Advantages of DNase/RNase-Free Proteinase K Solution

Proteinase K is an enzyme that belongs to the class of serine proteases, characterised by its ability to break down proteins by cleaving the peptide bonds between amino acids. Meanwhile, DNase and RNase are enzymes that degrade DNA and RNA. These enzymes are present in many biological samples and can interfere with the isolation or analysis of nucleic acids.

Therefore, it is important to use solutions that are free of DNase and RNase when working with DNA or RNA. This GERBU Proteinase K solution is DNase/RNase-Free and does not contain any contaminants that could introduce them, ensuring its utmost purity and effectiveness.

Proteinase K Applications

Proteinase K plays a crucial role in DNA and RNA preparation by eliminating natural nucleases from biological samples. It digests protective proteins like histones or ribonucleoproteins and inactivates any remaining DNases or RNases that could degrade nucleic acids during extraction or purification.

The benefits of Proteinase K extend beyond nucleic acid preparation. Its unique ability to permeabilize cell membranes and break down proteins that link DNA or RNA in the tissue. This facilitates the optimal preparation of tissue sections for in situ hybridization. This opens up new possibilities for studying gene expression, localization, and other molecular interactions within the tissue, with precision and accuracy.

Proteinase K is also valuable for studying enzyme cleavage specificity, serving as a reference enzyme to compare the activity and substrate preferences of other proteases.
