Abstract
We report the development of a microspectrophotometer system for use on micro samples of mitochondrial respiratory pigments. A novel optical fibre set-up uses visible spectrophotometry to monitor the reduction of mitochondrial electron carriers. Data is presented for the reduction of cytochrome-c and for the effect of temperature on the levels of complex II/III activity from the mitochondria of rat liver. This in-vivo simulation of the reduction of cytochrome-c can be observed using a fibre optic probe which requires less than twenty μl of sample for analysis. The key features of the, system are; front end adaptability, high sensitivity and fast multispectral acquisition which are essential for the biological reactions which are observed.
