以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比；如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象，可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請依序添加每種溶劑： 5% DMSO    40% PEG300    5% Tween-80    50% Saline

    Solubility: ≥ 5.75 mg/mL (15.56 mM); 澄清溶液

  • 方案 二

    請依序添加每種溶劑： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (5.63 mM); 澄清溶液

    此方案可獲得 ≥ 2.08 mg/mL（飽和度未知）的澄清溶液。

    以 1 mL 工作液為例，取 100 μL 20.8 mg/mL 的澄清 DMSO 儲備液加到 400 μL PEG300 中，混合均勻；再向上述體系中加入 50 μL Tween-80，混合均勻；然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL。

    生理鹽水的配制：將 0.9 g 氯化鈉，溶解于 ddH?O 并定容至 100 mL，可以得到澄清透明的生理鹽水溶液。

Cell Assay
[2]

Cell survival is determined using the MTT assay. The conversion of yellow water-soluble tetrazolium MTT into purple insoluble formazan is catalyzed by mitochondrial dehydrogenases and used to estimate the number of viable cells. In brief, cells are seeded in 96-well tissue culture plates at a density of 2×103 cells/well. After drug exposure, cells are incubated with 0.4 mg/mL MTT for 4 hours at 37°C. After incubation, the supernatant is discarded, insoluble formazan precipitates are dissolved in 0.1 mL of DMSO, and the absorbance is measured at 560 nm by use of a microplate reader. Wells with untreated cells or with drug-containing medium without cells are used as positive and negative controls respectively. For proliferation assay, MTT assay is done daily to determine the number of viable cells in untreated control andGalunisertib (LY2157299) (0.1, 1, 10, and 10 μM)-treated group[2].

Animal Administration
[3]

Mice[3]
Charles River nude mice (weight 25 mg) are used. Galunisertib (LY2157299) is given orally as a single dose or in a multiple dosing design. The value of the dose levels given in a single dose manner is 10 (n=3), 30 (n=8), 50 (n=26), 75 (n=69), 100 (n=3), 150 (n=21) and 300 (n=3) mg/kg. Animals are sacrificed at the following times: 0.5, 1, 1.5, 2, 4, 8 and 16 h after administration, then the tumor is removed and blood is recovered. In the multiple dosing study, Galunisertib (LY2157299) is administered twice a day (bid) at the dose of 75 mg/kg every 12 h for 20 consecutive days to 31 mice. Animals are sacrificed at 2 h after the last administration at days 10, 15, 20 and 25, and the tumor is removed for pSmad determination and the blood is recovered for determination of drug levels in plasma.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
