I have a question aboutab8978.
I found that it is mouse monoclonal and was tested in mouse sample on the data sheet.
I thinks that it is theoretically impossible because this antibody have to use anti-mouse IgGas secondary antibody.
So it can show high backgroundby non-specific bindingto endogenous mouse IgG especially in case ofIHC.
I would like to know how it is possible.
Please inform me.

Thank you for contacting us.
Indeed, a mouse-on mouse staining can be quite tricky; however, it is not impossible. The background will depend on the fixation method ( perfusion fixed tissue vs. normally fixed tissue), on the tissue itself ( eg. kidneys vs. bone) and the experimental settings.
One way to make sure to decrease or to completelyerase the background is to block the endogenous mouse IgG with a non- conjugated secondary antibody before you incubate with your target antibody. I would suggest to use a Fab or F(ab)2 fragment antibody in this case as they will bound in a higher density than whole IgG antibodies.
