Analysis of d--Aspartyl Isomers at Specific Sites in Proteins

Recent studies have shown that biologically uncommon d -β-aspartic acid residues accumulate in specific proteins during the aging process. However, aspartyl residues are not racemized uniformly because d -Asp appears to be confined

波尔多液(bordeaux mixture)

保护性无机铜杀菌剂。在硫酸铜与生石灰分别为1kg、水为100kg配制时，称为等量式波尔多液，生石灰为硫酸铜的一倍时，称为倍量式波尔多液；反之，石灰的量为硫酸铜的1/2时，称为半量式波尔多液。 是一种含有极小蓝色粒状悬浮物的液体。对金属有腐蚀作用。对温血动物低毒。与硫酸铜、碱式硫酸铜和王铜等无机铜制剂比较，具有良好的展着性和粘着力，在植物表面可形成薄膜，不易被雨水冲刷，残效期比较长，对作物比较安全。 广泛用于防治大田作物、蔬菜、果树和经济作物病害，在病原

Selective Primer Sequencing from a DNA Mixture by Capillary Electrophoresis

DNA analysis methods have been greatly developed in the past 10 yr with the progress of the Human Genome Project (1 ). In addition to rapid and high-throughput DNA sequencers (2 ), various reagents (3 ), and sample preparation methods
