Can the samples on the TissueLyser LT be protected from degradation of nucleic acids or proteins?

Yes, if using fresh samples that are not stabilized with a stabilization reagent (e.g., RNAprotect Tissue Reagent or Allprotect Tissue Reagent) the TissueLyser LT Adapter can be precooled on dry ice. During the disruption process the adapter will passively cool the samples to prevent heating and degradation of nucleic acids or proteins.

See:  TissueLyser Virtual Demo for a virtual demonstration of this precooling process with the TissueLyser LT.
