摘要:
A contact leveling surface for an ink jet imaging member comprising a low adhesion coating, wherein when the low adhesion coating is disposed on a contact leveling surface, jetted drops of ultra-violet gel ink exhibit a low sliding angle with the contact leveling surface, wherein the low sliding angle is less than about 1° to less than about 30°.
摘要:
The present invention is directed to nucleic acids delivery systems and methods of modulating an expression of a target gene using the same. In particular, the invention relates to nucleic acids conjugates containing an endosomal release-promoting moiety. The nucleic acids conjugates further contain a nuclear localization signal moiety, and/or a cell targeting moiety.

摘要:
The present invention is directed to methods of preparing linear polymers such as polyalkylene oxides containing a terminal amine in high purity. One preferred method includes reacting a polyalkylene oxide such as polyethylene glycol containing a terminal azide with a phosphine-based reducing agent such as triphenylphosphine or an alkali metal borohydride reducing agent such as sodium borohydride in a solvent to reflux. The resultant polymer-amines are of sufficient purity so that expensive and time consuming purification steps required for pharmaceutical grade polymers are avoided.
摘要:
The present invention provides polymeric siRNA conjugates. Methods for down-regulation of gene expression in vivo and in vitro and for inhibition of the growth of cancer cells using the conjugates are also disclosed.
摘要:
A blood vessel metal stent coating of amidoglucosan polysaccharide loaded with antibody comprises carrier material composed of chitosan and inartificial degradable acidic amidoglucosan polysaccharide and the effective dose of CD133 antibody loaded in the carrier material. The blood vessel metal stent coating is manufactured with self-assemble method to fix the CD133 antibody in the carrier material of the coating. The coating has good biocompatibility, water retention property, flexibility, flush resistance and bio-stability, and can specifically capture the vascular endothelial progenitor cells in human peripheral blood, and differentiate into vascular endothelial cells. The process would accelerate endothelialization to repair injured vessel caused and prevent restenosis and thrombosis efficiently.
