Method for removal of triglycerides in lipoproteins other than low-density lipoproteins
10077286 · 2018-09-18 · ·

Disclosed is a method for selectively eliminating triglycerides in lipoproteins other than low density lipoprotein, which method allows one to provide a method for directly and differentially quantifying LDL-TG in a sample with excellent simplicity, specificity and accuracy using an automated analyzer or the like without performing a laborious operation of pretreatment such as centrifugation or electrophoresis. The method for eliminating triglycerides in lipoproteins other than low density lipoproteins includes allowing lipoprotein lipase, cholesterol esterase, glycerol kinase and glycerol-3-phosphate oxidase to act on a sample in the presence of a surfactant that acts on lipoproteins other than low density lipoprotein and/or a surfactant having LDL-protecting action, and eliminating hydrogen peroxide produced thereby.

Size self-limiting compositions and test devices for measuring analytes in biological fluids

A test strip or electrochemical sensor for measuring the amount of an analyte in a biological fluid, e.g. the glucose content of whole blood, includes a size self-limiting reagent formulation employing an enzyme system for reaction with the analyte, the reactive system mixed into a water-soluble swellable polymer matrix containing small water-insoluble particles having a nominal size of about 0.05 to 20 m, preferably about 1 to 10 m. The weight ratio of the water-insoluble particles to the water-soluble swellable polymer matrix is about 1/2 to 2/1. The reagent formulation is deposited onto a non-porous substrate to form a thin layer about 6-16 m thick, providing a rapid and stable response to application of a sample, while being insensitive to the amount of the sample.
