[Abstract]  Chlamydomonas reinhardtii is a model organism for chloroplast studies. Besides other convenient features, the feasibility of chloroplast genome transformation distinguishes this unicellular alga as ideal for the manipulation of chloroplastic gene expression aiming biotechnological goals, such as improved biofuel and biomass production. Ribulose 1, 5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39, Rubisco) is the photosynthetic carbon-fixing enzyme which is considered crucial for biomass accumulation in algal cultures. Purification of wild type and site-directed mutants of Rubisco in C. ... [摘要]  衣藻衣原体是叶绿体研究的模式生物体。 除了其他方便的特点,叶绿体基因组转化的可行性区分这种单细胞藻理想的操纵叶绿体基因表达瞄准生物技术目标,如改善生物燃料和生物质生产。 核酮糖1,5-二磷酸羧化酶/加氧酶(EC 4.1.1.39,Rubisco)是光合作用碳固定酶,其被认为对藻类培养物中的生物量累积是至关重要的。 Rubisco的野生型和定点突变体的纯化。 通常进行研究其催化性质并评估菌株的碳固定潜力。 在该方案中,通过细胞沉淀的超声处理提取Rubisco,并通过硫酸铵沉淀,蔗糖梯度离心(Goldwaithe和Bogorad,1975)和阴离子交换层析纯化。

Protein Extraction from Drosophila Embryos and Ovaries

[Abstract]  Here we provide the description of protocols to efficiently obtain protein extracts from embryos and ovaries of Drosophila melanogaster. These protocols are routinely applied in our laboratory and are based on two techniques: either embryos or ovaries are homogenized using a pestle and then the soluble proteins separated by centrifugation, or embryos are individually lysed by needle manipulation. The latter technique allows the use of small embryo numbers and the selection of specific developmental stages (Guilgur et al., 2014). [摘要]  FLP / FRT系统是基于将重组酶(翻转酶-FLP)靶向指定为翻转酶识别靶标(FRT)位点的特定DNA区域的定点重组技术。最初在酿酒酵母中鉴定,酵母FLP酶及其FRT重组靶点成功转移到果蝇中的每个主要染色体臂(Golic和Lindquist,1989)。这提供了以受控方式在发育过程中在体内介导有丝分裂重组的能力[在Theodosiou和Xu(1998)中修订]。有丝分裂重组事件的受控诱导通常通过在热休克(hs)启动子的控制下表达FLP来进行。这允许在特定发育时间窗口表达高FLP水平。携带这些遗传标记的FLP / FRT染色体的菌株大大增强了我们在种系和体细胞果蝇组织中研究基因功能的能力。在这里我们描述两种不同的方案:一种用于诱导和鉴定卵巢中的纯合突变体克隆,另一种用于产生雌性种系突变体,用于分析母体对胚胎发生的影响。
