Technical Data
Cullin 1 (CT) (CUL-1)
Cullin proteins assemble a large number of RING E3 ubiquitin ligases and regulate various physiological processes. It has been shown that the SKP1, CUL1, F-box (SCF) containing pathway, although similarly used by the mammalian CUL1, is not shared by other cullin members. This implies that most cullins may use a SKP1/F-box-independent pathway to facilitate protein degradation. The majority of CUL1 has been found in a complex with CAND1 and ROC1, independent of SKP1 and F-box protein SKP2. Data suggests that CAND1 regulates the formation of the SCF complex, and its dissociation from CUL1 is coupled with the incorporation of F-box proteins into the SCF complex, causing their destabilization.

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

Recommended Dilution:
ELISA: 1:2,000-1:10,000
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.
