We studied the performance of“Ready Cap”solid scintillator developed for the liquid scintillation counter, by using 45Ca which is usually employed to deduce intracellular signaling by the tracer method. The liquid scintillators“AQUASOL-2”and“ATOMLIGHT”were used for comparison. Our findings were as follows: (1) A high counting efficiency of over 90% was achieved with the wide range of 200 to 106 dpm, (2) measurement errors due to the uneven resolution of the solid scintillator and/or due to contents such as biological high polymers causing a hindrance in scintillation process were revealed to be low at below 5.3%, and (3) minimal effects were observed on (1) and (2) above even when actual samples containing biological high polymers and cell extracts with biopolymers detergent agent were used. We conclude that the solid scintillator studied here is practically enough useful for liquid scintillation measurement required in biological experiments.
