Thermo Scientific BupH Carbonate-Bicarbonate Buffer Packs are pouches of dry-blended powder that are each sufficient to make 500 mL of alkaline (pH 9.4) Na-carbonate (carb-bicarb) buffer for use in protein and antibody coating procedures.

BupH Dry-Blend Packs of carbonate-bicarbonate buffer are easy to use. Simply empty contents of one foil envelope pack into a beaker, add ultrapure water and stir to dissolve. The packs eliminate weighing time and tedious pH adjustments. When dissolved in 500 mL of water, each pack makes 0.2M carbonate-bicarbonate, pH 9.4.

Features of BupH Carbonate-Bicarbonate Buffer Packs:

• Carb-bicarb buffer—dissolved in 500 mL of water, each pack makes 0.2M carbonate-bicarbonate, pH 9.4
• Convenient—dissolve contents of one envelope in water and the buffer is ready to use
• Save time and trouble—no weighing, no pH adjustment, no need to stock individual components, and no need to make and store large volumes of stock solution in advance of daily needs
• Long shelf life—stocking and storage as dry packs eliminates concerns about long-term stability of stock solutions
• Eliminate variables—our quality control ensures that every pack will yield the same, consistent buffer

Applications:
• Coating or binding capture-antibodies and other proteins onto polystyrene microplates for ELISA and other plate assays
