Cellular assays have always been a powerful tool in the research lab. They are incredibly versatile, and can be designed to measure virtually any cellular or biochemical function. Sensitive detection of fluorescent probes aid in evaluating cell signalling and death pathways, which is useful for the rapid quantification of cell viability. Cellular assays can be used to measure the effects of different treatments on cell viability and to evaluate toxic effects mediated through a variety of mechanisms.

Cell proliferation assay kit, WST-1

Supplier: Cayman Chemical

WST-1 Proliferation Assay Kit provides an easy to use tool for studying the induction and inhibition of cell proliferation in any in vitro model. The assay is based on the reduction of tetrazolium salt WST-1 to soluble formazan by electron transport across the plasma membrane of dividing cells. This kit will also allow investigators to screen drug candidates involved in regulation of cell cycle.

Cell viability assay kits

Supplier: Biotium

MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.

CFDA SE Cell proliferation assay kit

Supplier: Biotium

Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.

Ubiquitin conjugating kit (HeLa lysate-based)

Supplier: Enzo Life Sciences

1. Ubiquitinylation of specific endogenous HeLa lysate proteins, followed by their immediate detection/analysis using antibodies to the protein/s of interest, indicating a particular protein is a substrate for the ubiquitin-proteasome pathway. 2. Ubiquitinylation of proteins of interest contained in exogenously added expression culture/cell extracts or tissue lysates/extracts, followed by their immediate detection/analysis or isolation/purification for use in subsequent experiments. 3. Modification of proteins using ubiquitin derivatives or mutants for improved detection/analysis or investigation of alternative (non-proteasomal) ubiquitin related pathways in subsequent experiments. For example, biotinylated-ubiquitin (Prod. No. BML-UW8705), for sensitive detection

Lyso-ID® red detection kit (GFP-CERTIFIED®)

Supplier: Enzo Life Sciences

For use with GFP-expressing cell lines, as well as cells expressing blue, cyan or yellow fluorescent proteins.

Supplier: Enzo Life Sciences

The FLUOR DE LYS® HDAC fluorometric activity assay kit is a sensitive and convenient alternative to protocols utilizing radiolabeled, acetylated histones or peptide/HPLC methods for the assay of histone deacetylases. It is based on the unique FLUOR DE LYS® (Fluorimetric Histone deAcetylaseLysyl) substrate and developer combination and provides an assay that can be carried out in two simple mixing steps, all on the same 96-well plate. Histone deacetylase inhibitors have shown promise as anti-tumor agents and naturally this has stimulated interest in the screening of compounds for HDAC inhibition.

Live bacterial gram stain kit

Supplier: Biotium

Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF™594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacterial will be stained with blue fluorescence only.

FLUOR DE LYS® HDAC8 fluorometric drug discovery kit

Supplier: Enzo Life Sciences

A Fluor-de-Lys® fluorescent assay system. The HDAC8 Fluorescent Activity Assay/Drug Discovery Kit is a complete assay system designed to measure the lysyl deacetylase activity of the recombinant human HDAC8 included in the kit. The kit is ideal for chemical library screening for candidate inhibitors or activators or kinetic assay of the enzyme under varying conditions. The Fluor de Lys® HDAC8 assay is based on the Fluor de Lys® Substrate and Fluor de Lys® Developer combination. The assay procedure has two steps. First, the Fluor de Lys® Substrate, which comprises an acetylated lysine side chain, is incubated with HDAC6. Deacetylation of the substrate sensitizes the substrate so that, in the second step, treatment with the Fluor de Lys®Developer produces a fluorophore.
