Reaction of the novel thiopropyl-closo-1,2-carborane ligand bearing a pendant glycerol group HS(CH(2))(3)CB(10)H(10)CCH(2)OCH(CH(2)OH)(2)(L) with the labile platinum(ii) precursor [Pt(MeCN)(terpy)](OTf)(2)(terpy = 2,2':6',2''-terpyridine; OTf = trifluoromethanesulfonate) affords the highly water-soluble platinum(ii) complex [PtL(terpy)]OTf, the first example of a metal-carborane complex functio...

A method for immobilization of papain has been selected based on the interaction between its histidine, cysteine and tryptophan residues with the immobilized metal ion (IMI) carrier for maximum binding on a small volume of the carrier. The immobilized papain retained high activity has improved thermal stability and the carrier could be recovered from the spent bound enzyme, to be reused. Reimmo...

1. Heparin, heparan sulphate, chondroitin sulphate and dermatan sulphate were covalently attached to beads of agarose activated by cyanogen bromide. The bond is probably mediated by the amino group of a serine or peptide residue at the reducing end of the polysaccharide chain. 2. The uptake of glycosaminoglycan during the coupling procedure is about 0.9mg/ml of wet gel. However, direct analysis...

The recently discovered contamination of oral rotavirus vaccines led to exposure of millions of infants to porcine circovirus (PCV). PCV was not detected by conventional virus screening tests. Regulatory agencies expect exclusion of adventitious viruses from biological products. Therefore, methods for inactivation/removal of viruses have to be implemented as an additional safety barrier wheneve...

Site-specific S-glutathionylation is emerging as a novel mechanism by which S-nitrosoglutathione (GSNO) may modify functionally important protein thiols. Here, we show that GSNO-Sepharose mimicks site-specific S-glutathionylation of the transcription factors c-Jun and p50 by free GSNO in vitro. Both c-Jun and p50 were found to bind to immobilized GSNO through the formation of a mixed disulphide...
