Treatment with solvent/detergent is a widely used method for ensuring the virus safety of plasma products. In the present study, virus inactivation by a novel solvent/detergent combination, i.e. TnBP (tri-n-butyl phosphate) and polysorbate 20 during the manufacture of the factor VIII/VWF concentrate Optivate has been investigated. The inactivation of most enveloped viruses was rapid, i.e. > 5 l...

The paper presents the results of the influence of anionic-type detergent containing sodium tripolyphosphate and ethoxylated oleylcetyl alcohol on the type and quantity of present amino acids in the fermentation broths of the fungi Aspergillus niger, Alternaria tenuis and Fusarium oxysporum cultivated on a medium with the addition of 1% detergent as a function of their application in the proces...

Two pools of heparan sulfate proteoglycans have been selectively solubilized from rat liver plasma membranes by successive incubations with heparin and detergent. The two populations of proteoglycans have similar polyanionic properties as indicated by identical elution positions on ion-exchange chromatography on DEAE-Sephacel but differ in buoyant density in CsCl when analyzed by density gradie...

Lipases are the enzymes of choice for laundry detergent industries owing to their triglyceride removing ability from the soiled fabric which eventually reduces the usage of phosphate-based chemical cleansers in the detergent formulation. In the present study, a partially purified bacterial lipase from Staphylococcus arlettae JPBW-1 isolated from the rock salt mine has been assessed for its trig...

Although detergents are often essential in protocols, they are usually incompatible with further biochemical analysis. There are several methods for detergent removal, but the procedures are complicated or suffer from sample loss. Here, we describe a convenient and rapid method for detergent removal from sialic acid-containing glycosphingolipids (gangliosides) and neutral glycolipids in deterge...

This study aimed to compare the social compatibility of male and female students in PNU of Dareshahr. The population in this study included 41 male and 59 female PNU students in the school year of 2013-14 who were selected randomly. The California social-individual compatibility questionnaire was used in order to measure the variables. For this purpose a comparative plan was applied and a T-tes...
