Dilution 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 کاملAn Improved Radioisotope Dilution Assay for Serum Vitamin B
A radioisotope dilution assay for vitamin B12, using hemoglobin-coated charcoal, was modified in several respects, the most prominent of which was the use of cyanide extraction of sera. With these modifications, the B12 levels were significantly higher in sera from normal subjects and patients with folate deficiency, whereas sera from patients with pernicious anemia and other B12-deficient stat...
متن کاملApplication of an end point dilution method to bacteriophage assay.
In experiments on the accumulation and elimination of virus particles by Pacific oysters (Crassostrea gigas), an Escherichia coli C2 bacteriophage was used as a virus model. It became necessary to quantitate low concentrations of phage present in samples of seawater, oyster shell liquor, and oyster meats and feces. The agar overlay phage plaque assay is subject to the same limitations with rega...
متن کاملPlate-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...
