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.

Ammonium Chloride Solution

Supplier: Stemcell Technologies

Ammonium chloride solution is recommended for the lysis of red blood cells (RBCs) in preparations of human and mouse peripheral blood, spleen or bone marrow cells. It is buffered and optimised for gentle lysis of erythrocytes, with minimal effect on leukocytes. It does not contain a fixative agent, therefore leukocytes are viable following RBC lysis.
