Autofluorescence is the natural fluorescence of biological structures such as mitochondria and lysosomes, in contrast to fluorescence originating from artificially added fluorescent markers (fluorophores).

2023年3月30日 · Common Sources of Autofluorescence in Life Science Research. To properly accommodate for the presence of autofluorescence in research imaging experiments, consider the biological components that comprise your sample. Here are some frequently observed autofluorescence producers that researchers encounter in the lab: 1. Nicotinamide adenine ...

The best ways to address the issue of autofluorescence in order of preference: 1. Avoid it - not always possible. 2. Try to filter it out during image acquisition - difficult due to the broad emission spectrum. 3. Chemically remove it - can also reduce “real” signal.

Native fluorescence, or autofluorescence (AF), consists in the emission of light in the UV-visible, near-IR spectral range when biological substrates are excited with light at suitable wavelength. This is a well-known phenomenon, and the strict ...

2024年10月2日 · The term autofluorescence refers to any background fluorescence that occurs in cells or tissues that have not been stained with a specific fluorescent marker. It’s caused primarily by metabolites and cellular structures that serve as natural fluorophores within the cell.

Autofluorescence is the tissue-endogenous fluorescence caused by several different fluorophores. These include collagen and elastin as components of the connective tissue, tryptophan as a component of most proteins, and nicotinamide adenine dinucleotide (NAD), a …

Autofluorescence is the term given to describe the natural fluorescence that occurs in cells. The common compounds that give rise to this fluorescence signal include cyclic ring compounds like NAD(P)H, Collagen, and Riboflavin, as well as aromatic amino acids including tyrosine, tryptophan, phenylalanine.

Autofluorescence (AF) refers to the inherent fluorescence exhibited by cells due to the presence of certain cellular components and metabolites that fluoresce upon excitation by specific wavelengths of light. 1 Common endogenous fluorophores include cyclic compounds such as reduced pyridine nucleotides (NADH), oxidized flavin coenzymes (FMN and ...

Autofluorescence is the emission of fluorescent light from ocular structures in the absence of sodium fluorescein. Conditions that cause autofluorescence are optic nerve head drusen and astrocytic hamartoma ( Fig. 1.32 ).

Cells have a natural level of fluorescence, called autofluorescence, which can be a problem in flow cytometry data analysis. Cellular autofluorescence can be due to the presence of collagen and elastin, cyclic ring compounds such as NADPH and riboflavin, aromatic amino acids and cellular organelles such as mitochondria and lysosomes.
