• Continuous process for phosphorylating starch
  申请人：National Starch and Chemical Corporation

  Starch is phosphorylated by a virtually pollution-free, continuous process whereby an aqueous reagent solution of a tripolyphosphate, orthophosphate or pyrophosphate salt or a mixture thereof is sprayed onto a moist starch cake on a rotary vacuum filter in an amount sufficient to achieve efficient impregnation of the starch cake without losing significant levels of salt to the effluent. In a preferred embodiment, the reagent solution contains alkali metal tripolyphosphate salt and is obtained by diluting a concentrated solution thereof. The thus-impregnated starch is subsequently dried and heat-reacted by known procedures to produce an orthophosphate starch monoester.

  淀粉可以通过一种几乎无污染的连续过程进行磷酸化，该过程中，将三聚磷酸盐、正磷酸盐或焦磷酸盐的水溶性试剂溶液或其混合物喷洒到旋转真空过滤器上的湿淀粉蛋糕上，以达到高效浸渍淀粉蛋糕的目的，同时不会使盐的水平显著降低。在一种优选实施方式中，试剂溶液含有碱金属三聚磷酸盐，并通过稀释浓缩溶液获得。随后，经过已知的程序对浸渍的淀粉进行干燥和热反应，以产生正磷酸酯淀粉。

  A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3 H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.

  本文描述了一种DNA测序系统和方法，用于检测不同激发染料标记的物种（DNA片段）分离后发出的辐射能量的存在，并且在时间和/或空间上，以及在波长密集的发射能量的物种的身份上，获得变化的发射能量的功能。通过对函数进行比率，比率表明DNA片段的身份。最好的发射染料标记DNA片段的发射部分是基于9-羧基乙基-6-羟基-3-氧代-3H-黄酮的荧光染料家族之一。这些黄酮染料通过羧酸功能与DNA片段共价连接，最好通过酰胺连接。染料可以通过在9位点包括烷氧基来保护。染料和胺之间可以插入一个间隔物。荧光染料最好连接到DNA链终止子上，并提供许多优点。因此，只有由真正终止事件产生的DNA测序片段才会携带报告者。DNA测序也可以使用具有荧光标记通用性的黄酮染料进行标记。此外，本文还介绍了使用Sanger方法的改进来使用无环核苷酸三磷酸盐作为DNA测序中的链终止剂的方法。

  This invention involves new compositions and methods of use and delivery of amorphous calcium compounds such as: amorphous calcium phosphate (ACP), amorphous calcium phosphate fluoride (ACPF), amorphous calcium carbonate phosphate (ACCP), amorphous calcium carbonate phosphate fluoride (ACCPF), and amorphous calcium fluoride (ACF) for use in remineralizing and fluoridating teeth. These amorphous compounds or solutions which form the amorphous compounds or calcium phosphate jelly which forms the amorphous compounds, when applied either onto or into dental tissue to prevent and/or repair dental weaknesses such as dental caries, exposed roots and dentin sensitivity. The compounds have the highest solubilities, fastest formation rates and fastest conversion rates (to apatite) among all the calcium phosphates under physiological conditions. Moreover, in the presence to fluoride the amorphous compound convert rapidly to fluoride containing apatite.
