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

    Inquiry: Hello. I just received a shipment of ab12081 Goat anti LacZ lot. As I was aliquoting the antibody for long term storage at -20 I only was able to retrieve 70uL of antibody but there should be 100ul in the vial. The vial was centrifuged before opening and the inside of the lid was checked for residual liquid.. none was found. Also the antibody solution had a noticeable cloudy white appearance that I have not noticed in other lots of this product before. Thanks in advance for your assistance. Cheers Steve

    Answer

    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.

    My Fluorescent signal is weak using xylene based mounting media.

    Answer

    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.

    Question

    Thanks for your help on this matter. Much appreciated.  I have attached an email showing the purchase of this anti lacZ antibody from March 24 2011... just short of 6 months.  The current lot # we are using is 134764. Would you happen to know if there is a different lot to try?   Also I was hoping to just place the order through Cedarlane again if that is OK with you?  Thanks again

    Answer

    Thank you for your email. Unfortunately we only have the same lot in stock, would you like a replacement from the same lot or an alternative product? We will be able to organise the replacement with Cedarlane. Looking forward to your reply.
