Gum dyeing method (front dyeing method) (used in the same way as EB)
1. Prepare the agarose gel as usual, add concentrated 10000X Gsafe Red Plus to make the final concentration in the gel 1X Gsafe Red (for example, prepare 100ml gel, add dye 5μl-10μl, the dosage can be adjusted according to the actual situation) , Shake gently and pour the glue.
2. Because it is very sensitive, the amount of DNA marker loading in the electrophoresis process only needs 1-2ul instead of 5ul in EB electrophoresis. Please strictly control the amount of DNA marker loading.
3. Electrophoresis according to conventional methods and observe the results.
Bubble dyeing method (post dyeing method, the specific method is shown on the back)
1. Perform electrophoresis in accordance with conventional methods.
2. Dilute 10000X Gsafe Red Plus concentrate with dH2O about 3300 times to 0.1M NaCl to make 3X staining solution. (For example, add 15μl of 10000X Gsafe Red Plus concentrate and 5ml of 1M NaCl to 45ml of dH2O).
3. Carefully place the gel in a suitable container and slowly add enough 3X staining solution to submerge the gel. Shake at room temperature for about 10-30 minutes. The optimal staining time varies slightly depending on the thickness of the gel and the concentration of agarose. For 3.5-10% acrylamide glue, the dyeing time is usually between 30min and 1 hour. Then observe the results.

Appendix: Standard operating procedures for post-dyeing gum
After the nucleic acid electrophoresis, the stained gel is more and more accepted and adopted by the laboratory because the pollution area is small and the pollution operation is controllable.
Standard operating procedure (take 100ml 1% agarose as an example):
1. Weigh 1g agarose, measure 100ml 1xTAE (or 1x TBE) electrophoresis buffer, and pour into a triangular flask in turn.
2. Boiling the gelatin in the microwave oven causes the agarose to completely melt.
3. Take it out and let it stand for 5 minutes. After the temperature of the glue drops to 50 degrees, pour the glue into the mold.
4. After 20 minutes, when the glue is completely formed, take it out and put it into the electrophoresis tank.
5. Mix PCR products or other DNA samples with the loading buffer and load one by one.
6. Electrophoresis for 20-30 minutes. According to the position of bromophenol blue, determine the appropriate time for electrophoresis and stop electrophoresis.
7. Put the gel after the electrophoresis into the liquid containing the dye, and dye the gel for 10 minutes (if the gel thickness is extended for a reasonable period of time).
8. Take out the glue and put it into the glue scanner to observe the result.

Dyeing liquid configuration: 180ml dH2O, add 20ml 1M NaCl, and then add 10000x Gsafe Red Plus concentrated liquid 60ul.
Use of glue solution: The configured glue solution can be reused many times until the glue strength is very low and then reconfigured.


Gsafe Red Plus Nucleic Acid Dye (10000X) is a red fluorescent nucleic acid stain that has been optimized and developed on the basis of Gelred with gel staining characteristics and is designed to replace the highly toxic staining agent ethidium bromide (EB) with higher clarity and sensitivity. Because Gsafe Red Plus has the same spectral characteristics as EB, it can be used to replace EB without changing any imaging system. If you use SYBR (such as SYBR Green I / SYBR Gold) stain and use a UV transilluminator to observe the gel, you can use Gelred Plus to replace the SYBR stain, without replacing the existing SYBR light. sheet. However, Plus cannot be sufficiently excited under a 488 nm laser or similar visible light. If necessary, it is recommended that you use Gsafe Green stain. Its sensitivity is the same as SYBR Green I, but its stability and reliability are far better than the latter. Plus can be used for both precast gel staining and post gel staining. Generally, post-staining can obtain more sensitive characteristics than pre-staining, and can exclude the possibility that the staining agent will have any effect on the separation of nucleic acid bands during the electrophoresis process. However, front dyeing is simpler and more economical than back dyeing because front dyeing does not require an additional coloring process and the amount of dye used is less. In addition, like GelGreen and EvaGreen, Plus has extremely low ability to induce mutations compared to EB or SYBR. Gsafe Red Plus nucleic acid dye, 10,000X in water is concentrated Gsafe Red Plus solution. When used for pre-dyeing, it can be diluted 10,000 times before use; when used for post-dyeing, it is recommended that you dilute it 3,300 times before use, see specific steps.

Gsafe Red Plus Nucleic Acid Dye (10000X)是在具有凝胶染色特性的Gelred基础上优化开发的红色荧光核酸染料,旨在替代剧毒染色剂溴化乙锭(EB),具有更高的清晰度和灵敏度。由于Gsafe Red Plus具有与EB相同的光谱特性,无需改变任何成像系统即可用于替代EB。如果您使用SYBR(如SYBR Green I / SYBR Gold)染色剂并使用紫外透照仪观察凝胶,您可以使用Gelred Plus代替SYBR染色剂,无需更换现有的SYBR光片。然而,Plus 在 488 nm 激光或类似的可见光下不能被充分激发。如有必要,建议您使用 Gsafe Green 染料。其灵敏度与SYBR Green I相同,但其稳定性和可靠性远优于后者。Plus 可用于预制凝胶染色和凝胶后染色。一般来说,后染可以获得比前染更灵敏的特性,并且可以排除染色剂在电泳过程中对核酸条带分离产生任何影响的可能性。但前染比后染更简单、更经济,因为前染不需要额外的染色工序,染料用量也较少。此外,与 GelGreen 和 EvaGreen 一样,Plus 与 EB 或 SYBR 相比,诱导突变的能力极低。Gsafe Red Plus 核酸染料,10,000X 水溶液是浓缩的 Gsafe Red Plus 溶液。用于预染时,可稀释10000倍后使用;用于后染时,建议在使用前稀释3300倍,见具体步骤。


应用&特点1.Safe and non-toxic: The unique oily macromolecule characteristics make it unable to penetrate the cell membrane and enter the cell. The Ames test result also shows that the mutagenicity of the dye is far less than EB.
2.High sensitivity: It is suitable for electrophoretic staining of fragments of various sizes and has little effect on nucleic acid migration. The sample has a strong fluorescence signal and a low background signal.
3.High stability: It is suitable for preparing agarose gel using microwave or other heating methods; it is extremely stable in acid or alkali buffer at room temperature and has strong light resistance. And not volatile!
4.Simple operation: it does not degrade during precast gel and electrophoresis, and can be directly observed with visible light gel transmission instrument.
