Application: 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.
General description: Ethylenediaminetetraacetic acid (EDTA) 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.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
