摘要:
The invention concerns a process for stabilizing the enzyme 1-methylhydantoinase (NMHase) which is characterized in that the NMHase is treated with divalent metal ions, a nucleoside triphosphate and a complexing agent which complexes these divalent metal ions. In addition the invention concerns the use of an enzyme stabilized in this way in a method for the determination of an analyte in which 1-methylhydantoin is converted, as well as a corresponding reagent.

A one-component coating composition of35 to 60 wt.-% isocyanate prepolymer8 to 15 wt.-% plasticizer0.3 to 2 wt.-% antisettling agent2 to 10 wt.-% flaky extender5 to 25 wt.-% colorant pigments1 to 3 wt.-% moisture-binding agent, and10 to 20 wt.-% aliphatic estersprovides, on a flexible substrate such as artifical leather, plastic film, paper, roofing felt, polyurethane hard and soft foams, metal foils, concrete and the like, an extraordinarily elastic, tightly adherent coating film of high covering power and light resistance. Furthermore, it has good resistance to abrasion and to weathering, even to aggressive media such as sea water and chemicals.
摘要:
A moisture-setting single-component coating composition has a content of 15 to 70 wt.-% of polyurethane-forming isocyanate, 5 to 25 wt.-% of light-colored, liquid, aromatic hydrocarbon resin of low molecular weight containing hydroxyl groups, 0.2 to 2 wt.-% of antisettling agent, 10 to 35 wt.-% of foliated filler, 2 to 25 wt.-% of tinting pigments, 1 to 5 wt.-% of moisture-binding agent, remainder, but no less than 5 wt.-% of conventional paint solvent. This coating composition can be applied in a conventional manner to a dirt- and dust-free substrate in a thickness of at least 20 microns, and sets of itself by the access of moisture from the ambient atmosphere. The coating composition is suitable especially for the protection of roofs of all kinds, for coating concrete, for protecting reinforced concrete against corrosion, for the painting of steel roofs and/or for the sealing of flat roofs covered with roofing felt.

The present invention relates to the use of a polar organic solvent for the stabilization of a cholinesterase substrate solution, wherein at least one substrate is stabilized by at least one species of a polar organic solvent in a buffered solution, and to the use of said solution for determining the activity of cholinesterase in a sample. Also within the scope of the present invention is a stabilized cholinesterase substrate solution for determining the activity of a cholinesterase in a sample, wherein at least one substrate is stabilized by at least one species of a polar organic solvent. Furthermore, the invention relates to a method for determining the activity of a cholinesterase in a sample, as well as a kit for determining the activity of a cholinesterase in a sample and a kit for conducting a method for determining the activity of a cholinesterase in a sample.
摘要:
A stabilized reagent for the photometric enzymatic determination of creatine kinase (CK) in biological sample material by forming ATP from creatine phosphate and ADP and detecting the ATP formed, containing an organic or inorganic sulphur compound preferably in a submolar amount relative to the added CK activator. A corresponding reagent in a liquid form is stable at 2 to 8° C. for up to 12 months without significant loss of function.
摘要:
In a method for the production of melt-bonding wires to enable the use of non-solvent-containing thermoplastic or thermosetting coating materials, meltable thermoplastic or thermosetting materials are supplied to a fusion chamber (8) where they are melted. The insulated electrical conductor (1) to be coated is drawn through the melt and after the coating process leaves the coating chamber (12) through a calibration device (5), which is followed by cooling.
