RNA extracted from 15 mg rat liver sample using the RNA Easy Fast Tissue/Cell Kit and relevant product from supplier A and T. Elution volume: 100 μl; Loading volume: 3 μl M: TIANGEN Marker D15000 Experiment result: RNA Easy Fast Tissue/Cell Kit has higher extraction rate than the relevant product from supplier A and T. |
A-1 Cell lysis or homogenization not sufficient
---- Reduce sample usage, increase the amount of lysis buffer, increase homogenization and lysis time.
A-2 Sample amount is too large
---- Reduce the amount of sample used or increase the amount of lysis buffer.
A-1 Insufficient cell lysis or homogenization
---- Reduce sample usage, increase the amount of lysis buffer, increase homogenization and lysis time.
A-2 Sample amount is too large
----Please refer to the maximum processing capacity.
A-3 RNA is not eluted completely from the column
---- After adding RNase-Free water, leave it for a few minutes before centrifuging.
A-4 Ethanol in the eluent
---- After rinsing, centrifuge again and remove the washing buffer as much as possible.
A-5 Cell culture medium is not completely removed
---- When collecting cells, please make sure to remove the culture medium as much as possible.
A-6 The cells stored in RNAstore are not effectively centrifuged
----RNAstore density is greater than the average cell culture medium; so the centrifugal force should be increased. It is suggested to centrifuge at 3000x g.
A-7 Low RNA content and abundance in the sample
---- Use a positive sample to determine if the low-yield is caused by the sample.
A-1 The material is not fresh
---- Fresh tissues should be stored in liquid nitrogen immediately or immediately put into the RNAstore reagent to ensure the extraction effect.
A-2 Sample amount is too large
---- Reduce sample amount.
A-3 RNase contamination
----Although the buffer provided in the kit does not contain RNase, it is easy to contaminate RNase during extraction process and should be handled with care.
A-4 Electrophoresis pollution
---- Replace the electrophoresis buffer and make sure the consumables and Loading Buffer are free of RNase contamination.
A-5 Too much loading for electrophoresis
---- Reduce the amount of sample loading, the loading of each well should not exceed 2 μg.
A-1 Sample amount is too large
---- Reduce sample amount.
A-2 Some samples have high DNA content and can be treated with DNase.
----Perform RNase-Free DNase treatment to the obtained RNA solution, and the RNA can be directly used for subsequent experiments after treatment, or can be further purified by RNA purification kits.
For glasswares, baked at 150°C for 4 h. For plastic containers, immersed in 0.5 M NaOH for 10 min, then thoroughly rinsed with RNase-free water and then sterilize to completely remove RNase. The reagents or solutions used in the experiment, especially water, must be free of RNase. Use RNase-free water for all reagent preparations (add water to a clean glass bottle, add DEPC to a final concentration of 0.1% (V/V), shake overnight and autoclave).
