Two Quantitative Methods for Imaging Samples in Molecular Biology

open access: closedcclm, 1998
Abstract In this paper, we introduce two autoradiography imaging systems from Packard Instrument Company, that provide unmatched speed, accuracy, sensitivity, and resolving power for radioisotopic imaging in biomedical research. The first system is a direct nuclear imaging system, which provides fast and accurate nuclear counting without

The reproductive biology of the dendrochirote sea cucumberCucumaria frondosa(Echinodermata: Holothuriodea) using new quantitative methods

open access: closedInvertebrate Reproduction & Development, 2001
Summary Previous studies on the reproductive cycle of echinoderms have used the gonadal index and descriptions of histological preparations of the gonad to determine reproductive state. The size frequency distributions of oocytes are also commonly used to delineate the various phases of the reproductive cycle.
