Type II topoisomerase family

Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes. During meiosis, it disrupts heterochromatic connections between achiasmate and chiasmate homologs after spindle assembly so that chromosomes can separate at prometaphase I. During mitosis, it functions in the separation of sister chromatids by establishing amphitelic kinetochore attachments in mitotic spindles. May have a role in chromatin condensation and chromosome structure. May be involved in X-chromosome dosage compensation, perhaps by modifying the topological state of compensated genes. Regulates activity of the gypsy chromatin insulator complex by binding to mod(mdg4) and preventing its degradation.

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.
