Question (41084) | Anti-smooth muscle Myosin heavy chain 11 antibody [1G12] (ab683)

Go to datasheet (ab683)


Please see below the response from a customer;

We have tried this antibody with human smooth muscle cells and it did not work.

We would appreciate Abcam supplying us with the replacement antibody ab53219. This antibody has not been tested with human cells but we are prepared to try it with our cells and report back the activity.


Thank you for contacting us.

Yes, I'd be happy to replace ab683 with ab53219 (which is also an Anti-smooth muscle Myosin heavy chain 11 antibody). Since this antibody has not been tested in human samples, we would not be able to guarantee it for human samples. Thus, the Abpromise guarantee would not apply. However, I can issue a testing discount code for the customer. For more details on this offer, please see below.

For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:
The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody at the full price (100%) of the antibody you have tested. The terms and conditions applicable to this offer can be found here:

Please let me know if the customer would like to receive the testing discount code.

I look forward to hear back from you and assist you further.
