deletion 中文意思是什麼

Transplantation has been developed to an effctive strategy for treatment of end stage diseases of multiple organs since 1950 ' s. despite success of current immunosuppressive drugs, transplantation immunologists and surgeons are still seeking to achieve tolerance to allograft. there are several different mechanisms such as clonal deletion, anergy, neglect, immuno regulation. which maintain tolerance to self - antigen. some strategies, derived from these mechanisms has been proved to be encouraged in suppression of allograft rejection

二十世紀五十年代以來，器官移植的進展使同種異體器官移植成為治療多種器官終末期疾病的有效手段。盡管目前免疫抑制方案非常有效，但免疫耐受仍是移植免疫學家和外科醫生關注的課題。有多個機制使免疫系統對自身抗原保持耐受，如：克隆清除、忽略、失能、免疫調節。

In this paper, first strand cdna of 3abc gene was synthesized using template rna extracted from cells infected with fmdv. the complete 3abc gene about isoobp was amplified by pcr and ligated into pgem - t easy vector. after transforming e. coli dh5 a, ampicillin resistant colonies were isolated and plasmid dna was prepared and analyzed by restriction analysis and pcr. presence of the full length 3abc gene was verified by nucleotide sequence analysis and the plasmid containing the expected sequence was named as pgem - 3abc. comparing the aquired sequence of 3abc with that of reference strains, the homology is more than 99 percent. the pgem - 3abc was digested with sal i and bgl ii and ligated into xho i and bgl ii - digested expression vector ptriex - 4 neo. lt was identified by restriction analysis and pcr and sequencing that this fragment had a 17bp deletion hi the nucleotide sequence 708bp of 3abc gene, which happened to form a terminator codon behind 3ab gene, but it contained the complete open reading frame ( orf ) of 3ab gene. positive clones were selected and induced with lmmol / l isopropyl - d - galactoside ( iptg ), bacteria were detected by sds - page and western blotting after properly treated. the results showed that the 3ab gene expressed successfully in e. coli and 33. 5ku fusion protein can be recognized by the positive bovine serum of fmdv. the amount of target protein is over 26 % of the total bacteria protein by gel thin layer scanning analysis

2. the sequence of si gene from ibv - lx4 strain was consisted of 1614 bp from initiation codon atg to the possible cleavage site of spike glycoprotein, encoding for a 18 - amino signal - peptide with the n terminus of si protein and a polypeptide of 537 - amino acids. 19 highly conserved, potential glycosylation sites and 17 cysteines residues were characterized with si protein, homology analysis showe that there were gene deletion -

S1基因：其全序列共1614bp （從起始密碼子atg到s前體蛋白裂解位點） ，編碼537個氨基酸，其氨基端有一編碼18個氨基酸的信號肽序列，第12 13位氨基酸殘基構成了信號肽的切割位點， 14 19位與111 124位氨基酸殘基為s1蛋白的跨膜區域。

Shaking flask experiments and hplc analyses showed that the four mutants no longer produced the toxic oligomycin, and only made four components of avermectins b, which were avermectin b1a, b1b, b2a, b2b. the yields of avermectins b in these mutants were separately equal to those in cz8 - 73. this revealed that olma genes deletion did n ' t affect the biosynthesis of avermectins
