Measurement of Cell Viability

2012
An overview of the methods for assessing cell viability is presented. Different protocols of the most commonly used assays are described in detail so that the readers may be able to determine which assay is suitable for their own projects in plant biotechnology.

Measurements of magnesium in mononuclear cells

Science of The Total Environment, 1985
In this study analysis of magnesium in mononuclear cells was compared to that in muscle in patients and healthy controls. Mononuclear cell concentrations of magnesium expressed as nmol/mg cell protein correlated significantly with muscle biopsy concentrations of magnesium (r = 0,68; p less than 0,001).

On the measurement of cell adhesiveness

Journal of Experimental Zoology, 1970
AbstractFour parameters that might be related to either the cell surface or cell adhesiveness were examined as a function of embryonic age in chick cells, and compared to each other. The four parameters were: (1) size of aggregates formed in shaker culture; (2) rate of aggregation in shaker culture; (3) sorting‐out behavior; (4) surface charge density.

The measurement of cell adhesion

Experimental Cell Research, 1961
Abstract Some of the theoretical physical aspects of the measurement of cell adhesion by distractive techniques have been discussed. It is suggested that when adherends are separated by distraction, the tensile strengths of the adherend surfaces may be measured instead of the adhesive forces holding them together.

Measuring Degranulation of Mast Cells

Current Protocols in Immunology, 1993
AbstractThis unit describes methods for measuring exocytosis of preformed mediators from secretory granules as an indication of IgE receptor‐mediated activation of mast cells. The first basic protocol describes the measurement of biogenic amines (serotonin and histamine) secreted by activated rodent mast cells (for serotonin) or rodent and human mast ...

Measuring Ubiquitin Conjugation in Cells

2005
Protein ubiquitination is crucial to many diverse and critical functions of cells. Although it has been long known that conjugation of ubiquitin to proteins results in their destruction by the proteasome, recently it has become apparent that reversible protein ubiquitination, particularly monoubiquitination, performs regulatory functions in cells ...

Enzyme Measurements on Single Cells

Science, 1974
A simple and sensitive procedure has been developed for enzymatic assays in single cells and applied to the measurement of β-glucuronidase in single parenchymal cells of liver. Cells deposited in microdroplets under oil were ruptured by freezing and thawing and allowed to react with a fluorogenic substrate. The fluorescence is developed by diffusing an

Measurement of single-cell dynamics

Nature, 2010
Populations of cells are almost always heterogeneous in function and fate. To understand the plasticity of cells, it is vital to measure quantitatively and dynamically the molecular processes that underlie cell-fate decisions in single cells. Early events in cell signalling often occur within seconds of the stimulus, whereas intracellular signalling ...

Uncertainty in cell confluency measurements

2015 IEEE International Symposium on Medical Measurements and Applications (MeMeA) Proceedings, 2015
Pharmaceutical industries have declared their need of metrology in the cellular field, to improve new drugs developing time and costs by high-content screening technologies. Cell viability and proliferation tests largely use confluency of cells on a bi-dimensional (2D) surface as a biological measurand.
