From oxypropylated olive stone towards novel polymeric materials

Marina Matos、Maria Filomena Barreiro、Alessandro Gandini2011-01-01Portuguese National Funding Agency for Science, Research and Technology (RCAAP Project by FCT)

The oxypropylation of OH-bearing substrates constitutes an original approach to the rational exploitation of the biomass. Total oxypropylation of a variety of natural polymers, including chitosan and chitin residues, different types of lignins, cork and more complex structures like sugar beet pulp, converts these soli…

The growth and deformation of cobalt crystals

K. G. Davis2011-01-01cIRcle (University of British Columbia)

Cobalt crystals of commercial purity have been grown in an electron beam zone refiner. They were tested in tension at temperatures between 150°C and -196°C. The resolved shear stress—shear strain curves are similar in form to those for the high stacking-fault energy hexagonal metals zinc, cadmium, and magnesium. There…

细菌蛋白质组双向电泳中“串联珠”现象初探

胡威、朱力、商娜 等 8 位作者2011-01-01Acta Scientiarum Naturalium Universitatis Sunyatseni

目的初步探讨细菌样品双向电泳中'串联珠'状蛋白点产生的原因。方法通过对比不同样品制备方法对双向电泳胶图的影响,分析'串联珠'状蛋白点出现的条件,并取'串联珠'状蛋白点进行胶内酶解及MALDI-TOF/TOF分析,寻找'串联珠'状蛋白点可能产生的原因。结果以含0.5%SDS的裂解液煮沸菌体的方法制备样品,就会产生'串联珠'状蛋白点。蛋白鉴定结果显示'串联珠'状蛋白点为同一蛋白,MALDI-TOF/TOF一级质谱峰没有出现明显的偏移峰。结论 '串联珠'产生的原因是由于SDS在加热条件下会对蛋白产生修饰或紧密结合作用,特别是相对分子质量较大的酸性蛋白。
