Abstract
Methods and apparatus are disclosed for correcting measurements received by applying a frequency-varying signal with a measuring device (e.g., a permittivity probe) to a population of living cells (e.g., contained in a bioreactor) and correcting measurement divergences using data acquired using an alternate analytical method (e.g., trypan blue exclusion). In one example, a method comprises receiving electrical property data for a first population of cells, the data obtained by applying a first frequency-varying signal to the population with a measuring device, receiving biological property data obtained using an alternate analytical technique, generating at least one value representative of the frequency dependence of the electrical property data, and determining a relationship between the biological property data and the representative value. In some examples, measurements of apoptosis are predicted using the electrical property data.
