Cell Biology Assays

Cayman's Protein Synthesis Assay Kit is a non-radioactive method for measuring protein synthesis that employs the cell-permeable, alkyne-containing, puromycin analog O-Propargyl-puromycin (OPP). Upon application to cells, the OPP probe incorporates into the C-terminus of translating polypeptide chains, thereby...

ICT's Autophagy Assay, Red enables researchers to detect and monitor the in vitro development of autophagy in living cells. The Autophagy Probe is cell-permeant and fluoresces red when inserted in the lipid membranes of autophagosomes and autolysosomes. Results can be read using a flow cytometer. Autophagy is a...

The Cell Meter(TM) Cell Adhesion Assay Kit is a fast and sensitive assay for measuring cell-cell or cell-surface adhesion for a variety of cell types. In this assay, cells are labeled with Calcein UltraGreen AM and allowed to adhere. After removal of nonadherent cells, The fluorescence of Calcein UltraGreen is used...

Gap junctions are specialized intercellular membrane channels constituted with connexin that selectively facilitate the passage of small molecules of <1.5 kD across cells. They are tightly regulated by voltage, growth factors, cAMP, and retinoids, and they are modulated by phosphorylation. Cell Meter(TM)...

Dihydroethidium (hydroethidine or DHE) is a widely used ethidium-based, redox-sensitive fluorescent probe. DHE has been shown to be oxidized by superoxide to form 2-hydroxyethidium (2-OH-E+) (ex 500-530 nm/em 590-620 nm) or by non-specific oxidation by other sources of reactive oxygen species (ROS) to form ethidium...

Ex: 639 nm. Em: 660 nm. Reactive oxygen species (ROS) are natural byproducts of the normal metabolism of oxygen and play important roles in cell signaling. The accumulation of ROS results in significant damage to cell structures. The role of oxidative stress in cardiovascular disease, diabetes, osteoporosis, stroke,...

Fatty acid uptake is an important therapeutic target for the treatment of many human diseases such as obesity, type 2 diabete and hepatic steatosis. The ScreenQuest(TM) Fluorimetric Fatty Acid Uptake Assay Kit provides a simple and sensitive method for the measurement of fatty acid uptake in cells containing fatty...

Cayman's Multidrug Resistance Assay Kit provides a convenient tool for studying the modulation of cellular multidrug resistance (MDR) machinery. The kit employs calcein AM, a cell-permeable nonfluorescent dye, which is cleaved intracellularly to yield the impermeant fluorescent molecule, calcein. This calcein is...

Ex: 640 nm. Em: 659 nm. Our Cell NavigatorT fluorescence imaging kits are a set of fluorescence imaging tools for labeling sub-cellular organelles such as membranes, lysosomes, mitochondria and nuclei etc. The selective labeling of live cell compartments provides a powerful method for studying cellular events in a...

Ex: 556 nm. Em: 566 nm. Reactive oxygen species (ROS) are natural byproducts of the normal metabolism of oxygen and play important roles in cell signaling. The accumulation of ROS results in significant damage to cell structures. The role of oxidative stress in cardiovascular disease, diabetes, osteoporosis, stroke,...

Lysosomes are intracellular organelles that contain enzymes used for the hydrolysis of waste materials and other cellular debris. The pH of the lysosome is ~4.5-4.8 and is optimal for these hydrolytic enzymes. The lysosomal pH gradient is maintained through vacuolar ATPases which pump protons into the lysosomes....

Autophagy Assay, Red enables researchers to detect and monitor the in vitro development of autophagy in living cells. The Autophagy Probe is cell-permeant and fluoresces red when inserted in the lipid membranes of autophagosomes and autolysosomes. Results can be read using a flow cytometer.
