In a broad sense, any chromophoric system that absorbs light at a shorter wavelength and re-emits it at a longer wavelength is referred to as a fluorophore. A major subgroup consists of small-molecule fluorescent dyes, but fluorophores also include fluorescent proteins and various ...
Use Hoechst nuclear staining to observe chromatin morphology and qualitatively/semi-quantitatively assess apoptosis ratios. Applicable to both adherent and suspension cell apoptosis models.
Aggregation-Induced Emission (AIE) refers to the phenomenon where certain organic luminescent molecules (fluorescent dyes) exhibit enhanced light emission in the aggregated or solid-state compared to their solution state.
The cytoskeleton is an essential scaffold within cells, composed of actin, tubulin, and intermediate filaments. It plays a crucial role in maintaining cell shape, cell movement, cell division, and signal transduction. Cytoskeletal staining reagents not only help researchers visualize the ...
In cell biology research, staining techniques are essential tools for observing the internal structures and functions of cells. The endoplasmic reticulum (ER) and other organelles such as mitochondria, Golgi apparatus, and lysosomes play specific biological roles.
Amine-reactive probe labeling techniques are widely used for the labeling and tracking of biomolecules, especially in the modification of proteins and nucleic acids.
Ethidium bromide (EtBr) is a classical fluorescent dye widely used in molecular biology research. Its chemical structure consists of a tri-benzimidazole, which can intercalate between the base pairs of DNA or RNA, significantly enhancing its fluorescence signal. Initially discovered as a ...
Besides the optical phenomena of refraction, scattering, interference, and diffraction in partially or totally transparent objects, which can result in colour impressions such as rainbows, sky blue, sparkling soap bubbles, gorgeous peacock feathers, or thin oil films and layers, the colours of ...
