4761 is tested and covered by our 6 month guarantee for use in samples that overexpress beta Galactosidase and IHC. In the event that a product is not functioning in the applications cited on the product data sheet, we will be pleased to provide a credit note or free of charge replacement.
    Reviewing this case, I would like to offer some suggestions to help optimise the results from ab4761.
    1.) I recommend to use a permeabilization step since I assume that the beta Galactosidase will be overexpressed in the cytoplasm. 0.1% triton for 10 minutes only at RT.
    2.) The BSA in the primary antibody solution can be omitted.
    3.) I recommend to run a WB with the sample to confirm the expression of beta Galactosidase.
    4.) It might be worth to try without antigen retrieval.
    I would also appreciate if you can confirm some further details: 1.) Please give more details where the beta Galactosidase is overexpressed, what system was used and how the expression was tested.
    2.) Is the secondary antibody and the rest of the detection reagents working?
    I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details.

    Question

    Dear Sir or Madame,

    I am a graduate student at Scottish Centre of Regenerative Medicine.

    We are interested in unconjugated rabbit or rat anti-beta-galactosidase antibody (anti-LacZ Ab). We plan to use this Ab on mouse embryonic tissues:routinelyfor whole mount staining andoccasionallyfor cryo-sections. We have found several anti-LacZ Abs on your web-site, but they seems are not recommended for our particular application.

    Those are ab616 and ab4761. ab616 is not recommended for immunohistochemistry according to yourdescription. The only option left is ab4761, however it was tested with parafin sections and WB; and there are no images. I have heard (on "Origins of tissue stem cells" conference organized with Abcam, June 29, 2012) that in such circumstances we can buy the antibody with some discount. Could you advise, please.

    Sincerely,

    Read More

    Question

    Good afternoon

    I wonder if you can give me some info on the antibodies you have available.

    I want to demonstrate Beta Galactosidase in paraffin sections of human lung tissue.

    Do you have any antibody which would be suitable for this application

    Thanks for your help

    Read More
    Answer

    Thank you for contacting us.

    We have several antibodies against beta galactosidase, two of which have been validated for IHC staining of paraffin embedded sections. You may want to consider chicken polyclonal ab9361 or rabbit polyclonal ab4761. These have not been validated in human tissue specifically but should be compatible in detecting the Beta galactosidase protein.

    I hope this information has been of help. If you require any further information please do not hesitate to contact us again.
