Alkali Scientific Culture Tubes, 14mL, 17 x 100mm Polystyrene (PS) with Cap, 1/Sterile Peel, 500/cs
These disposable sterile tubes are made of high quality polystyrene (PS) that will withstand temperatures from -190˚ to +120˚C. They are also available in crystal clear polystyrene (PS) with a more limited range of 0˚ to 70˚C. Caps are made of polyethylene (PE) and have the popular two position design (up/loose for aerobic work and down/sealed for anaerobic cultures). Polystyrene tubes may be centrifuged at up to 2000xg. Polypropylene tubes withstand higher forces, up to 4000xg.

Enzo Life Sciences NUCLEAR-ID Green cell cycle kit (1Kit)
NUCLEAR-ID Green Cell Cycle Analysis Kit provides a convenient approach for studying the induction and inhibition of cell cycle progression by flow cytometry. The kit is suitable for (1) determining the percentage of cells in a given sample that are in G0/G1, S and G2/M phases, as well as to quantify cells in the sub-G1 phase prior to apoptosis, and (2) DNA studies in live, permeabilized and fixed cells for normal cell lines and cell lines exhibiting multiple ploidy levels. The kit contains sufficient reagents for approximately 100 flow cytometry assays. A control cell cycle perturbation agent, Nocodazole, is provided for monitoring changes in cell cycle dynamics. Potential applications for live-cell studies are in the determination of cellular DNA content and cell cycle distribution for the detection of variations in growth patterns, for monitoring apoptosis, and for evaluating tumor cell behavior and suppressor gene mechanisms. Applications: Flow Cytometry, Fluorescence microscopy .

Mount: 12.5mm Pin Stub
HELIX CHROMATOGRAPHY Amaze RP A1 4.6 x 250 mm, 5 um
Mixed-mode stationary phase combining reversed-phase, cation-exchange, and anion-exclusion mechanisms. Provides broad retention for amino acids, hydrophilic and hydrophobic compounds, inorganic cations, basic drugs, and anionic counter-ions. Offers strong retention for basic analytes under acidic conditions, making it suitable for challenging separations of protonated compounds. Functional groups are integrated on a single ligand. A strong acidic group (pKa ~1) is positioned in the inner layer of the stationary phase close to the silica surface, minimizing interaction with residual silanols and improving peak shape for basic analytes. Incorporates surface-bound ion-pairing functionality, enabling full MS compatibility without the need for mobile phase ion-pairing reagents. Provides comparable selectivity and retention to established mixed-mode stationary phases, enabling direct method transfer with minimal adjustment.
Electron Microscopy Sciences Aurion Carboxyl Functionalized Gold Nanoparticles, 6 nm 5 ML
This product has been developed to facilitate conjugating gold nanoparticles to molecules that cannot be conjugated via the classic direct adsorption method. The product is especially suited for covalent conjugation of small ligands. Aurion Gold Nanoparticles (Carboxyl Functionalized) are polyethylene glycol-carboxyl stabilized gold nanoparticle solutions based on defined particle sizes of 6, 10, 15 and 25nm.
Particle size: 6 nm
