What they say about us

Dealing with Citeq is more of an academic collaboration than a supplier customer relationship. They are are always happy to open and frank discussions  and willingly answer questions on preparation methodology and extract composition. I cannot recommend Citeq highly enough to researchers in the field of allergy and inflammation.
