What reagent grades, purity labels and specifications mean: ACS/AR, HPLC, electronic grade and tag-grade proteins, in 190+ guides from Aladdin Scientific.
DNase, RNase, and Protease-free grade reagents are essential for applications requiring high integrity of DNA, RNA, and proteins. These reagents are specially prepared and tested to ensure they do not introduce nucleases or proteases that would degrade biological macromolecules.
DNase/RNase-Free grade reagents are specially prepared and quality-controlled chemical or biological substances that are free of deoxyribonuclease (DNase) and ribonuclease (RNase) enzyme contamination.
DNase Free grade refers to biological reagents that have been verified to be free of deoxyribonuclease (DNase) enzymes. DNases degrade DNA by cleaving the phosphodiester bonds between nucleotides.
