Nuclear Fast Red Solution (Enhanced Stability)

Larger picture

Nuclear Fast Red is a stain with histological applications. The newly formulated reagent has improved stability over current formulations allowing reagent to be stored at room temperature or 2-8° Centigrade. Current formulations tend to precipitate in cold temperatures such as experienced during winter shipping. In addition, most formulations develop a small amount of precipitate over extended periods of time. This new formulation completely eliminates the problems associated with exposure to cold and aging. As with our current formulation (NFR) this reagent is provided as a single component, ready-to-use solution. This product has been optimized to be stored at 2-25° Centigrade.
