PI(4)P PIP BeadsTM are composed of agarose with 10 nanomoles of bound PI(4)P per mL of beads, enough for several protein binding experiments. Each 1 mL order of PIP Beads includes a small amount of control beads. Larger quantities of Control Beads are also available for purchase.
Storage
4 °C – do not freeze
Applications
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.
