In this study, a slow-responding chemo-optical sensor for dissolved oxygen (DO) integrated into a 96-well plate was developed. The slow response time ensures that the measured oxygen value does not change much during plate transport to the microplate reader. The sensor therefore permits at-line DO measurement of microbial cultures. Moreover, it eliminates the necessity of individual optical mea...
A microplate-format assay for measurement of histamine release by activated rat peritoneal mast cells, with accompanying microplate-format spectrofluorometric assay of histamine, is demonstrated. Reproducibility and linearity of the histamine assay are comparable to the historical large format assay. Transfer of samples in the 96-well format, from histamine release through spectrofluorometric a...
Open reduction and internal fixation of mandibular fracture in an 11-month-old infant: a case report
Mandibular fractures in infants are rare. This case report describes management of a mandibular fracture in an 11-month-old infant using a microplate and screws with open reduction. The surgical treatment was successful. Because the bone fragments were displaced and only the primary incisors had erupted, conservative treatment, such as an acrylic splint and circummandibular wiring, was not reco...
The design, fabrication, and operation of a radial capillary array electrophoresis microplate and scanner for high-throughput DNA analysis is presented. The microplate consists of a central common anode reservoir coupled to 96 separate microfabricated separation channels connected to sample injectors on the perimeter of the 10-cm-diameter wafer. Detection is accomplished by a laser-excited rota...
The promiscuity of a collection of enzymes consisting of 31 wild-type and synthetic variants of CYP1A enzymes was evaluated using a series of 14 steroids and 2 steroid-like chemicals, namely, nootkatone, a terpenoid, and mifepristone, a drug. For each enzyme-substrate couple, the initial steady-state velocity of metabolite formation was determined at a substrate saturating concentration. For th...
Commercially available analytical kits for the estimation of total antioxidant status are expensive and time-consuming. Most of the commercially available kits for total antioxidants estimation are based on the principle of suppression of ABTS radical cation formation by antioxidant in the serum sample. The method requires stringent assay conditions, like exact incubation time and the temperatu...
monplace of all disposable labware. Its most common format consists of 96 individual wells arranged in eight rows and 12 columns with dimensions defined by the American National Standards Institute1 through an initiative sponsored by the Society for Biomolecular Sciences in 1996. There are a myriad of microplate types, including different well densities from several wells to several thousand we...
