Le kit d’expression génétique Imagene Green™ lacZ contient un substrat de galactosidase à base de fluorescéine qui a été modifié de façon covalente pour inclure une fraction lipophile à 12 atomes de carbone, C12FDG. Une fois à l’intérieur de la cellule, les substrats sont clivés par la β-galactosidase, produisant ainsi un produit fluorescent bien retenu par les cellules, et ce, grâce à la probable pénétration de la queue lipophile dans la membrane cellulaire. Outre le FDG C12, les kits incluent également l’inhibiteur à large spectre de la β-galactosidase, le PETG et le diphosphate de chloroquine pour inhiber l’hydrolyse acide du substrat.

Abstract
Rapid flow cytometric method for measuring senescence associated beta-galactosidase activity in human fibroblasts.
Authors:Noppe G, Dekker P, de Koning-Treurniet C, Blom J, van Heemst D, Dirks RW, Tanke HJ, Westendorp RG, Maier AB,
Journal:Cytometry A
PubMed ID:19777541
'Senescence associated-beta-galactosidase (SA-beta-gal) activity is a widely used marker for cellular senenescence. SA-beta-gal activity is routinely detected cytochemically, manually discriminating negative from positive cells. This method is time-consuming, subjective and therefore prone to operator-error. We aimed to optimize a flow cytometric method described by other workers using endothelial cells to ... More
Optical imaging fiber-based single live cell arrays: a high-density cell assay platform.
Authors:Biran I, Walt DR
Journal:Anal Chem
PubMed ID:12141663
'A high-density, ordered array containing thousands of microwells is fabricated on an optical imaging fiber. Each individually addressable microwell is used to accommodate a single living cell. A charged coupled device (CCD) detector is employed to monitor and spatially resolve the fluorescence signals obtained from each individual cell, allowing simultaneous ... More
An optimized electroporation protocol applicable to a wide range of cell lines.
Authors:Baum C, Forster P, Hegewisch-Becker S, Harbers K
Journal:Biotechniques
PubMed ID:7873174
'A number of transfection methods for mammalian cells are available; however, many cell lines may appear resistant to efficient transfection, or at best, necessitate lengthy optimization procedures in recommended protocols. We describe here an electroporation protocol that yields highly efficient gene transfer (20%-100% of surviving cells) in all 19 cell ... More
Mapping mechanisms and charting the time course of premature cell senescence and apoptosis: lysosomal dysfunction and ganglioside accumulation in endothelial cells.
Authors:Patschan S, Chen J, Gealekman O, Krupincza K, Wang M, Shu L, Shayman JA, Goligorsky MS,
Journal:Am J Physiol Renal Physiol
PubMed ID:17928415
'Endothelial cells subjected to glycated collagen I develop premature senescence within 3-5 days, as revealed by increased senescence-associated beta-galactosidase activity, decreased proliferation, and an increase in cell size. Here, we analyzed the time course and possible mechanisms of this process. Lysosomal integrity studies revealed a rapid collapse of pH gradient ... More
