General description

Lipid-soluble heavy metal chelator that crosses artificial and natural membranes. Auxiliary reagent in certain techniques used for measuring free Ca2+ in cells. Has an extremely high affinity for heavy metals but a low affinity for Ca2+ and Mg2+. Induces DNA fragmentation when chelated with Zn2+ and causes apoptosis in thymocytes. Strips heavy metals from liposome-trapped QUIN 2. Shown to be useful in extracting Aβ depostis from Alzheimer′s disease brain tissue.
Lipid-soluble heavy metal chelator that crosses artificial and natural membranes. Auxiliary reagent in certain techniques used for measuring free Ca2+ levels in cells. Also useful in extracting Aβ amyloid deposits from Alzheimer’s disease brain tissue. Has extremely high affinity for heavy metals but low affinity for Ca2+ and Mg2+. Induces DNA fragmentation when chelated with Zn2+ and induces apoptosis in thymocytes. Strips heavy metals from liposome-trapped QUIN 2 (Cat. No. 551826).

Warning

Toxicity: Standard Handling (A)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C) under an inert gas. Alternately, acidify (pH ≤3) with HCl for long term storage. Stock solutions are stable for up to 3 months at -20°C.
