GlycoErase™ PPP1R9B Knockout HEK293 Cell Line (CAT#: GLJF-0825-JF467)

Description	GlycoErase™ PPP1R9B knockout HEK293 cell line is a HEK293 model lacking PPP1R9B (spinophilin), a PP1 scaffold enriched in dendritic spines and implicated in CNS signaling and tumor suppression. This knockout provides a human cell platform to investigate PP1 substrate targeting, synapse-like signaling assemblies, and loss of phosphatase scaffolding in cancer progression.
