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 .
