Notes: PAMAM dendrimer G5.0 amine (PAMAM G5.0) is a polyamidoamine (PAMAM) dendrimer with amine termini.{51536} It is approximately 54 Å in diameter and has 128 surface groups. PAMAM G5.0 (10 µg/ml) reduces viability, induces cell cycle arrest at the sub-G1/M phase, and increases lactate dehydrogenase (LDH) release from RAW 264.7 macrophages.{68596} It also induces DNA fragmentation in the same cells when used at a concentration of 15 µg/ml. PAMAM G5.0 in complex with siRNA targeting Pou5f1 mRNA, the gene encoding Oct4, reduces Oct4 expression in mouse embryonic stem cells.{68597} Intravenous administration of PAMAM G5.0 in complex with reporter gene DNA increases reporter gene expression in the lung, spleen, and liver, but not the heart, in mice.{68598} Conjugates of PAMAM G5.0 with the contrast agent gadolinium increases small vessel contrast quality compared to conjugates of gadolinium with the cell-impermeable metal chelating agent diethylenetriaminepentaacetic acid (DTPA; Item No. 33307).{68599}
