WebCell lysis buffer for RNA extraction is highly denaturing and is usually composed of phenol and guanidine isothiocyanate. RNase inhibitors are usually present in the lysis buffer, since RNases can be very resistant to denaturation and remain active. For extraction of DNA the lysis buffer will commonly contain SDS. WebThe buffer saturated phenol may be stored at 4°C for 1 month for DNA extraction. Test the pH periodically and do not use if the pH is <7.5 Note: Phenol will be lost during the preparation of the buffer saturated phenol.
