L-Arginine 1 M, pH 7.0
1 M L-arginine at pH 7.0 for viscosity and aggregation control in high-concentration formulation. · GMP catalogue product · CT-69520
L-Arginine 1 M, pH 7.0 is a defined arginine concentrate for downstream processing and formulation. It controls viscosity and aggregation in high-concentration antibody formulations and serves as an elution and refolding additive - used mainly in antibody and cell & gene therapy workflows.
Why
- Aggregation control - reduces aggregation in high-conc. formulation.
- Viscosity reduction - for high-concentration products.
- GMP grade - for regulated processing.
- Multi-application - mAb and C&G.
