Our Abpromise guarantee covers the use of ab12081 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
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 116 kDa.


  • 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.

    Thank you for confirming these details and for your cooperation. The details provided enable us to closely monitor the quality of our products. I am sorry this product did not with the full amount as stated on the datasheet and for the inconvenience this has caused. I have issued a free of charge replacement for a full vial of ab12081 with the order number xxxxx. As to the cloudy appearance I would recommend spinning the antibody down for a few minutes and drawing the antibody from the top. You should not see any reduction in affinity. To check the status of the order please contact our Customer Service team and reference this number. Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know. I wish you the best of luck with your research.

    Thank you for your phone call.

    As we discussed, I recommend using aqueous mounting media for fluorescent detection, such as ab104139. These media are often specially formulated to preserve the fluorescence and simultaneously counterstain with DAPI. I hope this heps, if not, please let me know and I will be happy to assist you further.
