Tampons

Tampons

Résistant aux variations de pH, les tampons protègent les échantillons lors de l'ajout d'acides ou de bases. Disponibles sous forme de poudre ou de liquide, ils permettent un suivi efficace des protéines pendant l'électrophorèse et leur séparation. Les tampons salins peuvent également servir à calibrer et à standardiser les pH-mètres pour des mesures précises. Les substances bloquantes empêchent la fixation des anticorps aux sites libres de la membrane, évitant ainsi un bruit de fond parasite. Proposés à différentes concentrations pour répondre à tous les besoins, les tampons sont disponibles sous forme liquide ou déshydratée.

10X Phosphate Buffered Saline (PBS), Sterile, Dulbecco's Formula, without Magnesium and Calcium

Supplier: MP Biomedicals

Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions: 1. Serves as an irrigating, transporting and diluting fluid while maintaining intra- and extracellular osmotic balance; 2. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism; 3. Combined with a carbohydrate, such as glucose, provides the principal energy source for cell metabolism; 4. Provides a buffering system to maintain the medium within the physiological pH range (7.2 - 7.6)

ISE sample conditioning buffers and solutions

Supplier: WTW

Ion strength adjustment solutions have multiple tasks: TISAB for fluoride measurements does not only adjust the pH value, by also decomplexes the fluoride-containing complex compounds. Other ion strength adjustment solutions ensure an adapted pH value as well as the addition of a suitable conducting salt to correctly capture the concentration.
