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.

Hanks' Balanced Salt Solution, Modified without Ca++ and Mg++

Supplier: Stemcell Technologies

Hanks’ Balanced Salt Solution (HBSS) can be used for diluting, washing, irrigating or as a transporting solution for cell or tissue culture. It provides a buffering system to maintain the physiological pH range and osmotic balance of culture media, and provides cells with a source of water and essential inorganic ions and a carbohydrate as an energy source. Selection of suitable nutrient medium is dependent on type of cell, culture conditions, and degree of chemical definition required for the cell culture application.
