Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Tris-Glycine gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) 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 (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) 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. Do not use Tris-Glycine running buffer for Q-PAGE™ Bis-Tris Precast Gels. 4. Rinse the wells before sample loading.
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. (BioRad Mini-PROTEAN® Core Electrophoresis System 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.
| 130 V | 180 V | 230 V*2 |
Running Time*1 | 45-60 mins | 25-40 mins | 15-30 mins |
Expected Current Initial (per gel) Final (per gel) |
60-70 mA 20-25 mA |
100-110 mA 40-50 mA |
130-140 mA 60-70 mA |
Expected temperature | 25-30°C | 25-35 °C | 35-45°C |
*1 Set voltage higher than 100 V is recommended.
*2 For higher voltage conditions, please use fresh running buffer for inner and outer chambers.
*3 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 two plates apart from the top of cassette.
4.Carefully detach the gel either from the bottom of gel or the top side of the cassette.
-Avoid diagonally peeling the gel from the corner.
-Use water to help gel detachment if it needed
5.Gently remove the gel for further staining or Western blotting.

Western、IP 等。主要成分为50mM Tris (pH7.4)，150mM NaCl，1% NP-40， 0.1% SDS。
使用本品裂解得到的蛋白样品，可以用BCA 蛋白浓度测定试剂盒测定蛋白浓度。由于含有
较高浓度的去垢剂，不能用Bradford 法测定由本裂解液裂解得到样品的蛋白浓度。
保存条件：4℃
制备细胞裂解产物：
1、800g 4℃离心5 分钟，收集细胞，估计细胞离心后的体积(PCV,106 cells ≈ 20ul PCV,
107 cells ≈ 100 ul PCV)
2、每50~100ul PCV 加入5 倍体积的蛋白裂解液（250~500ul）,冰浴中放置10 分钟，且每隔5
分钟在漩涡混合仪震荡30 秒；
3、12000g 4℃离心10 分钟，将上清转移到新的离心管中，即得细胞总蛋白产物；
4、假如所得蛋白产物较为粘稠，可95℃加热5 分钟，然后迅速冰浴5 分钟，12000g 4℃离心
10 分钟，将上清转移到新的离心管中，即得细胞总蛋白产物。
制备组织裂解产物：
1、取50-100mg 组织在冰上剪成碎片，用预冷的PBS 洗涤2 次，离心弃去PBS；
2、加入0.5-1ml 预冷的蛋白裂解液；
3、4℃用玻璃匀浆器匀浆20-40 次，直到95%的细胞被破碎，然后在冰浴中放置10 分钟，且每
隔5 分钟在漩涡混合仪震荡30 秒；
4、12000g 4℃离心10 分钟，将上清转移到新的离心管中，即得组织总蛋白产物；
5、假如所得蛋白产物较为粘稠，可95℃加热5 分钟，然后迅速冰浴5 分钟，12000g 4℃离心
10 分钟，将上清转移到新的离心管中，即得组织总蛋白产物。
6、20%的甘油保存于-70℃或-20℃。
常规的96孔板振荡器是作平面圆周运转的
要作PCR板离心漩涡振荡的话，转速建议不要低于2800rpm的。
如果你们现有的振荡器达不到条件的话，建议选和我们一样的仪器，我们选用时是德谱仪器给我们推荐的，他们家好像有多款可选的。
望采纳哦
2.溶氧，在好氧培养过程中，空气是滤过开放的，所以通过摇到可以让更多空气中氧气溶解于发酵液中。
厌氧则不是这个作用了。
3.体系均一，有便于对不同参数的取样测定。
1－5号蛋白浓度分别是（ug/ul）：0.71.12.11.64.8
1－3号为一种细胞，4和5号为LO2细胞
1－4号采用同一种方法提取蛋白，5号采用的是另一种方法
问题：4号比5号的蛋白浓度高很多，但是条带还没没5号的明显？？
4号和5号为什么会有拖尾尤其是4号，而1－3号则是条带太少（只有3条）
2、筛框：由松木或变形量。
推荐一个给你吧《比朗商城》
百度搜索一下！ 服务不错的！
前几天我在稀释引物时，被老师看到我正在用漩涡振荡器震荡稀释过的100uM的引物，老师说不能强烈震荡，容易把DNA振断，那请问大家该用什么方法充分混匀？
另有一个问题：2OD的引物，是（1）全部稀释成5uM后4度保存还是（2）稀释成100uM先保存，等到用的时候再稀释成5uM？哪个更好？谢谢大家
