Thermo Fisher, AM9261, EDTA (0.5 M), pH 8.0, RNase-free, 500 mL

EDTA (0.5 M), pH 8.0, RNase-free, 500 mL is designed for preparing nuclease-controlled molecular-biology buffers and solutions that require EDTA at a defined alkaline pH. This ready-to-use Ambion solution contains 0.5 M ethylenediaminetetraacetic acid at pH 8.0 and is supplied as 500 mL of molecular-biology-grade liquid. The formulation is certified RNase-free and undergoes testing for contaminating nonspecific endonuclease, exonuclease and RNase activities. EDTA chelates divalent metal ions and is used as a component in workflows where metal-dependent nuclease activity must be controlled, including DNA and RNA sample preparation and storage buffers. The concentrated 0.5 M stock allows the required working concentration to be prepared by dilution without weighing and dissolving EDTA powder or readjusting the stock pH. The 500 mL bottle is particularly suitable for laboratories preparing multiple batches of extraction buffers or handling frequent RNA-related work. Store at room temperature; the liquid ships at ambient temperature. The exact 500 mL format must be distinguished from smaller or larger package options under the same product family.
