Thermo Fisher, AM9260G, EDTA (0.5 M), pH 8.0, RNase-free, 100 mL

This 0.5 M EDTA solution is a molecular-biology-grade, RNase-free reagent adjusted to pH 8.0 and supplied ready to use in a 100 mL bottle. EDTA chelates divalent metal ions such as magnesium and calcium, allowing it to inhibit metal-dependent nuclease activity and support preparation of nucleic-acid buffers. The solution is manufactured for RNA-sensitive workflows and is tested for contaminating RNase, nonspecific endonuclease, and exonuclease activity. It can be used when preparing storage, extraction, or reaction buffers that require a defined EDTA concentration without the need to dissolve and pH-adjust solid EDTA. The liquid format improves consistency when small volumes of concentrated chelator are needed repeatedly. Store the bottle at room temperature and use clean nuclease-controlled technique to preserve reagent quality after opening.
