It can perform simultaneously integral measurements of chemiluminescence emitted from up to six samples containing less than 0.5 μl whole blood while the samples and detector do not change their position during the measurement cycle. ![]() The optical fibers in this luminometer are used as both light guides and solid phase sample holders. The latter feature of the instrument design simplifies the assessment process of both the extra-cellular and the intra-cellular parts of the phagocyte-emitted chemiluminescence using the same system. We describe some examples or proof of principle for the use of the biosensor.
