Starburst(R) (PAMAM) dendrimer, generation 4.5

PAMAM dendrimer G2.0 amine (PAMAM G2.0) is a polyamidoamine (PAMAM) dendrimer with amine termini.1 It is approximately 29 Å in diameter and has 16 surface groups. PAMAM G2.0 (15 mg/ml) in combination with erythromycin (Item No. 16486) enhances the solubility and antibacterial activity of erythromycin against S. aureus.2 It increases the cell growth rate of HEK293T and HeLa cells when used at concentrations ranging from 100 to 500 nM but is cytotoxic to the same cells when used at concentrations greater than or equal to 700 nM.3 In vivo, PAMAM G2.0 when administered in combination with fluorescein isothiocyanate-labeled dextran enhances its nasal absorption in rats.4WARNING This product is not for human or veterinary use.
