Methods The total RNA of leucocyte was extracted 43 allergic vasculitis patients and 24 normal subjects before and after treatment with Trizol reagent and the integrity and concentrations of HLA-DRw53 gene mRNA were determined by agarose gel electrophoresis and UV spectrophotometer after denatured with 1% formaldehyde, the product was transcribed into complementary retroviral synthetic deoxyribonucleic acid, and sequence-specific primers were designed based on the sequences of second HLA-DRw53 gene exon and housekeeping gene glyceraldehyde phosphate-dehydrogenase cDNA.

In this thesis, ribonuclease A was employed as a model protein to understand the formation of correct three-dimensional structure in the refolding of recombinant proteins in vitro. On this basis, the refolding mechanism in vitro was discussed.

本文以核糖核酸酶A為蛋白質(zhì)體外重折疊的模型蛋白最新免费a电影网站，對其體外重折疊過程進(jìn)行了研究，探討了這類目標(biāo)蛋白復(fù)性過程的一些規(guī)律性的問題欧美大片在线免费观看。

Since the famous Anfinsen's experiment on enzyme ribonuclease, it is widely accepted that the correct three-dimensional conformation of a protein is contained in its primary amino acid sequence.

自從1956年著名的Anfinsen的牛胰核糖核酸酶的復(fù)性實驗以來亚洲国产三级AV，人們普遍認(rèn)為：蛋白質(zhì)的三級結(jié)構(gòu)唯一的由其氨基酸序列決定。

According to the alignment of Blastn and Blastx, one differentially exp ressed fragment, A7, was 97% identical in nucleotides to the 26S ribosomal RNA gene of Photinia fraseri and 91% in amino acids to cytochrome P450 monooxygenase in maize, respectively. Another differentially exp ressed fragment, A16, was 85% in nucleotides and 93% in amino acids identical to alpha-expansin 2 in Triphysaria versicolor.
