Chlamydia trachomatis is the leading cause of sexually transmitted disease in the United States. Effective screening for this agent can facilitate prompt treatment and prevent its sequelae. The recent introduction of liquid-based cytology has made possible the simultaneous screening of cervical intraepithelial lesions and detection of C. trachomatis in a(More)
The pH optima and apparent Km and Vmax values were determined for nine glycosidases of the retinal pigment epithelium (RPE) of the calf. In terms of micromoles of substrate cleaved per milligram protein per hour, the following relative order of enzymatic activities was observed: beta-N-acetylglucosaminidase greater than alpha-glucosidase =(More)
We describe an immunoassay of digoxin that exploits the differential sedimentation rate between two types of latex particles in a microcentrifugal analyzer. Conventional polystyrene latex particles (relative density = 1.05), sensitized with antibody, are first suspended with the sample and then mixed with digoxin-sensitized latex particles (relative density(More)
Developmental aspects of the formation of rhodopsin in the chick were investigated. The content of rhodopsin was measured in the retina of the developing chick embryo, newly hatched and adult chickens by both spectral and immunological procedures. Rhodopsin was first detected spectrally at day 18 (stage 43) with the level increasing about 6 fold through(More)
