Ammonium sulfate 3 M
High-concentration 3 M ammonium sulfate stock for flexible high-salt loading in HIC. · GMP catalogue product · CT-68500
Ammonium sulfate 3 M is a high-concentration ammonium-sulfate stock for downstream processing. It enables HIC loading at higher salt strengths than the 1 M stock and is used for salt precipitation. As a GMP-grade stock it is applied across monoclonal antibodies, vaccines, mRNA and cell & gene therapy.
One GMP quality. Ammonium sulfate 3 M is a GMP-grade catalogue product (CT-68500), manufactured by PAN-Celltech and released against a defined quality-control panel on every lot.
Why
- Higher salt strength – Flexible HIC loading beyond the 1 M stock.
- Also for precipitation – Salt precipitation / conditioning.
- GMP grade – Catalogue GMP quality, released per lot.
- Multi-application – Used across antibody, vaccine and C&G downstream.
