摘要:
Even when used in applications such as electronic materials, display materials, and inks, in which required standards in terms of coloring prevention, long term stability, low impurity content, and the like, are extremely high, the present invention can meet such required standards. The present invention addresses the problem of providing an allylamine (co)polymer which overcomes the limitations of the prior art, undergoes little coloring, contains little impurities and exhibits excellent long term stability; and a method for producing the same. This problem can be solved by an allylamine (co)polymer which has constituent units derived from allylamine and contains sulfuric acid groups in the structure thereof, in which the proportion of the sulfuric acid groups with respect to the total mass of the allylamine (co)polymer is 20,000 ppm by mass or less.

The present invention addresses the problem of providing a novel method for classifying cancer cells by an analysis method in which measurement of the activity of two types of protein kinase is used. Cancer cells are newly classified and drug sensitivity is predicted on the basis of the ratio of the activity of two types of protein kinase derived from the same sample.

A resin-coated flame-retardant fiber yarn (1) of the present invention includes titanium dioxide particles in a range of 4-12 mass% based on the total mass in a resin coating layer (5), and the titanium dioxide particles include first particles having the number average particle diameter in a range of 0.6-1.5 µm and second particles having the number average particle diameter in a range of 0.2-0.4 µm in the mass ratio of the first particles/second particles in a range of 6/4-9/1, thereby having excellent weaving performance, excellent translucency and thermal insulation performance. A resin-coated flame-retardant fiber woven fabric (11) of the present invention is obtained by weaving the resin-coated flame-retardant fiber yarns (1) used as the warp (1a) and woof (1b).
摘要:
Disclosed is a method for measuring a dehydrogenase or a substrate for the dehydrogenase contained in a sample, wherein both thio-NAD or thio-NADP and NAD or NADP are used as coenzymes. The method enables the measurement on the basis of absorbance values obtained in a visible region, and also enables the accurate measurement of a dehydrogenase or a substrate for the dehydrogenase which is contained in a sample at a high concentration.
