Technical Data
Cullin 3 (NT) (CUL-3)
CUL-3 is a member of the family of human cullin genes (CUL-1,-2,-3,-4a,-4b, and-5), homologous to the S. cerevisiae cdc53 gene. Cullin-3 is proposed to be a part of E3 protein-ubiqutinnn ligase. It forms a tight complex with cyclin E and targets it for ubiquitination, which leads to its degradation by protesomes. Cyclin E is an activator of cdk2, which leads the cell to S phase. Cul-3-/-mice show increased accumulation of Cyclin E protein and disruption of normal cell cycle regulation in vivo. Thus Cullin-3 is important in the regulation of S phase of cell cycle.

Suitable for use in ELISA, Western Blot, Immunoprecipitation. Other applications not tested.

Recommended Dilution:
ELISA: 1:2000-1:10,000
Western blot: 1:500-1:1,000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
