分配物
6.Something, such as a boundary or partition, that serves to divide or keep separate.
7.If a group of howitzers is selected, the targets are divided among them, i.e. each target object is only fired at by one howitzer.
8.One that dispenses or gives out, especially a machine or container that allows the contents to be removed and used in convenient or prescribed amounts.
9.removed and used in convenient or prescribed amounts
10.A novel aqueous two-phase system can be formed by the mixtures of a polymer and cationicanionic surfactants.Such a system can be used as a partitioning system of proteins.In this work,we investigated the formation,phase behavior and protein partitioning in aqueous two-phase systems formed by dodecyltriethylammonium bromide/sodium dodecylsulfate/PEG and dodecyltriethylammonium bromide/sodium dodecylsulfate/dextran.The ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated.It was shown that the surfactants and polymers are enriched in different phases of aqueous two-phase systems.Phase separation are promoted by increasing temperature and adding inorganic salts.Different proteins are partitioned in different phases.The selectivity of protein partitioning is increased by adding ligands with affinity.
