Sodium citrate (CAS 68-04-2) is a tricarboxylate anion derived from citric acid commonly supplied as a highly water-soluble white crystalline material Functioning as an alkalinizing agent sodium citrate acts by neutralizing hydrogen ions in physiological fluids thereby increasing systemic and urinary pH This buffering action is leveraged in studies of acid-base physiology metabolic acidosis and renal function In biomedical research sodium citrate is also frequently utilized as an anticoagulant in blood specimen preparation and as a component in cell culture systems requiring controlled pH environments
Gold Biotechnology Inc Tris (Tris Base) 5 kg
GoldBio Tris has the highest purity available on the market. Short for Tris (hydroxymethyl) aminomethane (THAM), Tris is an organic compound often used in buffer solutions such as TAE or TBE for electrophoresis gels. Tris is highly soluble in water and is useful in the pH range 7.0-9.0. It is used in the preparation of Laemmli buffer, one of the most common SDS-PAGE buffers. In addition, Tris can also be used for many custom running and loading buffers, most often with glycine and SDS. The use of single-junction pH electrodes that contain silver should be avoided when determining the pH of a solution containing Tris buffer.
