PI(3,4,5)P3 PIP Beads

Product Number: P-B345A



PI(3,4,5)P3 PIP BeadsTM are composed of agarose with 10 nanomoles of bound PI(3,4,5)P3 per mL of beads, enough for several protein binding experiment. Each 1 mL order of PIP Beads includes a small amount of control beads. Larger quantities of Control Beads are also available for purchase.


4 °C – do not freeze


PI(3,4,5)P3 PIP BeadsTM are designed for use in protein pull-down experiments to identify and characterize phosphoinositide binding proteins. Possible applications include the isolation of PIP-binding proteins present in a cell lysate or in a mixture of in vitro translated peptides, for separation by SDS-PAGE and further analysis.
