Scaling up the harvest process while preserving what matters

CLS White Paper | Avantor

Improving cell lysis methodology is an impactful and easy-to-adopt unit operation to minimize loss and improve overall process yield. Triton™ X-100 is the industry-favored method of lysis however, new environmental regulations require an alternative reagent selection.
This white paper presents features of a new chemical lysis agent, J.T.Baker® Cell Lysis Solution, which can rapidly rupture cell membranes across a wide range of operating conditions and is compatible with traditional DNA removal agents such as J.T.Baker® Endonuclease.
Study data illustrates this efficacy, as well as additional characteristics of this biodegradable cell lysis agent:

  • Comparable lysis performance to Triton™ X-100 across a range of cell densities, and at standard process temperatures and pH levels, to support flexible process development
  • Protection of viral vectors during lysis comparable to Triton™ X-100
  • Clearance during downstream processing
  • Proven compatibility to standard Endonucleases including J.T.Baker® Endonuclease
