Aurintricarboxylic Acid a cell-permeable polyanionic, polyaromatic compound employed as a powerful inhibitor of cellular processes, including apoptosis, that are dependent on the formation of protein-nucleic acid complexes. It binds to a FGF and reduces its angiogenic activity. Aurintricarboxylic Acid may act to inhibit apoptotic cell death in various cell types induced by a variety of factors. It has also been demonstrated to be a potent inhibitor of DNA topoisomerase II (IC50= 75 nM for the yeast enzyme as measured by relaxation assays) that inhibits angiogenesis. Aurintricarboxylic Acid inhibits von Willebrand factor binding to platelets and reduces glutamate-induced neuronal injury. Aurintricarboxylic Acid also stimulates the tyrosine phosphorylation of MAP kinases, Shc proteins, phosphatidylinositol 3-kinase, and phospholipase Cgamma and inhibits both major calpain isoforms (IC50 = 22 muM and IC50 = 10 muM for mu-calpain and m-calpain, respectively).

Is this chemical available as an Immobilized product. Has it bee3n attached to a bead [ agarose, sepharose,glass,alginate etc.]. I need this chemical attached to a physical support so that i can use it in the lab.

Asked by: Kennethite
Thank you for your question. No this is not attached to a bead, after looking into it we would not be able to offer an immobilized form.
