Subsamples can be obtained (1) from a homogenous sample (e.g. cell suspension, tissue homogenate, isolated mitochondria), (2) as subsamples obtained by splitting a sample into comparable parts (e.g. permeabilized muscle fibres from a biopsy split into different chambers for repeated measurements), or (3) repetitive sampling (e.g. taking multiple biopsies) at a single time point. Subsamples may be used for (i) application of different types of assay (e.g. for measurement of respiration and enzyme activities), and (ii) a number of repetitions, n, of the same assay on the same sample.
