    摘要： Glycerol dehydrogenase enzymes having exeptionally good thermal stability are produced by culturing novel strains of Bacillus stearothermophilus. Procedures for deriving and identifying suitable strains are described. The strains are grown in conventional culture media, preferably containing 0.05 to 4.0%, especially 0.1 to 1.0%, by weight of glycerol or a glycerol analogue at 40.degree.-65.degree. C. and pH 5 to 8. The enzyme is isolated by conventional cell disruption and separation techniques, and typically has a molcular weight of 240,000.+-.30,000, composed of four similar sub-units, and a specific activity of greater than 5 Units per mg protein at 30.degree. C. by the modified assay described. They may be stored as aqueous solutions or a freeze dried solids.The enzymes may be used for assay of serum triglycerides by conventional assay methods, but preferably by the nictotinamide adenine dinucleotide spectrophotometric assay at a pH of 7 to 8.8. The pH is preferably controlled by an amine, especially triethanolamine/HCl, buffer.

    摘要： Affinity chromatography media are prepared by reacting mono or di-chloro triazine dyes with a solid support matrix containing free hydroxy or amino groups in the presence of an alkali metal hydroxide and an alkali metal salt. In the absence of cyanogen bromide activation, the linkage to the support is entirely via the triazine ring giving high and specific protein-binding capacity. Suitable support matrices include polymers and copolymers of agarose, dextrose, dextran and acrylamide with agarose being particularly preferred. Dye binding levels are much higher than those obtained in the presence of carbonates or bicarbonates.Mono-chlorotriazinyl dyes are bound at a pH which is preferably above 9.5. The reaction time is about 40-60 hours at room temperature, however this may be reduced if the reaction temperature is increased. Dichlorotriazinyl dyes are bound at pH 8 to 12.5 in a few hours at room temperature.The media may be used for the efficient and often highly specific purification of a wide variety of proteins, including enzymes and blood proteins.

    摘要翻译： 通过在碱金属氢氧化物和碱金属盐的存在下，使单或二氯三嗪染料与含有游离羟基或氨基的固体支持基质反应来制备亲和层析介质。 在没有溴化氰活化的情况下，与载体的连接完全是通过三嗪环提供高和特异性的蛋白结合能力。 合适的载体基质包括琼脂糖，葡萄糖，葡聚糖和丙烯酰胺与琼脂糖的聚合物和共聚物是特别优选的。 染料结合水平远高于在碳酸盐或碳酸氢盐存在下获得的结合水平。 单氯三嗪染料在优选高于9.5的pH下结合。 反应时间在室温下约为40-60小时，但如果反应温度升高，则反应时间可能会降低。 二氯三嗪染料在室温下几小时内在pH 8至12.5下结合。 培养基可用于多种蛋白质（包括酶和血液蛋白质）的有效且经常高度特异性的纯化。
