The polysaccharide (PS) derived from K. pneumoniae NCTC 5055 lipopolysaccharide (LPS) was covalently linked to tetanus toxoid by using carbodimide with adipic acid dihydrazide as a spacer molecule. The conjugate was found to be non-toxic and non-pyrogenic at 100 microg dose level. At a similar dose, the conjugate did not elicit any local skin reaction on intradermal preparatory injection in rab...

Supported on activated carbon gold colloidal nanoparticles have been prepared in the presence of stabilizing polymer PVA and PVP (polyvinylalcohol, polyvinylpyrrolidone). The effect to Au weight ratio was investigated, for synthesizing with different particle size distribution. By varying polymer/Au wt/wt ratio, mean diameters from 3 8 nm were synthesized. synthesized catalysts studied liquid p...

A series of high molecular weight copolyesters were prepared from isophthalic acid, 1,4butane diol and sebacic acid/ adipic acid through a two step process of melt polycondensation using titanium tetra butoxide as catalyst. The synthesised random copolyesters were characterised by means of IR, 1H NMR, 13C NMR, gel permeation chromatography (GPC), viscosity measurements, differential scanning ca...

− N,N’-Bis(salicylidene)ethylenediiminocobalt (Cosalen) was encapsulated into the supercage of microporous NaY zeolite via “ship-in-a-bottle” technique. The impregnated Cosalen complex immobilized on the outer surface of the zeolite was also prepared in order to further prove the encapsulation by the flexible ligand method. The samples were characterized by FT-IR, UV-Vis, XRD, TG/DTA and SEM te...

Rat liver 5 S and 5.8 S rRNAs were oxidized with periodate and the 3' termini were coupled to Sepharose 4B through an adipic acid dihydrazide spacer. Ribosomal proteins were passed through the nucleic acid affinity columns to form ribonucleoprotein complexes containing the nucleic acid and the proteins that bind to it (5 S . L6, L7, L19; and 5.8 S . L6, L19, S9, S13). Pure isoaccepting species ...
