Polysorbate 20 (PS20) 1 %
1 % polysorbate 20 surfactant stock to prevent protein aggregation and surface adsorption. · GMP catalogue product · CT-00211
Polysorbate 20 (PS20) 1 % is a defined surfactant stock for downstream processing. Added in UF/DF and final formulation, it protects proteins from aggregation and interface/adsorption stress. As a GMP-grade stock it is applied across monoclonal antibodies, vaccines, mRNA and cell & gene therapy.
Why
- Protects protein at interfaces - Prevents aggregation and adsorption.
- Concentrated 1 % stock - Easy to dose into the formulation.
- GMP grade - Catalogue GMP quality, released per lot.
- Multi-application - Formulation surfactant across platforms.
