0.1 M Glycine-HCl Elution Buffer Calculator
Scale a 0.1 M glycine-HCl antibody elution buffer at pH 2.7 with experimental HCl adjustment.
Select a reviewed preset and enter the final volume to prepare.
| Reagent | Formula | Amount or action |
|---|---|---|
| Glycinefree compound | 7.507 g | |
| Hydrochloric acid | Adjust experimentally to pH 2.7. | |
| Purified water | After pH adjustment, bring the total solution volume to 1 L. Do not add 1 L of water; add water only until the total solution reaches 1 L. |
How to prepare 0.1 M Glycine-HCl pH 2.7
- Add the calculated glycine to approximately 70–80% of the selected final volume of purified water.
- Stir until the glycine dissolves completely.
- Add HCl gradually while monitoring the pH until pH 2.7 is reached.
- Bring to the selected final volume, mix thoroughly, and verify the final pH. Follow the relevant purification protocol for eluate neutralization.
About This Buffer
Low-pH glycine-HCl buffer is commonly used for elution from Protein A- or Protein G-based affinity media, although the appropriate elution conditions depend on the resin and purification protocol. Because low-pH exposure can affect proteins, neutralization and downstream handling should follow the relevant method. This page scales a fixed 0.1 M glycine-HCl formulation adjusted experimentally to pH 2.7 with HCl.
Common questions
Why is the HCl volume not calculated?
The HCl amount must be determined experimentally from the measured pH and the acid concentration used.
What concentration and pH does this preset produce?
The reviewed preset is 0.1 M glycine-HCl at pH 2.7.
Does the calculator specify how to neutralize the eluate?
No. Neutralization depends on the validated antibody or protein protocol and should not be generalized from the buffer recipe alone.
