Abstract: The present invention is directed to a composition comprising a vanadium-containing phosphatase inhibitor and a polyol. In the presence of the polyol the effect of the inhibitor is enhanced, even in the presence of chelating agents or reducing agents. The invention also concerns the use of the inventive composition for inhibiting a phosphatase, as well as kits comprising the composition.

Abstract: The present invention concerns a method for producing a lysate containing helper proteins in which a strain which is suitable for obtaining in vitro translation lysates is transformed using a vector containing one or more genes coding for one or more helper proteins, wherein the helper proteins are expressed in this strain and the lysate containing helper proteins is obtained from these strains. The present invention also concerns a lysate containing helper proteins that can be obtained by the method according to the invention, blends of these lysates and the use of these lysates and blends in in vitro translation systems.

Abstract: A process is provided for inhibiting serine proteases in a sample. The process involves adding to the sample a compound such as cresol or 3-hydroxypyridine and then adding to the sample a sulfonic acid derivative or a fluorophosphonate, to derivative the serine proteases. The compounds such as cresol or 3-hydroxypyridine avoid nonspecific derivatization of proteins other than the serine proteases.

Abstract: The invention concerns compounds which have a chromophore and a group capable of binding to streptavidin or/and avidin and which are suitable for binding to molecules containing an aldehyde, ketone, hemiacetal or/and hemiketal group. In addition the invention concerns conjugates formed from these compounds as well as a method for the detection or isolation of carbohydrates or glycan receptors by means of such conjugates.

Abstract: The invention concerns new cationic or polycationic amphiphiles which are capable of forming aggregates with macromolecules, in particular with DNA or RNA, and it concerns their delivery into prokaryotic or eukaryotic cells. Compounds with spermyl-dioleoyloxypropyl structure have proven to be particularly preferable.
