Many radioactive biological samples measured by liquid scintillation counting techniques are not readily soluble in the commonly used solvents of liquid scintillation cocktails. Special solubilizers are required to obtain a homogeneous system for reproducible measurement of the radioactive sample.

In Liquid Scintillation Counting (LSC), preparationof biological samples has always been treated as aspecial case because of the difficulties associated with their preparation for counting. In general, all biological samples contain components not generallyfound in any other sample types, therefore it is of benefit to understand the composition of these samples to fully understand the need for the slightly unusual sample preparation methods.
Filter counting, or solid support counting as it is sometimes known, is probably best described as heterogeneous counting. The main difference between heterogeneous counting and homogeneous countingis that heterogeneous counting relies on 2 p geometry while 4 p geometry applies to homogeneous counting. An explanation of the terms 2 p and 4 p geometry is needed to appreciate the differences between the two counting techniques. I
A researcher had been using PerkinElmer’s Biological Sample Preparation Guide in an attempt to process sheep plasma samples. The samples were labeled with 3H and 14C. The current procedure called for 0.1 mL or 0.2 mL of plasma with 0.5 mL of deionised (DI) water in 15 mL of ULTIMAGold™. After several hours, the samples would turn cloudy and separate. The researcher requested our help to refine her sample preparation technique or recommend conversion to an alternate cocktail.
Difficulties performing the solubilization of hair prompted one researcher to contact our offices for assistance. This laboratory was using PerkinElmer’s Soluene®-350 to solubilize other materials and hoped that it could also be used for their new hair samples.
