So we understand to once and actually usually take place of the bad factory house adds plant egg white(soybean egg white etc. corn egg white) in the origin should be the milk powder of animality egg white, this is already the first floor to cheat and commit crime, dishonest at least, but the widespread phenomenon in the in view of the fact industry, and have no obvious side effect to the human body, therefore is connive;But the protein content in the original inferior product very low, unexpectedly meet more unscrupulous plant egg white raw material to provide a company, add three gather cyanotype An, result in as a result currently result;Here our for the time being imagining is the beperhaps havior of the supplier, perhaps is three deer companies have intention to add, the basic reason for add lies in a current Kai surname settle nitrogen protein measurement method can test an always organic nitrogen content, rather than the nitrogen content in the particular protein, therefore, the method blemish was fume by the cupidity the exploitation that the milk powder manufactories of heart speculate, make the false and inferior product deceive to reach to mark, because they know three chlorine cyanotype An toxicities are again very small, disguise a protein content to reach a mark in the examination, but they didn't thought of that the toxicity is pimping three chlorine cyanotype An exactly will bring serious Bi to baby kid to wet system stone calculus, we even can guess, other adults of three deers use a milk powder in must also imply in great quantities similar chemistry product, just the adult will not get instant results of is endanger by body.
那么我们了解一下,实际上经常发生的不良厂家在本应该是动物性蛋白的奶粉里添加植物蛋白,这已经是第一层欺骗和犯罪,至少是不诚实了,但由于是业内的普遍现象,且对人体无明显副作用,因此被默许;而本来劣质产品中蛋白质含量就很低,没想到遇到更缺德的植物蛋白原料提供商,添加三聚氰胺,结果造成目前后果;这里我们姑且想象也许是供应商的行为,也许是三鹿公司有意添加,添加的根本原因在于现行的凯氏定氮蛋白质测定方法只能测试总有机氮含量,而非特定的蛋白质中氮含量,因此,方法缺陷被利欲熏心的奶粉制造商们所投机利用,使伪劣产品蒙混达标,因为他们知道三氯氰胺毒性很小,又能在检测中伪装蛋白质含量达标,但他们就没有想到毒性很小的三氯氰胺却恰恰会对婴幼儿造成严重的泌尿系统结石,我们甚至可以猜测,其它三鹿的成人用奶粉中一定也含有大量类似化学制剂,只是成人不会立竿见影的受到身体危害。

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 minor core protein s C-encoding gene of Muscovy duck reovirus was cloned into theprokaryotic expression vector pET32a. The recombinant plasmid pET32a-s C was amplified andextracted after being transformed into E.coli DH5a competent cells. Restriction analysis withEcoRⅠand SacⅠand sequences analysis indicated that the recombinant plasmid was inserted withcorrect open reading frame.

The SDS-PAGE andWestern-bloting test indicated that the fusion protein reacted with the convalescents sera of duckinfected with Muscovy duck reovirus. The indirect ELISA method was developed by using thepurified fusion s C protein as coating antigen. The optimal concentration of s C was 5μg/ml, thedilution of serum sample was 1:40; The results showed that preparation of an ELISA by using sCas coating antigen in detecting 50 field duck sera in comparison with the AGIP were more sensitiveand specific than agar gel immuno-diffusion AGIP test. The results suggest that presence ofantibody against viral protein sC in duck may be a good indicator by the sC-ELISA for detectionof duck infection with reovirus.

After amplying a 2.2kb fragment form the PPV-SC1 RF-DNA,we clone the fragment into pMD 18-T,named pTNSl.The whole sequence which is 1989 bp long was determined by sequencing, including the complete ORF of PPV-SC1 NS1 which encoding 662 amino acids.Alignment of pairs of sequence indicates that there are 98% and 99% similary with other porcine parvovirus strains Kresse and NADL-2, respectively. Multiple sequence alignment discloses that there are a few difference between ppv-scl nsl gene and other ppv nsl gene: A-G at 39nt,T-C at 153nt,A-G at 175nt, A-C at 1117nt, A-C at 1535nt .Alternative codon in ppv-scl nsl have distinctly different frequentfy by codonbias analysis at EMBOSS(http://genopole.toulouse.inra.fr/bioinfo/emboss). Thereis not distinct hydrophobicity and transmenbrane helices in ppv-scl nsl protein. Struction domain anslysis of PPV-SC1 NS1 protein indicate that there are a ATP/GTP-binding site motif A at 398-405,16 Protein kinase C phosphorylation site,21 Casein kinase II phosphorylation site,and 3 cAMP/cGMP-dependent protein kinase phosphorylation site.At the same time ,there is a same motif between ppv-scl nsl and Poxvirus D5 protein-like which may share in the same fuction which is necessary during virion duplication.
