I have generated a protocol for extracting signal tubular cells form mouse kidneys. The RNA extract is with no protein or phenols contamination and with high concentration. However, the RNA integrity number (RIN) is 6-7.
I have tried washing the Kidneys with RNAlater, but it did not improve the results. I need to achieve a RIN of about 8 in order to do RNA-seq.
I would be happy for suggestions
