Other Notes

Same product — same quality — now Sigma-Aldrich brand


Ethylenediaminetetraacetic acid solution can be used to study cell biology, molecular biology, bioactive small molecules, biochemicals, solutions and reagents, inorganic salts, chelators and ethylenediaminetetraacetic acid (EDTA) and EDTA solutions. Ethylenediaminetetraacetic acid solution has been used in a study to help elucidate the role of antigen retrieval in immunostaining of ethanol-fixed smears. Ethylenediaminetetraacetic acid solution has also been used in a study to assess the uptake and release of biotin-labeled fluorescein (b-FITC) as well as immobilization of biotin-labeled glucose oxidase (b-GOx) to the polyelectrolyte microcapsules with an avidin-poly(styrene sulfonate) (PSS) membrane.
