Firefly Luciferase mRNA, derived from Photinus pyralis (Firefly), codes for a bioluminescent enzyme widely utilized as a reporter in gene regulation and function analyses. This enzyme facilitates assays pertaining to gene expression, cell viability, and in vivo imaging, among others.

Calcein-AM is a cell-permeable fluorescent dye used for the determination of cell viability.

Calcein Red AM is a fluorogenic dye that is used to assess cell viability. As the acetoxymethyl ester, Calcein Red AM is non-fluorescent but cell-permeant and is hydrolyzed to the fluorescent probe Calcein Red by intracellular esterases. Calcein Red is retained by living cells and displays excitation/emission maxima of 560/574 nm, respectively. Calcein Red AM is a red-emitting variant of the green fluorophore calcein AM , which has been used to evaluate cell viability and cytotoxicity.

CytoCalcein Violet 450 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 450 is retained by living cells and displays excitation/emission maxima of 405/450 nm, respectively.

eGFP circRNA-LNP, a lipid nanoparticle comprising eGFP circRNA, facilitates studies of RNA delivery, translation efficiency, and cell viability. This compound includes Enhanced Green Fluorescent Protein (eGFP) for expression within cells, detectable via fluorescence microscopy or flow cytometry [1].

EthD-1 is a cell-impermeant viability indicator. It acts as a high-affinity nucleic acid stain.

Resazurin is used as an oxidation-reduction indicator in cell viability.

eGFP mRNA-LNP is a lipid nanoparticle encapsulating eGFP mRNA, designed for assessments of RNA delivery, translation efficiency, and cell viability. The eGFP mRNA, once internalized by cells, expresses Enhanced Green Fluorescent Protein (eGFP), facilitating detection through fluorescence microscopy or flow cytometry [1].

4-Di-1-ASP, a styryl dye, selectively stains glioma cells within live brain tissue, facilitating microscopic analysis of cell structure, viability, and processes including proliferation, endocytosis, cytokinesis, and phagocytosis. It also allows for the observation of mitochondrial structures in living cells. The dye exhibits green fluorescence when visualized under a microscope (λ ex /λ em = 475/606 nm) [1] [2].

CytoCalcein Violet 500 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 500 is retained by living cells and displays excitation/emission maxima of 405/500 nm, respectively.

5(6)-CFDA (5-(6)-Carboxyfluorescein diacetate) is a cell-permeant esterase substrate that can serve as a viability probe that measures both enzymatic activities, which is required to activate its fluorescence, and cell-membrane integrity, which is required for intracellular retention of their fluorescent product.

Bromocresol Green, a triphenylmethane dye, serves primarily as a pH indicator transitioning from yellow (λmax=435 nm, protonated form) at pH 4.15 to blue (λmax=615 nm, deprotonated form) in alkaline environments. Utilized in biochemical analysis, it quantifies serum protein and albumin, assesses creatinine concentration, and evaluates cell viability [1] [2] [3] [4]. The dye exhibits a bio-based, yellow-green to blue-green hue.

Calcein Orange Diacetate is a fluorogenic dye that is used to assess cell viability. It is hydrolyzed to the fluorescent probe Calcein Orange . Calcein Orange is retained by living cells and displays excitation/emission maxima of 525/550 nm, respectively. Calcein Orange Diacetate is an orange-emitting variant of the green fluorophore Calcein AM , which has been used to evaluate cell viability and cytotoxicity.

Calcein tetraethyl ester, a fluorescent dye, is utilized in biological studies for its ability to penetrate cellular membranes into living cells. This property renders it valuable for assessing cell viability and short-term cell labeling.
