Nucleus.

Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-118', rendering chromatin heritably changed in its expressibility. Needed to maintain expression patterns of the homeotic selector genes of the Antennapedia (Antp-C) and Bithorax (BX-C) complexes, and hence for the maintenance of segmental determination.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Delivery time may differ from different purchasing ways or locations, please kindly consult us for specific delivery times.

Store at -20 °C/-80 °C upon receipt, aliquoting is necessary for multiple use.

The shelf life is related to many factors, including storage state, buffer ingredients, storage temperature, and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C.

Repeated freezing and thawing are not recommended.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Store working aliquots at 4 °C for up to one week.
