Answer:EDTA disodium salt dihydrate in molecular-biology-grade powder form, supplied as 500 g.
Answer:It chelates divalent metal ions and can reduce activity of metal-dependent nucleases under appropriate buffer conditions.
Answer:No. The product is a dry powder that must be dissolved and pH-adjusted as required by the application.
Invitrogen UltraPure ethylenediaminetetraacetic acid disodium salt dihydrate is a molecular-biology-grade chelating reagent supplied as 500 g of powder. EDTA binds divalent metal ions such as magnesium and calcium, enabling control of metal-dependent enzyme reactions and helping inhibit metal-dependent nucleases in appropriate biochemical procedures. The disodium dihydrate form is commonly used to prepare EDTA stock solutions, nucleic-acid handling buffers and laboratory formulations where ionic strength and pH must be controlled. EDTA solubility and chelation depend on the prepared solution pH, so concentrate preparation should use an established protocol rather than treating the powder as a ready-to-use buffer. The material is intended for biochemical and molecular biology research, not diagnostic procedures. Store the powdered reagent at room temperature under suitable dry conditions and calculate stock concentration using the correct hydrated salt form.
Unless otherwise stated, the minimum order amount is USD 1,000.
For orders below USD 1,000, an additional handling fee may apply, or we may arrange local delivery / local handover where available.
