Description
Histidine Buffered Saline (HBS) 20mL | Pharmaceutical Formulation Buffer
Histidine Buffered Saline (HBS) is a specialised pharmaceutical formulation buffer widely used in biologic drug development, particularly for subcutaneous injection formulations and lyophilised protein reconstitution. Histidine provides superior buffering capacity at slightly acidic pH (6.0) compared to phosphate buffers, while offering additional cryoprotection and anti-aggregation benefits for sensitive peptide and protein research materials.
Research Applications
- Biologic formulation research — the preferred buffer for monoclonal antibody, peptide, and protein SC formulation studies due to pH stability and low ionic strength
- Lyophilised protein reconstitution — maintains peptide structural integrity during reconstitution better than PBS for hydrophobic or aggregation-prone compounds
- Cryoprotection — histidine provides protein stabilisation against freeze-thaw stress in storage studies
- GLP-1 and metabolic peptide research — used for reconstituting GLP-1 analogues (semaglutide, tirzepatide, retatrutide formulation studies)

Dr. L. Whitmore –
Histidine-Buffered Saline used in our lyophilized peptide reconstitution and stability studies. pH confirmed at 6.0. The histidine buffering capacity is superior to PBS for certain peptide formulations. Good quality.
C. Andersen –
HBS is the preferred vehicle for several of our peptide formulations. Rainbow Peptide’s lot confirmed at the correct pH and histidine concentration. Sterile and endotoxin-tested. Convenient to bundle with peptide orders.
O. Nwosu –
Good HBS for peptide reconstitution research. pH within spec. Sterile packaging intact. The histidine buffer protects pH-sensitive peptides better than standard saline. Will include in future orders.
