Web13 jan. 2006 · The biological roles of heparin (HP) and heparan sulfate (HS) are mediated mainly through their interaction with proteins. In the present work, we provide a rapid method for screening HP/HS-protein interactions providing structural data on the key sulfo groups that participate in the binding. Heparin was discovered by Jay McLean and William Henry Howell in 1916, although it did not enter clinical trials until 1935. It was originally isolated from dog liver cells, hence its name (ἧπαρ hepar is Greek for 'liver'; hepar + -in). McLean was a second-year medical student at Johns Hopkins University, and was working under the guidance of Howell investigating pro-coagulant preparations, when he isolated a fat-soluble …
