1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。

a. eEF2 promotes the GTP-dependent translocation of the ribosome along mRNA during protein synthesis. b. Homology model of Plasmodium falciparum eEF2. The mapped mutations from each strain are colour coded by EC50 fold (red high, amber moderate, green low). c. Live cell imaging of P. falciparum expressing an extra copy of eEF2 (WT) fused to GFP. The image is representative of >50 parasites visualized on two independent occasions. d. Protein and DNA/RNA synthesis were evaluated by measuring the incorporation of [35S]-labelled methionine and cysteine ([35S]-Met/Cys) (upper panel) and [3H]-labelled hypoxanthine (lower panel) into asynchronous 3D7 wild-type (○) and 3D7 DDD107498-resistant line (eEF2-E134A/P754A) (●) after 40 min incubation with DDD107498, cycloheximide or actinomycin D. Radiolabeled incorporation, measured as cpm, was normalised as % of incorporation against inhibitor concentration (means ± s.d.; n=3 independent experiments each run in duplicate). e. The EC50 values for transfectants against DDD107498 (means ± s.d.; n=4-7 independent experiments, each run in duplicate).

Effect of DDD107498 on parasite morphology a. Phenotype of P. falciparum in peripheral blood of NOD-scid IL-2R_null mice engrafted with human erythrocytes. Blood samples were taken at day 5 and 7 of the assay (1 and 2 asexual cycles, respectively) after the start of treatment with vehicle or DDD107498 at day 3. The bidimensional flow cytometry plots measure the murine (Ter-119-PE+) and human (Ter-119-PE−) erythrocytes, and the presence of nucleic acids (infected SYTO-16+ events). The blue circles indicate the region of infected erythrocytes. Vehicle-treated mice showed a characteristic pattern of staining with SYTO-1635, which correlated with the presence of healthy rings, trophozoites and schizonts in blood smears. Conversely, mice treated with DDD107498 at 50 mg/kg showed only trophozoites with condensed cytoplasm and some pyknotic cells at day 5 (red circle in flow cytometry plot and corresponding blood smears). By day 7, few infected erythrocytes were detected by flow cytometry and blood smears revealed parasites with a similar morphology to those at day 5. This suggests that trophozoites are the most sensitive population since the cycle is interrupted at this stage. The images displayed are taken from a mouse with high levels of parasitemia. At least 50 parasites were counted per sample screened in the microscope. Of these, 4 photos of representative parasite phenotype were selected to represent the morphology of the most prevalent phenotype. Thus, this is a qualitative assessment. b. Stage specificity assays using synchronised cultures. For morphological analysis of antimalarial drug action, thin blood smears were prepared, fixed and stained with Giemsa followed by examination with an upright microscope using an oil-immersion lens (100×). For parasitemia determination, a total number of 1000 red blood cells (corresponding to 5 microscopic fields) were counted. R to T. Abnormal trophozoites observed after 24h exposure of synchronized rings to DDD107498. T to S. Trophozoites do not develop into schizonts after 24h exposure to DDD107498. S-R. No ring stages are observed 24h after treatment of schizonts with DDD107498. c. Percentage parasitemia in the red blood cells. R = ring stage, T = trophozoite, S = schizont.

Fitness phenotypes of DDD107498-resistant parasite lines Unmarked Dd2 and DDD107498-selected parasites with various levels of resistance were assessed for growth in a competition assay, relative to a Dd2-GFP reference line. a. Equal numbers of unmarked test lines were mixed with the Dd2-GFP reference, in triplicate wells, and the ratio of non-fluorescent and fluorescent cells assessed by flow cytometry over time. At day 0, all lines had a 1:1 ratio with the Dd2-GFP reference. Increased growth of the test line over the Dd2-GFP reference, which has a slower growth rate than unmarked WT Dd2, would result in an increased ratio of Test:Dd2-GFP. b. Growth assay of 4 different test lines: i) WT Dd2, ii) EF2-E134D, iii) EF2-L775F, and iv) EF2-Y186N, relative to Dd2-GFP. A faster growth rate of WT Dd2 (DDD107498 IC50 0.14 nM) relative to the fluorescent Dd2-GFP line is reflected in an increased ratio over time. The low-level resistant line EF2-E134D (IC50 5.8 nM) did not attain a WT growth rate, and the high-level resistant lines EF2-L775F (IC50 660 nM) and EF2-Y186N (3100 nM) were further impaired. Means ± s.d.; n=4 independent experiments each run in triplicate. Nature . 2015 Jun 18;522(7556):315-20. td> |
