Analysis of E. coli K5 capsular polysaccharide heparosan.
Heparosan is the key precursor for the preparation of bioengineered heparin, a potential replacement for porcine intestinal heparin, an important anticoagulant drug. The molecular weight (MW) distribution of heparosan produced by the fermentation of E. coli K5 was investigated. Large-slab isocratic and mini-slab gradient polyacrylamide gel electrophoresis (PAGE) were used to analyze the MW and ...

متن کاملR(C6, K5) = 21andR(C7, K5) = 25
R(C4, K4) = 10 (see [2]) R(C4, K5) = 14 (see [3]) R(C5, K4) = 13, R(C5, K5) = 17 (see [5, 6]) R(Cn, K3) = 2n − 1 (n > 3) (see [4, 7]). In [10], we proved that R(Cn, K4) = 3(n − 1) + 1 (n ≥ 4). In this paper, we will prove that R(Cn, K5) = 4(n − 1)+ 1 (n = 6, 7). The following notations will be used in this paper. If G is a graph, the vertex set (resp. edge set) of G is denoted by V (G) (resp. E...
متن کاملThe Ramsey Number r(K5-P3,K5)
For two given graphs G1 and G2, the Ramsey number r(G1, G2) is the smallest integer n such that for any graph G of order n, either G contains G1 or the complement of G contains G2. Let Km denote a complete graph of order m and Kn −P3 a complete graph of order n without two incident edges. In this paper, we prove that r(K5 − P3,K5) = 25 without help of computer algorithms.
متن کاملSulfated derivatives of Escherichia coli K5 capsular polysaccharide are potent inhibitors of human cytomegalovirus.
To date, there are few drugs licensed for the treatment of human cytomegalovirus (HCMV) infections, most of which target the viral DNA polymerase and suffer from many drawbacks. Thus, there is still a strong need for new anti-HCMV compounds with novel mechanisms of action. In this study, we investigated the anti-HCMV activity of chemically sulfated derivatives of Escherichia coli K5 capsular po...
