Alkali Scientific Green Dye 20mL 10% Vial 10/Pk

Green Dye, 20mL Sterile Vial (10%), 10/Pk is a visualization solution designed for aseptic process simulations, operator training, and media fill validations in controlled cleanroom environments. The 10% dye concentration provides strong color contrast, allowing operators to clearly observe fluid flow, transfer accuracy, and procedural integrity during validation exercises. Packaged in sterile 20mL vials, the solution is suitable for pharmaceutical, biotechnology, and GMP regulated facilities where reliable process verification is essential. The dye supports realistic simulation of liquid handling workflows without introducing microbial contamination or chemical interference. This makes it a practical tool for validating aseptic technique, performing equipment qualification, and improving operator confidence in sterile fluid handling procedures.

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.

Biotium Calcein AM

Calcein AM is a widely used green fluorescent cell marker. Calcein AM is membrane-permeant and thus can be introduced into cells via incubation. Once inside the cells, calcein AM is hydrolyzed by endogenous esterase into the highly negatively charged green fluorescent calcein, which is retained in the cytoplasm. Calcein AM is an excellent tool for the studies of cell membrane integrity and for cell tracing. Supplied in lyophilized form or as a solution in anhydrous DMSO at 4 mM (80011-1) or 1 mg/mL (1 mM) (80011-2). Calcein AM is also offered in our Cell Viability and Cytotoxicity Assay Kit. Properties: Ex/Em (calcein) = 494/517 nm (pH 8); Colorless solid soluble in DMSO; Store at -20°C and protect from light; C46H46N2O23; MW: 995
