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.

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. 

 

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.          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™ Mini Precast Gel to BioRad Mini-PROTEAN® Core 1. After removing comb and tape, place the Q-PAGE™ Mini Precast Gel with notched plate facing toward inner chamber.  2. Align the notched plate to ensure the edge sits just below the notch at the top of green gasket.  3. Gently press gel cassette toward green gasket and then lock gel cassette with two green arms. Avoid squeezing the cassette and gel. 
4. Fill inner chamber with running buffer to check tightness of seal. If necessary, reassemble and check the seal again. 5. Fill inner chamber with running buffer to ensure gel wells are completely covered. 6. Fill outer chamber with running buffer to the highest level. 
Adapting Q-PAGE™ Mini Precast Gels to other electrophoresis system, please follow the manufacturer’s instruction.

Troubleshooting Guidelines

Problem

Possible Cause

Suggested Solution

Well deformation

Pull one side of comb out of cassette.

Smoothly pull the comb straight out of the cassette.

Bubbles between gel and cassette

Gel has been frozen or stored at wrong temperature.

Store Q-PAGE Precast Gels at 4°C.

Buffer leaking from the inner chamber

Untight assembly of gels to the electrode modules

Reassemble Q-PAGE gels into the electrodemodules.

Fill outer chamber with 1X running buffer to thehighest level.

Samples do not sink into the wells.

Residual gel storage buffer in the wells

Rinse the gel wells with ddH2O or 1X running bufferbefore loading.

Insufficient sample buffer

Use more sample buffer to prepare samples.

Current is zero and sample do not migrate into gel

Tape at bottom of gel not removed

Remove tape

Gels run faster or more slowly than expected.

Incorrect running buffer

Check buffer composition.

Use fresh 1X running buffer for inner chamber.

Crooked bands at middle or bottom of gel

Gel has been frozen or stored at wrong temperature.

Store Q-PAGE Precast Gels at 4°C.

Incorrect running buffer

Check buffer composition.

Use fresh 1X running buffer for inner chamber.

Band pattern curves toward one or both sides of gel.

Buffer leaking from the inner chamber

Check assembly of gels into the electrode modules.

Excessive heating of gel

Check buffer composition. Or dilute running bufferto 0.5-0.75X.

Do not exceed recommended running conditions.

Insufficient buffer in inner or outer buffer chamber

Fill inner and outer chambers to completely covergel wells.

Poor resolution or fuzzy bands

Excessive heating of gel

Check buffer composition.

Do not exceed recommended running conditions.

Incorrect running buffer

Check buffer composition.

Bands are missing on the membrane after Westerntransferring.

Proteins move in the wrong direction

Check the order of gel/membrane sandwich assembly,the direction of transfer cassette in transfer modules, and the polarity ofconnections to power supply.

Swirls or missing bands; bands trail off in multipledirections on the membrane after Western transferring.

Contact between the membrane and the gel was poor;Air bubbles or excess buffer remains between the blotting membrane andthe gel. 

Use thicker/more filter paper in the gel/membranesandwich

Remove air bubbles and excess buffer betweengel and membrane by carefully moving the roller over the membrane.

Apparent molecular sizes of prestained proteinmarkers are different as indicated.

Prestained protein markers used have not beencalibrated for use with Q-PAGE gels. Dyes for staining protein markers affect themigration patterns of prestained proteins in different buffer systems.

Calibrate prestained protein markers againstunstained proteins of known size or use SMOBIO’s ExcelBand™ Protein Markers.

四甲基罗丹明可以用于活体成像
丙酮法属于溶液法,是以有机溶剂稀释或溶解聚氨酯(或预聚体),再进行乳化的方法。在溶剂存在下,预聚体与亲水性扩链剂进行扩链反应,生成较高分子量的聚氨酯,反应过程可根据需要加人溶剂以降低聚氨酯溶液粘度,使之易于搅拌,然后加水进行分散,形成乳液,最后蒸去溶剂。溶剂以丙酮、甲乙酮居多,故称为丙酮法。此法的优点是丙酮、甲乙酮的沸点低、与水互容、易于回收处理,整个体系均匀,操作方便,由于降低粘度同时也降低了浓度,有利于在乳化之前制得高分子量的预聚体或聚氨酯树脂,所得乳液的膜性能比单纯预聚体法的好。而预聚体法由于粘度的限制,为了便于剪切分散,预聚体的分子量不能太高,可能会影响水性聚氨酯性能,例如粘度高则乳化困难,粒径大,乳液稳定性差;预聚体分子量小则NCO基团含量高,乳化后形成的脲键多,胶膜硬,缺乏柔软性。

请问各位,我想做荧光标记的蛋白在活体显像的实验,需要invivoimagingsystem,中文应该是荧光蛋白活体成像系统,有做过的吗放射深度是多少呀必须用小鼠做吗可以定量分析吗
我实验急需活体荧光蛋白成像系统,请问国内哪里有啊,成都有吗,谢谢
