Thank you very much for the reply.

It is clear from the images provided that the customer has observed some background with the secondary antibody. In order to reduce this, I would advise reducing the concentration which is currently being used. We would recommend initially trying 1/1000-1/5000 for the experiment the customer is currently trying.

I hope this information has been of help. If the customer continues to have problems following this advice please do let us know and we will endeavor to help further.

I hope you ave a nice weekend.
