Glycine 100 mM, pH 3.0
Ready-to-use 100 mM glycine buffer at pH 3.0 for low-pH elution and inactivation steps in downstream processing. · GMP catalogue product · CT-69500
Glycine 100 mM, pH 3.0 is a defined, ready-to-use low-pH buffer. In downstream processing it serves mainly as a low-pH elution buffer for affinity (Protein A) capture – an alternative to citrate – and for low-pH hold steps. As a GMP-grade buffer with a fixed composition and pH it is used broadly across biologics platforms, from monoclonal antibodies, vaccines, mRNA and cell & gene therapy.
One GMP quality. Glycine 100 mM, pH 3.0 is a GMP-grade catalogue product (CT-69500), manufactured by PAN-Celltech and released against a defined quality-control panel on every lot.
Why
- Defined low pH – Fixed pH 3.0 ± 0.2 for reproducible elution.
- Alternative to citrate – For Protein A platforms that prefer a glycine system.
- GMP grade – Catalogue GMP quality, released per lot.
- Multi-application – One buffer across antibody, vaccine, mRNA and C&G downstream.

In the process – by application (upstream & downstream)
Glycine 100 mM, pH 3.0 is used at the following process steps across the biologics platforms it supports:
Monoclonal antibodies
- Protein A capture – alternative low-pH elution.
- Viral inactivation – low-pH hold where a glycine system is preferred.
Vaccines
- Affinity / IEX – acidic elution or low-pH hold where used.
Cell & gene therapy
- Affinity capture (AAV / viral vectors) – low-pH elution.
Frequently asked questions
What is Glycine 100 mM Buffer used for?
It is used mainly as a low-pH elution buffer for Protein A affinity capture and for low-pH hold steps in downstream processing.
What is the pH?
It is supplied at a fixed pH of 3.0 ± 0.2.
Can it be used outside antibody processes?
Yes. It is a general low-pH buffer applicable across monoclonal antibodies, vaccines, mRNA and cell & gene therapy downstream, wherever a defined low-pH buffer is required.
