I have used this service for several years now with no complaints at all so far! They know their stuff very well!! Very helpful staff who do what they say without any question asked or problems solved. Would highly recommend them if you need help setting up an elispot system. ! Nothing yet but will update once i get feedback from my client that it's working great. !! We use Elispot systems daily as part of normal business operation here which includes tracking vaccine trials data (both human/animal) using multiple antigens simultaneously - hence we needed something more than just software solution available out thertat daylily!! This was done by ctl contract labscannerandanalysisthroughouttheyears till today! Great job guys. . !! If anyone has questions regarding product selection please feel free t contact us via email info@ctldevicesolutionsllc com Thank You.
