Powering your success with our guarantee
Develop your mAb, bispecific, or Fc-fusion protein Research Cell Bank (RCB) with us, either as a standalone RCB or as part of an integrated DNA to IND program, utilizing our proven GS Gene Expression System®, and we guarantee that if your RCB does not achieve:
- ≥ 5 g/L titer1
- A stable cell line (as demonstrated by a stability study conducted by Lonza)2,
…the RCB services and GS Gene Expression System® licensing fees are free.*

*Terms and conditions apply
1For the highest expressing clone at Ambr15 stage, provided that, for DNA to IND programs Lonza has successfully performed an in silico manufacturability stage, and for standalone RCB customers Lonza has carried out an in silico manufacturability assessment and small-scale expression, and in each case Lonza is satisfied with the results and confirms in writing that it is willing to accept the molecule for this RCB offer.
2Based on the lead clone selected at the RCB stage with stability as demonstrated by < 30% change in titer, growth or specific productivity over the length of the study (19 subcultures).
