extendSURE™ Controls have Exceptional Stability

The stability of a quality control product is an important issue. A good control should continue to give the same result on repeated analysis during the defined life of the control. The control must be stable not only during its life in the diagnostic laboratory but during transportation from the manufacturer or distributor to the laboratory.

Degradation of protein occurs as a result of chemical and free radical reactions. The integrity of the control can be damaged as a result of a poorly designed lyophilization protocol, or by repeated freezing and thawing, or as a result of microbial growth. It is important during the design of a control that unwanted reactions and conditions are identified and the production and formulation of the controls is planned so that these reactions are inhibited or their rates dramatically reduced. It is also important that any protective additives do not interfere with the analytical methods.

The extendSURE™ controls have been carefully formulated to include a number of protectants and stabilizers that preserves the proteins in their native conformation. This results in products with exceptional stability.
