What does assay mean in biology?Assay: An assay is an analysis done to determine: The presence of a substance and the amount of that substance. Thus, an assay may be done for example to determine the level of thyroid hormones in the blood of a person suspected of being hypothyroid (or ...
The cells are allowed to grow to near confluency, meaning that they have grown to completely cover the bottom of the cell culture vessel. At this point, the medium is removed from the wells. Tenfold serial dilutions of the initial sample are made, in case the initial sample has too much...
Documentation of bioassay validation results is also discussed, with reference to pre-validation experiments performed to optimize bioassay performance. In the remainder of general chapter 1033 the term bioassay should be interpreted as meaning relative potency bioassay ....
the improvement wherein the reaction is carried out in the presence of an aromatic amine of the general formula ##STR20## wherein the R symbols, namely R, R1, R2, R3, R4, R5 and R6, have any of the meanings (a) to (j) given below, all other R symbols in each meaning are hyd...
Now only 5ul of cell supernatant was sufficient for the cAMP RIA, meaning that no more than IuI of serum was added to each RIA tube. These parameters were used in the patient studies described below. Patient Samples Analyzed for hFSH Content [0045] Fifteen (15) patient samples were ...
When functionalized magnetic beads immobilized with tartaric acid interacted with heme, that would be adsorbed on the magnetic beads, meaning only one tartaric acid coordinated with heme along an axis perpendicular to the porphyrin ring. Subsequently, the immobilized heme reacted with tartaric acid and...
Meaning These findings suggest that the smartphone-based LAMP assay offers an additional tool to detect COVID-19 that can be readily modified in response to novel SARS-CoV-2 variants and other pathogens with pandemic potential including influenza. Abstract Importance A critical need exists in low-...
Although widely used for ETFA analysis (more than 150 citations), the “Angiogenesis Analyzer” has never been described in details. Here, we report the algorithm and describe the meaning of the detected and modelled structures. This may facilitate the analysis of ETFA when following published ...
The polypeptides may be homologous to the host cell or may be exogenous, meaning that they are heterologous, i.e., foreign, to the host cell being utilized, such as a human protein produced by a Chinese hamster ovary cell, or a yeast polypeptide produced by a mammalian cell. In certain ...
It is not clear whether the fluorescence was then increased at constant rate; (ii) meaning of zero rate at zero oxygen concentration is not explained, whereas esterase activity of liver mitochondria producing Res independently of hydrogen peroxide have been demonstrated [46]. Half-maximal inhibition...
