Buffer screening applications
Buffer screening made easy: The 2bind FDA-plate® provides 96 pre-made buffer conditions from approved Formulations of Developed Antibodies.
All buffers were designed by antibody formulation experts and have already proven to be beneficial for stability and storage of therapeutic antibodies. Each buffer has been approved by FDA or EMA for use in antibody formulations.
Use the FDA-plate® for buffer screening, analysis of protein and antibody stability, buffer optimization, and (pre-) formulation development. Or use the plate to determine important parameters for regulatory approval of your antibodies like colloidal stability, thermal stability, freeze-thaw resistance, chemical stability, or long-term and forced degradation behavior.
Identify optimal conditions for antibody and protein stability by simple and quick buffer screening. Thermal and chemical stability, long-term storage, forced-degradation, and (pre-)formulation.
Apply the FDA-plate buffer screening quickly and easily to your methods of choice (e.g. DSF, nanoDSF, DSC, DLS, LC-MS, SEC-HPLC, ELISA).
The FDA-plate buffer screening is the optimal starting point for pre-formulation development and buffer optimization of antibodies and other proteins.
• 96 conditions from FDA- and EMA-approved formulations of therapeutic antibodies
• Ready-to-use 5x buffer screening stock solutions (0.2 mL)
• Wide range of different buffer compositions:
pH: 4.6 – 8.0 (acetate, citrate, glycine, histidine, phosphate)
Salts: 3 – 200 mM (potassium chloride, sodium chloride)
Amino acids: 1 – 300 mM (glycine, glutamate, methionine, proline)
Sugars: 12 – 300 mM (maltose, mannitol, sorbitol, sucrose, trehalose)
Detergents: 0 – 1.6% (polysorbate 20, polysorbate 80)
No need to prepare buffers. Just dilute your sample of choice into the pre-made buffers and you are ready to go for buffer screening.
No need to buy small quantities of expensive buffer substances. Cut analysis costs by saving hands-on-time in the lab.
All buffers are made to highest quality standards and are tested with reference antibodies. Each buffer is also available as a re-fill stock for additional buffer screening.
