Description
Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses.
Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 12- and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

Recommendations/Tips for Gel Running
1. Remove comb and tape before adaption. 2. Use fresh 1X running buffer for the inner cathode chamber. 3. Rinse the wells before sample loading. 4. Try 200 V first, and optimize the voltage and running time if needed. Do not set voltage lower than 100 V.
Sample Preparation for SDS-PAGE
1. Mix protein sample with 2X sample buffer.
2. Heat the diluted samples at 95°C for 5 min or at 70°C for 10 min.
3. Cool the diluted samples to 4°C and spin down the water condensed on tube surface. (If there is high viscosity part at bottom of tube, transfer supernatant to a new tube.)
Prepare Q-PAGE™ for Sample Loading
1.Open the blister tray of Q-PAGE™ Precast Gel.
2.Briefly rinse the gel cassette with ddH2O.
3.Remove tape and comb; avoid squeezing the gel.
4.Adapt Q-PAGE™ to electrophoresis system; instruction are provided below. (Invitrogen® Mini Gel Tank is recommended.)
5.Use a pipette to gently wash the wells with running buffer to remove residual storage buffer.
6.Fill the wells with running buffer prior to sample loading.
7.Load samples and pre-stained protein marker into numbered wells.
8.Fill both inner and outer chambers with running buffer to the highest level. Ensure gel wells are completely covered.
Power Setting for Running Q-PAGE™
Optimize the voltage and running time if needed.

35-45 mA 10-20 mA |
45-55 mA 20-25 mA |
75-85 mA 40-45 mA |
100-110 mA 60-70 mA |
Expected temperature | 25-30°C | 25-30 °C | 25-35°C | 30-40°C |
*1 Set voltage higher than 100 V is recommended.
*2 Try 200 V first, and optimize the voltage and running time if needed
*3 For higher voltage conditions, please use fresh running buffer for inner and outer chambers
*4 Running time varies depending on gel percentage, running buffer, temperature, and power supply.
Remove Q-PAGE™ Gel from Cassette
Open cassette immediately after electrophoresis. Avoid gel drying.
1.Insert the cassette opener into corners of cassette.
2.Sequentially pry the opener to separate the two plates.
3.Gently pull up notched plate and let gel stay on the front plate.
4.Use cassette opener to push through the slot in the cassette.
5.Carefully detach the gel from the bottom of gel.
- Avoid diagonally peeling the gel from the corner.
- If necessary, cut well separators with gel remover.
6.Gently remove the gel for further staining or Western blotting.
Gel Staining
Proteins separated using Q-PAGE™ Precast Gels can be further stained with most popular staining reagents, such as Coomassie dyes (R-250 or G-250), Silver-stain solution,
and FluoroStain™ Protein Fluorescent Staining Dye. (Cat. No. PS1000)
Transferring Protein from Q-PAGE™ to Blotting Membrane
1. After protein separation using Q-PAGE™, gently detach QPAGE™ from cassette and then equilibrate the gel in transfer buffer.
2. Pre-soak blotting membrane and filter papers in transfer buffer.
*Activate PVDF membrane in methanol before soaking in transfer buffer.
**Prepare 6 filter papers for one gel/membrane sandwich.
3. Assemble transfer sandwich by orientating cathode, sponge, filter papers, gel, membrane, filter papers, sponge, and anode. The protein goes to the direction of cathode to anode.
4. Carefully move roller over the gel/membrane to remove air bubbles and excess buffer until complete contact is established.
5. Insert transfer cassette into transfer module. Notice that black side of cassette should be next to black side of module.
6. Fill transfer tank with pre-cooled transfer buffer to the highest water level.
7. Set constant voltage at 100 V. Transfer for 90 minutes at low temperature condition. Pre-stained protein marker should be visible on the membrane after transfer is completed.
Transfer of proteins to the membrane can be checked using Ponceau S staining before blocking step.
Supplemental Information for Using Q-PAGE™ Precast Gel
Adapting Q-PAGE™ Midi Precast Gels to Invitrogen Mini Gel Tank Electrophoresis System
1. Place the Q-PAGE Midi Precast Gels with notched plate facing toward yourself. No extra adapter is needed.
2. Seat the gels on the bottom of Mini Gel Tank and close the cassette clamp.
3. Fill chambers with running buffer to the level of the fill line. Ensure gel wells are completely covered.
Adapting Q-PAGE™ Midi Precast Gels to other electrophoresis system, please follow the manufacturer’s instruction.

菜鸟求救，大虾帮忙看看，感激不尽。
总体上来说，在纯水仪器上，进口品牌中密理博、pall、威立雅都算是国内科研单位采购比较多的，当然，售价也较高，一般为国产品牌的3-5倍，除非硬性规定，或者需要用进口高端设备来提升实验室形象，否则，不建议花冤枉钱，因为目前国内很多纯水品牌在技术上都已经追赶甚至超越了进口品牌。
此外，很多人不了解的是，许多欧美品牌的纯水机，虽然技术成熟，但是都是基于国外的水质而研发，而我国自来水水质事实上比欧美国家的低（欧美国家的自来水可直接饮用），因为存在进口品牌的水机在我国水土不服的现象，甚至其前端处理仍需搭配国产设备，只是很多客户并不知晓，尤其是中央供水系统更是如此。这一点需要注意。
国产纯水品牌的话，鱼龙混杂，这里仅仅介绍几个知名度较高，市场做得比较大的，并简单分析对比：
1、锐思捷：在技术上比较成熟，水机的品质和进口品牌做过很多对比和验证，基本上也足以媲美进口品牌了，产品线包含小型机（10-60L）和大型中央供水系统（200L-5T），价格在中高位置；
2、和泰：主做小型机，中央供水系统较少，价格由近万至7万左右，小型机产品线丰富，在市场营销方面下的力度非常大；
3、力康：也算是中高端国产纯水仪器，同时也做其他实验室设备；
此外还有优普、易普易达等区域性品牌。
好？急盼提供建议，多谢多谢！
纯水机，是利用反渗透膜产出纯净水的净水机，属于直饮机。
二者区别：直饮机是一个统称，包含纯水机、超滤直饮机等；纯水机就是生产纯净水的机器，出水可以直接饮用。
RO逆渗透是一种通过目前国际流行的反渗透等办法，对原水进行过滤处理（物理法）后不添加任何化合物而生产出可供人类直接饮用的纯净水机器（也称为终端净水设备）。
采用水质符合中国卫生部《生活饮用水水质卫生规范》（2001）规定的市政自来水为原水，通过2个活性炭滤芯（1个颗粒活性炭、1个烧结活性炭）1个PPF溶喷滤芯对原水进行预过滤，再对预过滤水施加压力令其通过孔径大小为万分之一微米的RO（反渗透，英文Reverse Osmosis）膜，最后通过材质为果壳（椰壳）的载银活性碳（又名小T33）调节水的酸碱度（使制出的纯净水口感变得甘甜醇美）而生产出纯净水。
纯水机的选取首先要看您是做什么用途？不同型号和配置的水机，在各个指标的纯化程度是有倾斜的，这也决定了各型号的水机采取什么核心组件，进而决定价格。例如，如果做的实验室细胞培养类型的，那么就要求有机物、无极离子都要净，价格相对较高；如果是无机分析实验，那么对水中的无机离子去除要求较高，有机物物质相对不那么严格，价格会略低。
同时还取决于设备的产量等因素。
进口的密理博、pall，价格都在5万以上，甚至十多万；国产的比较杂，近万到数万元不等。
国产中锐思捷技术比较好，价格在3-5万之间，其他的如和泰或者乐枫。
