Use of gelatin/plasma coated flasks for isolating human peripheral blood monocytes

A simple and efficient technique to purify human peripheral blood monocytes is described. This technique is based on the fact that monocytes have high affinity for fibronectin immobilized on a gelatin coated surface. Cell preparations obtained by the method described are more than 90% monocytes. The phenotype of these adherent cells was characterized with monoclonal antibodies.
