Amersham Hyperfilm Blue is a blue sensitive film for the detection of chemiluminescent signals in different blotting assays. It requires minimal exposure time and yet produces radiographs with sharp and high contrast. The sensitivity of a blue film is lower than that of Amersham Hyperfilm ECL but it is often adequate for many screening applications where qualitative and fast results are required. Amersham Hyperfilm Blue is suitable for use with all blue and green light chemiluminescent systems, such as Amersham ECL and Amersham ECLPrime
