Gold Biotechnology Inc Tris (Tris Base) 1 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.
Gold Biotechnology Inc Timentin™ Ticarcillin/Clavulanate (15/1) 25 g
Timentin™ is a 15:1 mixture of ticarcillin and clavulanate. Ticarcillin is a penicillin ß-lactam antibiotic, which is susceptible to ß-lactamase degradation. When combined with clavulanate, a ß-lactamase inhibitor, its efficacy is greatly increased. Timentin™ exhibits high activity against gram-negative bacteria and resistant Agrobacterium species.
