Descripción

General description

Ethylenediaminetetraacetic acid (EDTA) is a polyprotic acid. The four carboxylic acid and two amine groups with lone-pair electrons of EDTA can chelate calcium and several other metal ions.

Ethylenediaminetetraacetic acid disodium salt solution is a chelating agent suitable for molecular biology applications.

Application

Ethylenediaminetetraacetic acid disodium salt solution has been used:

• in Tris hydrochloric acid (HCl) for digesting proteinase-K to determine the amount of DNA in the corneal sample
• with papain to digest corneal samples for the quantification of glycosaminoglycan (GAG) content
• in pretreatment for detaching epithelial cells grown to 80% confluency
• to prepare stock solutions for lysis buffer
• in the preparation of urea lysis buffer
