Enzo Life Sciences MITO-ID Green detection kit (500 tests)

Photostable, non-toxic and selective mitochondrial dye that stains regardless of membrane potential. MITO-ID Green Detection Kit contains a proprietary membrane-permeable mitochondria-selective dye suitable for use with live-, detergent-permeabilized- and aldehyde-fixed-cells. Unlike conventional dyes (such as DiOC6(3), JC-1, rhodamine 123 and tetramethylrhodamine ethyl ester) MITO-ID Green dye highlights mitochondria regardless of their energetic state. The dye is compatible with most fluorescence detection systems, including conventional and confocal fluorescence microscopes as well as High Content Screening (HCS) platforms. The kit is useful for assessing mitochondrial morphology changes, estimating mitochondrial mass and co-localizing RFP-tagged proteins to the mitochondrial compartment. Applications: Fluorescence microscopy, Fluorescent detection.

Alkali Scientific Malachite Green, Oxalate Salt, 25 G

Malachite Green Oxalate Salt is a dye compound used primarily for laboratory staining purposes. The 25g format is suitable for small-scale laboratory experiments, particularly for visualizing biological samples under a microscope. Malachite green is commonly used to stain fungi, algae, and certain bacterial species in microbiology and histology. Its use is prevalent in studies of cell morphology, metabolic activity, and pathogen detection. The dye interacts with cellular components to produce a vibrant color, enhancing the contrast of specimens during microscopic examination. Malachite Green is often used in academic and clinical laboratories for routine staining procedures.

AdipoGen Green CMFDA, 136832-63-8, MFCD00467170, 1 mg

MF: C25H17ClO7, MW: 464.85, ≥95%, Appearance: Off-white to yellow powder. Thiol-reactive, cell permeant green fluorescent probe with high selectivity (Ex/Em: 492/517nm). This fluorescent dye is well suited for monitoring cell movement or location. Freely passes through cell membranes, where it is transformed into cell membrane-impermeant reaction products and is converted to the highly fluorescent probe (fluorescein) once the acetate groups are cleaved by intracellular esterases. The dye exhibits ideal tracking properties: it is stable, nontoxic at working concentrations, well retained in cells and brightly fluorescent at physiological pH.

AdipoGen New Indocyanine Green

Chemical. CAS 172616-80-7. Formula C46H50ClN2NaO6S2. MW 849.47. IR-820 is a near infrared dye NIR, which has a broad absorption band at 690nm in aqueous solution, with high resistance to photodegradation and photocleavage. IR-820 is an excellent probe for imaging tumors, as it can be detected in skin cells, chitosan quaternary ammonium, and subcutaneous tumors using fluorescence imaging. IR-820 is an infrared blood pool contrast agent to detect and quantify diseased tissue in live animals. IR-820 has maximal excitation and emission wavelengths of 710 and 820nm, respectively. IR-820 emission is significantly improved in vivo on serum binding to albumin, and elimination occurs predominantly via the gastrointestinal tract. IR820 has optical and thermal generation properties similar to those of indocyanine green ICG but with improved in vitro and in vivo stability.
