Plate-dilution frequency technique for assay of microbial ecology.
The plate-dilution frequency technique described facilitates simultaneous enumeration of a wide range of physiologically different microorganisms in complex systems with a precision comparable to dilution tube (most probable number) methods. Replicate microsamples are inoculated from each member of a dilution series onto areas delineated on plates of prepoured solid media; the plates are incuba...
متن کاملDilution assay statistics.
A parametric method of statistical analysis for dilution assays is developed in detail from first principles of probability and statistics. The method is based on a simple product binomial model for the experiment and produces an estimate for the concentration of target entities, a confidence interval for this concentration, and an indicator of the quality of the assay called the p value for go...
متن کاملImproved IL-2 detection for determination of helper T lymphocyte precursor frequency in limiting dilution assay.
In the context of allogeneic bone marrow transplantation, an accurate estimate of the risk of developing graft-versus-host disease (GVHD) is of major interest. The pre-transplant frequency of donor's helper T-lymphocyte precursors (HTLp) directed against host's antigens may be helpful in predicting this risk. This technique relies on an indirect measurement of interleukin-2 (IL-2) secreted by t...
متن کاملFluorescence dilution technique for measurement of albumin
45 46 This study describes a high-throughput fluorescence dilution technique to measure the 47 albumin reflection coefficient (σAlb) of isolated glomeruli. Rats were injected with fluorescein 48 isothiocyanate–dextran 250 (75 mg/kg) and the glomeruli were isolated in a 6% bovine serum 49 albumin solution. Changes in the fluorescence of the glomerulus due to water influx in response 50 to an imp...
متن کاملcomparison of microbial quality assessment of water sources using multiple tube fermentation technique and enzymatic assay
background : microbial monitoring of aquatic sources is essential in the correct management of these vital sources. multiple tube fermentation (mtf) technique is currently used for assessment of the microbial quality of water sources. however, today enzymatic assay has been presented as an alternative approach for detecting indicator bacteria. the purpose of this study was to compare enzymatic ...
