Description

E2F4 is a member of the E2F family of transcription factors. The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. This protein binds to all three of the tumor suppressor proteins pRB, p107 and p130, but with higher affinity to the last two.

Application Notes

Differences in protocols and secondary/substrate sensitivity may require the E2F4 antibody to be titrated for optimal performance.

Immunogen

Amino acids 106-144 (ELQQREQELDQHKVWVQQSIRNVTEDVQNSCLAYVTHED) from the human protein were used as the immunogen for the E2F4 antibody.

Storage

After reconstitution, the E2F4 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
