Heparin and its fragments, namely, trisulfated disaccharide, pentasulfated tetrasaccharide, octasulfated hexasaccharide and an oligosaccharide (M.W. 6,300) prepared by enzymatic fragmentation and an oligosaccharide (M.W. 4,500) prepared by chemical fragmentation are potent inhibitors of skin
The sulfation at the 3-OH position of glucosamine is an important modification in forming structural domains for heparan sulfate to enable its biological functions. Seven 3-O-sulfotransferase isoforms in the human genome are involved in the biosynthesis of 3-O-sulfated heparan sulfate. As a rare
SR123781A, a synthetic hexadecasaccharide comprising an antithrombin (AT) binding domain, a thrombin binding domain, and a neutral methylated hexasaccharide sequence, was obtained from glucose through a convergent synthesis. SR123781A showed high affinity for human AT (Kd = 58 +/- 22 nM) and was a
Three homogeneous antibodies against the capsular polysaccharide of Type III pneumococci of similar specificities and affinities were purified from a single bleeding of an individual rabbit and fractionated by isoelectric focusing. A comparison of the circular dichroic spectra of the three
