PAMAM Dendrimer G3.0 Amidoethanol (water solution)

PAMAM dendrimer G3.0 amidoethanol (PAMAM G3.0 amidoethanol) is a polyamidoamine (PAMAM) dendrimer with hydroxyl termini.1 It is approximately 30 Å in diameter in PBS and has 32 surface groups. PAMAM G3.0 amidoethanol is an antagonist for the pore-forming channels anthrax protective antigen 63 (PA63) in lipid membranes (IC50 = 44.9 nM).2 It inhibits aggregation of amylin containing a serine-to-glycine substitution at position 20 (amylinS20G) in a concentration-dependent manner and amylinS20G-induced toxicity in MIN6-K8 and NIT-1 pancreatic β-cells at 6 µM.3 Topical application of PAMAM G3.0 amidoethanol (1 mg/ml) encapsulating the synthetic glucocorticoid dexamethasone (Item No. 11015) increases the levels of dexamethasone in the sclera, conjunctiva, and cornea in isolated rabbit eyes.4 It reduces tail growth in C. riparius larvae and induces DNA damage in a comet assay using C. riparius larval homogenates when used at concentrations of 10 or 100 ppm.5WARNING This product is not for human or veterinary use.
