Chicken IL-15(ChIL-15), Which was discovered in 2001, plays a main role in activating NK cells and CD8+ memory T cells, and may therefore have potential as a vaccine adjuvant.According to published ChIL-15 gene sequence, a pair of primers were designed and synthesized to clone ChIL-15 cDNA from ConA-activated chicken splenocytes by RT-PCR. Recombinant plasmid pUC19ChIL-15 carrying the ChIL-15 gene was constructed. The gene encoding mature ChIL-15 (mChIL-15) was amplified from pUC19ChIL-15 by PCR and cloned into pMD 18-T vector. After digested with Kpn I /Pst I , the mChIL-15 gene was subcloned into prokaryotic expression vector pPRoEX橦Ta and transformed into E.coli DH5a .The transformant was induced by IPTG, and the recombinant ChIL-15(rChIL-15) was expressed as a fusion protein with a histidine hexamer tag at the N-terminal end of the protein. Following expression, the protein was purified by ProBond?Nickel-Chelating Resin. The uninduced and induced protein lysates and the purified protein were separated by SDS-PAGE and transferred onto nitrocellulose membrane to identify rChIL-15 by Western blot. The rChIL-15 was used to immune the guinea pig to obtain rChIL-15 polyclonal antibody.

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.
