Hello, Has anyone had experience with using the anti-S polyclonal reagent manufactured by Hemo bioscience. I am at a smaller hospital and looking to lower my reagent costs. Hemo bioscience offers polyclonal antisera for S,s,K,k, M, and Fya . The price for anti-S is much lower then Ortho or Immucor. I would be interested in any feedback from folks who are now using this anti-S reagent. Thanks, David Thomas
