    • Form

      5T4 is a 72 kDa transmembrane glycoprotein that exhibits restricted expression in human and mouse adult tissues, is upregulated on many carcinomas and tumour expression correlates with poorer clinical outcome in ovarian, gastric and colorectal cancers. mES cells lack cell surface expression of the 5T4 antigen, and both protein and mRNA are rapidly upregulated following induction of differentiation. This proteins expression correlates with downregulation of OCT-4 and Tra-1–60 (Ward et al., 2006).

    Answer



    When an antibody is noted as 'unsuitable', it has been tested in that application. It may be that optimized conditions or samples were not used during this QC so I am happy to see that you have had success with your IHC. Thanks very much for your protocol advice. I will pass this on!

    Answer

    Thank you for contacting us. Please find below the notes on the image with pervanadate.


    Prepare 500mM stock Sodium Orthovanadate in PBS. To make
    100X Pervanadate right before experiment, add 400ul 500mM Sodium Orthovanadate to 1560ul H2O and then 40ul H2O2(Fisher #H325-100), vortex and incubate at RT for 5-10min.

    Cells are serum-starved for overnight, and then treated with freshly made Pervanadate for 20min at 37 degrees C.


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