Buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

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)

Low pH SDS Sample Buffer

Supplier: EKSIGENT

SCIEX Low pH SDS Sample Buffer, 140 mL (100 mM Tris-HCl, pH 6.8, 1% SDS) allows you to use SCIEX’s Gold Standard CE-SDS with a low pH SDS sample buffer. Use of this buffer can increase non-reduced purity by decreasing method induced fragmentation. Less variability and lower RSDs means less troubleshooting and faster method development.

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.
