常见问题解答
购买多次产品,发现颜色不同,怎么办?
首先请您确认批次,如果是同一个批次产品,请联系技术同事核查产品颜色。如果是不同批次,请您放心,颜色不同可能是生产工艺不同而造成的,生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑,可在官网下载相应的质检报告,我们是对产品质量负责的。
小规格产品,收到瓶子后看不到任何东西?
由于产品规格小,粉末在运输过程中产生的静电导致过于分散,管壁和盖子上皆会粘着,您可以放心,离心后加入适量溶剂直接配制母液、充分溶解即可。
动物实验常用溶解方法?
首先,您需要确认给药剂量、给药方式。对于具体的产品,优先找引用我们产品的文献里的使用方法,再找其他文献里的配方。 如果没有相关的文献,且该化合物的 DMSO 溶解度比较好,我们推荐通用配方: 10% DMSO+40% PEG300+5% Tween-80+45% Saline/PBS/ddH2O。溶剂依次加入,尽量溶解后再加入下一个溶剂。正常鼠建议 DMSO 浓度在 10% 以下,裸鼠体弱鼠等配方的 DMSO 浓度建议在 2% 以下,根据溶液是否澄清,助溶剂 PEG300、Tween-80 的比例可以适当调整。如果有其他助溶剂也可以使用。 以上配方仅供参考,体内配方并不是绝对的,需要根据不同情况进行调整。建议先取少量化合物测试配方,再进行大量配制。配完也可以再使用超声、加热等方式助溶,看看能不能澄清一点。 腹腔注射对粉末的溶解度要求比较高,建议购买盐形式化合物。如果给药剂量比较大,也有报道使用混悬液进行腹腔给药的。 对于灌胃给药,且剂量比较大的情况下,建议用 0.5% CMC-Na 配置成均匀混悬液进行给药。
产品的溶解度是多少?
建议您先查询TargetMol官网、陶术官网,看该抑制剂的产品介绍,找到溶解度信息。如果没有相应信息,建议联系技术对该化合物的溶解度进行测定。
抑制剂能否用于细胞实验?
可以的,我们的抑制剂都可以用于细胞/体外实验。但有些化合物还没有用于细胞实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。

激酶实验
HTRF In vitro Profiling Assays for PI3K Inhibition : Compounds are serially diluted (3-fold in 100% DMSO) across a 384-well polypropylene mother plate from column 1 to column 12 and column 13 to column 24, to yield 11 concentrations for GSK2126458. Columns 6 and 18 contain only DMSO. Once titrations are made, 0.05μL is transferred to a 384-well low-volume assay plate. This assay plate contains three pharmacological controls (known PI3K inhibitors) and 3 assay controls: (1) Enzyme without inhibitor; (2) Buffer minus enzyme, and (3) Buffer minus enzyme plus native PIP3. DMSO is stamped into all wells of columns 6 and 18. PIP3 is added at 40 μM in 1X Reaction buffer (1μL of 200 μM PIP3) to alternating rows of column 18 (wells 18 B, D, F, H, J, L, N, P). The no-enzyme control reactions are run in wells 18 A, C, E, G, I, K, M, O (0.1μL of 100% DMSO). The PI3-Kinase profiling assay is optimized using the HTRF kit. The assay kit contains seven reagents: 1) 4X Reaction Buffer; 2) native PIP2 (substrate); 3) Stop A (EDTA); 4) Stop B (Biotin-PIP3); 5) Detection Mix A (Streptavidin-APC); 6) Detection Mix B (Eu-labeled Anti-GST plus GST-tagged PHdomain); 7) Detection Mix C (KF). PI3Kinase Reaction Buffer is prepared by diluting the stock 1:4 with de-ionized water. Freshly prepared DTT is added at a final concentration of 5 mM on the day of use. Enzyme addition and compound pre-incubation are initiated by the addition of 2.5μL of PI3K (at twice its final concentration) in 1X reaction buffer to all wells using a Multidrop Combi. Plates are incubated at room temperature for 15 minutes. Reactions are initiated by addition of 2.5μL of 2X substrate solution (PIP2 and ATP in 1X reaction buffer) using a Multidrop Combi. Plates are incubated at room temperature for one hour. Reactions are quenched by the addition of 2.5μL of stop solution (Stop A and Stop B pre-mixed at a ratio of 5:1, respectively) to all wells using the Multidrop Combi.The quenched reactions are then processed to detect product formation by adding 2.5μL of Detection Solution to all wells using the Mulitdrop Combi (Detection mix C, Detection mix A, and Detection mix B combined together in an 18:1:1 ratio, i.e.: for a 6000 μL total volume, mix 5400 μL Detection mix C, 300μL Detection mix A, and 300 μL Detection mix B. Note: this solution should be prepared 2 hours prior to use). Following a one hour incubation in the dark, the HTRF signal is measured on the Envision plate reader set for 330 nM excitation and dual emission detection at 620 nM (Eu) and 665 nM (APC).
细胞实验
BT474, HCC1954 and T-47D (human breast) are cultured in RPMI-1640 containing 10% fetal bovine serum at 37 °C in 5% CO2 incubator. Cells are split into T75 flask two to three days prior to assay set up at density which yields approximately 70-80% confluence at time of harvest for assay. Cells are harvested using 0.25% trypsin-EDTA. Cell counts are performed on cell suspension using Trypan Blue exclusion staining. Cells are then plated in 384 well black flat bottom polystyrene in 48 μL of culture media per well at 1,000 cells/well. All plates are placed at 5% CO2, 37 °C overnight and GSK2126458 is added the following day. One plate is treated with CellTiter-Glo for a day 0 (t=0) measurement and read as described below. GSK2126458 is prepared in clear bottom polypropylene 384 well plates with consecutive two fold dilutions. 4 μL of these dilutions are added to 105 μL culture media, after mixing the solution, 2 μL of these dilutions are added into each well of the cell plates. The final concentration of DMSO in all wells is 0.15%. Cells are incubated at 37 °C, 5% CO2 for 72 hours. Following 72 hours of incubation with GSK2126458 each plate is developed and read. CellTiter-Glo reagent is added to assay plates using a volume equivalent to the cell culture volume in the wells. Plates are shaken for approximately two minutes and incubated at room temperature for approximately 30 minutes and chemiluminescent signal is read on the Analyst GT reader. Results are expressed as a percent of the t=0 and plotted against the GSK2126458 concentration. Cell growth inhibition is determined for GSK2126458 by fitting the dose response with a 4 or 6 parameter curve fit using XLfit software and determining the concentration that inhibits 50% of the cell growth (gIC50) with the Y min as the t=0 and Y max as the DMSO control. Value from wells with no cells is subtracted from all samples for background correction.(Only for Reference)
