Ethos Biosciences Gram Stain, Decolorizer 75/25, 1gal, Ethos

75/25 Gram Decolorizer is a solvent blend designed for microbiology and general laboratory applications. Used as the decolorizing step in Gram staining procedures, it selectively removes the primary stain from gram-negative organisms while allowing gram-positive organisms to retain the crystal violet–iodine complex. The controlled 75/25 formulation provides consistent and reliable decolorization for accurate differentiation during microscopic evaluation. Ideal for routine diagnostic and research workflows, it supports dependable and reproducible Gram stain results. Supplied in chemically compatible containers, 75/25 Gram Decolorizer is suitable for clinical, research, and educational laboratory environments.

Sartorius INCUCYTE SX5 HD/3CLR SYS PKG

The Incucyte SX5 Live-Cell Analysis System is our more advanced offering for live-cell imaging and analysis. It leverages up to five total fluorescence channels up to three simultaneously - including a long wavelength low phototoxicity NIR channel - that makes it ideal for long-term time-lapse experiments. The system offers high-resolution imaging real-time kinetic monitoring and automated analysis capabilities. The system also supports up to six microplates in parallel meaning a wide range of vessels are supported depending on your live-cell imaging and analysis needs.  With a unique moving optical pathway cells remain undisturbed within the physiologically relevant environment of the incubator throughout the course of the assay. Additionally an automated turret boasting 4X/10X/20X objectives makes the Incucyte SX5 our most powerful instrument for multi-user laboratories looking to run multiple assays concurrently.

Biotium REDDOT2 FAR-RED NUCLEAR STAIN

RedDot™2 is a far-red cell membrane-impermeable nuclear dye similar to Draq7™ with excitation/emission at 665/695 nm. The dye is ideal for specifically staining the nuclei of dead cells with minimal cytoplasmic RNA staining. RedDot™2 provides excellent nuclear counterstaining in fixed and permeabilized cells and tissue sections without the need for RNase treatment to remove cytoplasmic RNA. The dye is highly thermostable and photostable, providing convenient handling and ideal for demanding applications such as confocal microscopy. RedDot™2 also has been used for cell number normalization for near-infrared In Cell Western™. The excitation maximum of RedDot™2 is 665 nm, but it can be efficiently excited by wavelengths from 488 to 647 nm, and therefore can be used with the 488 nm flow cytometry laser line. Supplied as a 200X stock solution in DMSO, 25 uL trial size. In Cell Western is a trademark of LI-COR® Biosciences.
