Collection: Biological Buffers

Biological Buffers — covers pH buffering compounds for biological systems, including Good's buffers (cyclic amino sulfonic acid derivatives), tris(hydroxymethyl)aminomethane compounds, glycylglycine, and other buffer-related reagents. This group is designed to maintain solution pH within a specific range during biochemical processes.

Biological buffers are used by biochemistry and molecular biology researchers to keep pH stable in cell cultures, electrophoresis, HPLC chromatography, and in vitro enzymatic reactions. Ready-to-use solution forms (instant buffers) simplify buffer preparation without re-weighing, while tris derivatives are widely used in protein and nucleic acid electrophoresis protocols.

Example products in this collection: TCI C0921 1135-40-6 3-Cyclohexylaminopropanesulfonic Acid [Good's buffer component for biological research], TCI C0920 103-47-9 2-Cyclohexylaminoethanesulfonic Acid [Good's buffer component for biological research], TCI T4022 5204-74-0 Triethylammonium Acetate (20mol/L in Water) [for HPLC], TCI C1562 102601-34-3 3-Cyclohexylamino-2-hydroxypropanesulfonic Acid Sodium Salt, TCI T3294 6850-28-8 Tris(hydroxymethyl)aminomethane Acetate, TCI C2426 73463-39-5 3-(Cyclohexylamino)-2-hydroxypropane-1-sulfonic Acid, TCI T2516 77-86-1 Tris(hydroxymethyl)aminomethane [for Electrophoresis], TCI G0124 556-50-3 Glycylglycine.

Pay attention to the pKa range of buffer compounds to match the working pH, their form (solid or ready-to-use solution), and the purity grade for analytical applications such as HPLC. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
