1. A in a higher volume of Elution Solution A will result in diluting your RNA 8 What if I forgot to do a dry spin after my third wash e Your RNA elution will be contaminated with traces of the Wash Solution A This may dilute the RNA yield in elution Also it may interfere with your downstream applications Re isolate the eluted RNA using the same procedure as you initially isolated the RNA from urine but using your elution as your input 9 Why did my samples show very low RNA yields e Some urine samples contain very little RNA This varies from individual to individual based on numerous variables In order to increase the yield the amount of urine input could be increased 10 Why does my RNA not perform well in downstream applications e lf a different Elution solution was used other than the one provided in the kit the buffer should be checked for any components that may interfere with the application Common components that are known to interfere are high salts including EDTA detergents and other denaturants Check the compatibility of your elution buffer with the intended use 11 What is the expected RNA yield from urine e Normally the urinary RNA yield varies between individual samples depending on a number of factors such as time of sample collection age sex diet etc Sometimes the RNA yields from urine are too low to be visualized on an agarose gel or to be quantified by regular spectrophotometric methods however the R2.
