Thank you for contacting us.

The WB image was obtained under the following conditions:

The gel was 8% SDS-PAGE. About 30 ug total protein was loaded on each lane.

As for mouse data, I found out that they have not yet been tested, but theimmunogen sequence has very high identity with mouse. I have changed the datasheet to reflect this information. I apologize that it did contain incorrect information.

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

Thank you for contacting us.

I have contacted the lab for the information you had requested.

In regards to the testing, I have checked with our BD department. Unfortunately, in this case we would not offercollaborator testing, since the antibody has been tested in human samples in WB and would beguaranteed. You are always welcome to submit anAbreview with your findings.

We guarantee all our products for tested species and applications as listed on the datasheet. The guarantee is valid for 6 months after a purchase. For more details about our Abpromise guarantee please check this link: https://www.abcam.com/abpromise.

I will be in touch when I hear back from the lab. Thank you for your patience.

In the meantime,please do not hesitate to contact us if you need any more advice or information.
