We have developed procedures that combine differential centrifugation and discontinuous Percoll density gradient centrifugation to isolate mitochondria from rat forebrains and brain subregions. The ...

IN several laboratories, where whole lipid extracts are chromatographed on silicic acid in chloroform-methanol, experience has suggested the need for continuous concave gradient elution. Devices are ...

In this paper, we propose a new unbiased stochastic derivative estimator in a framework that can handle discontinuous sample performances with structural parameters. This work extends the three most ...
