Histidine Buffered Saline (HBS) 20mL

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)
