A recombinant protein of Bla g 2 has been obtained, which is soluble in the supernatant and therefore can avoid a process of denaturalization and renaturation of the recombinant.

获得了真核表达的德国小蠊主要变应原重组蛋白Bla g 2，该蛋白以可溶性蛋白的形式分泌到培养液中，避免了原核表达的变复性过程。

But the interest protein was still expressed intracellularly. In this study, we have constructed expression vectors. Bovine IL2 has been expressed in Pichia pastoris, but in a fused protein form existing intracellularly. The effection of signal peptide and its procession on foreign protein secretion have been studied.

总之，本研究通过不同构建策略的表达载体的构建，实现了目的蛋白在真核体系中的表达，但以融合蛋白的形式存在于胞内，通过不同信号肽和信号肽加工位点的构建，探讨了影响目的蛋白有效分泌的原因。

In our previous work, we found that RIG-G could interact with JAB1 and sequestrate the later in the cytoplasm, preventing JAB1 from facilitating the phosphorylated p27 nuclear export and degradation via the cytoplasmic ubiquitin/ proteasome pathway.

在以前的工作中，我们曾发现RIG-G可以与JAB1蛋白发生相互作用，并将后者阻滞在细胞浆中，无法正常携带磷酸化的p27蛋白出核，从而抑制了p27蛋白通过胞浆的泛素/蛋白酶体系统降解。

Purified protein samples were separated by 2-DE with 17 cm IPG strips, and the protein spots were detected by fast silver staining. Six protein spots were randomly excised from the silver stained gel for primary analysis by MALDI-TOF MS. Four proteins were identified, and they were 1-aminocyclopropane-1-carboxylate synthase 2, ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit, F11O4.2 and Rubisco small subunit.

根据预实验结果，选用17 cm IPG预制干胶条对纯化的蛋白样品进行2-DE实验，采用快速银染法进行染色，随机挖取银染胶上6个蛋白点进行MALDI-TOF MS分析和数据库检索，鉴定了3个蛋白，它们是：1-氨基环丙烷-1羧酸合酶2，核酮糖-1，5-二磷酸羧化酶/加氧酶大亚基和F11O4.2。

The 58?kD protein reacts with anti-vimentin antibody and locates near the aboral wreath cilia.

There were on unique different protein observed in flag leaf at different development stage; but unique different protein were found in anther at binucleated stage and the male-sterile materials lack a 31 kD polypeptide compared with normal material.

结果表明，从不同发育时期的旗叶可溶性蛋白中尚未发现特异蛋白的存在，但在花药中发现有特异蛋白的存在，表现在二核期生理型雄性不育界遗传型雄性不育材料均比正常的可育材料缺少了1条分子量为31kD的多肽。

Objective to evaluate the functional recovery of acute spinal cord injuried rats treated with exogenous wnt-3a signal protein administration and to explore its mechanism.methods moderate spinal cord contusion injury was made in 40 adult sprague dawley rats at t10.twenty rats served as contusion controls(group 1).twenty rats were treated with wnt-3a for three days after injury (group 2).the functional recovery of the rats was observed through basso,beattie,bresnahan open field locomotor score.rats were killed at 14 or 28 days after injury,then spinal cords were removed for histopathological examinations,and the expression of the bromodeoxyuridine plus neural cell markers was stained with immunohistochemical method.results rats of two groups receiving a contusive injury recovered substantial function within 1 week.by 28 days,rats in groups 2 scored 7.0 points better on the bbb scores than rats in group 1 group 2=16.94,after 28 days vs.

目的 研究外源性wnt-3a信号蛋白对脊髓损伤的修复作用，并探讨其作用机制。方法取40只成年雌性sd大鼠在t10节段制备适度脊髓挫伤模型。随机从中取20只为损伤对照组(group 1)，另外20只为损伤治疗组(group 2)。脊髓损伤3天后用wnt-3a蛋白治疗。这些大鼠的功能恢复通过basso、beattie、bresnahan开放视野运动评分来观察。这些大鼠分批在损伤后14天或28天被处死，取出损伤节段脊髓用来组织病理学检查，同时用5-溴脱氧尿嘧啶核苷和神经细胞标记物进行免疫组化染色。结果两组大鼠在伤后一周运动功能有明显的恢复。不过，到损伤后28天，我们观察发现，损伤治疗组中的大鼠bbb评分比损伤对照组中的评分高出7.0分左右(group 2∶16.94±1.18，group 1∶9.89±1.29；p.05)，光镜和电镜检查发现wnt-3a蛋白对髓鞘形成和轴突再生有一定的修复效果。

Using cytochalasin D to prevent global actin from forming filamentous structures, the production of Heliothis armigera nuclear polyhedrosis virus in Hz-AM1 cells grown in the medium containing 0.5μg/ml CD was completely inhibited while its production was reduced to 10〓 in the presence of 0.1μg/ml CD by plaque assay. However, Western blotting revealed that the actin quantity in infected host cells treated or untreated with CD was almost identical. Additionally, CD had no effect on the DNA synthesis of HaNPV.

Western blot表明细胞松弛素D并不影响受染细胞中肌动蛋白的含量，Dot blot表明病毒DNA的合成也没有受到影响，但电子显微镜超薄切片发现在0.5ug／mL细胞松弛素D中形成的病毒粒子形态与正常的有明显区别，认为细胞松弛素D抑制棉铃虫核型多角体病毒的增殖是因为抑制病毒的DNA和蛋白组装成完整有感染性的病毒粒子，即丝状肌动蛋白对病毒粒子的脱壳和DNA的复制、转录没有影响，但对病毒粒子的组装是必须的。

The result of homological analysis showed that an open reading frame,which contains 289 amino acids,is more similar to the Choristioneure fu- m...

Comparison from the Germany isolate, phocine distemper virus type Ⅱ(PDV-2) and vaccine strain, the major difference is the long signal peptide domain while the mature protein exhibit high identity, and all of the 13 serine residues, four potential asparagine glycosylation sites and two hydrophobic regions supposed to affect the fusion function are completely identical. These data supports the view that F protein is more conservative than H protein in CDV.
