Mikel, I'm not sure how you are searching, but there should be Very Many out there. A google search of "e. coli detection antibodies" gave many results. Top one was www.lsbio.com with 36. Good luck!

@ Jackson: I did find many antibodies for E. coli but they were not specific for membrane proteins, which is crucial for my goal. I will try this engine you suggest me, thanks.

Hi Mikel,

I am having the same problem and was wondering if you find an antibody against membrane E-coli proteins?

Thanks.

Hi Ionel. I did obtain some anti-TolA and anti-TolQ antibodies from a collaborator eventually, I found no commercial ones though ...
