What is the composition of Buffer PKD?

The exact composition of Buffer PKD is proprietary. Buffer PKD functions as a Proteinase K Digestion Buffer and is a component of, for example, the AllPrep DNA/RNA FFPE Kit, RNeasy FFPE Kit, and the miRNeasy FFPE Kit. We are sometimes asked if Buffer PKD comprises any RNase inhibitors or RNase inhibiting agents — since the formalin-fixation of the starting material has already inactivated the RNases, no such reagents are present in this buffer.
