Other notes

Occasionally, small volumes of PLK4 blocking peptide vial (s) may become trapped in the product vial seal during shipping and storage. If necessary, briefly centrifuge the vial in a benchtop centrifuge to dislodge any liquid on the lid of the container. Some products may need to be shipped with dry ice and an additional fee may apply for dry ice.

NCBI overview for PLK4

This gene encodes a member of the polo family of serine/threonine protein kinases. The protein is localized in centrioles, complex microtubule-based structures found in centrosomes, and regulates the duplication of centrioles during the cell cycle. Three alternately spliced ​​transcript variants have been found that encode different protein isoforms for this gene.
