Meaning: 1. To determine the content and quality (of ore) or that of a biochemical substance. 2. To assess the nature of something, to evaluate it.Notes: This verb may be used as a noun if we only shift the accent to the first syllable: [æ-say]. Someone who plies the trade ...
Although a particular overlay medium has been selected in most laboratories on the basis of personal preference or expertise available, generally, for the flaviviruses that grow more slowly (such as some strains of DEN-3 virus) a double overlay method is superior because an overlaid monolayer can...

disease related conformation to provide a treated, denatured sample; contacting the treated, denatured sample with a binding partner which binds the denatured, second, disease related conformation of the protein; and detecting the second, disease related conformation of the protein based on binding to...
If a known amount of a known ligand and a macromolecule or biological component are brought together in solution, then the amount of ligand which is still freely present in solution will depend on the concentration and the coefficient of binding to the macromolecule or biological component. Binding...
The two systems were tested on the basis of expression levels of the genetic markers vimentin, E-cadherin, N-cadherin and GAPDH in A549 lung carcinoma cells at two known concentrations. Furthermore, the influence of a known PCR inhibitor commonly found in blood samples, heparin, was evaluated ...
Therefore, it is critical that we be able to test whether a variant affects gene regulation. Current approaches for measuring a variant’s effect on gene expression fall into two categories, each with its own limitation. Indirect methods, such as whole-genome epigenetic assays, can only identify...
