Background Information

Transcription factor E2F1 (E2F1), also known as RBBP3, is a transcription activator that binds DNA cooperatively with dp proteins through the E2 recognition site, 5'-TTTC[CG]CGC-3' found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. E2F-1 binds preferentially RB1 protein, in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent apoptosis. The calculated molecular weight of E2F1 is 47 kDa, but the sumoylated E2F1 is bout 55-60 kDa.

Umut (Verified Customer) (08-30-2023)

It works very well, even though it is diluted a lot, i.e., 1:2000. The total protein concentration of my samples were around 2 ug/ml before adding 1:4 laemmli buffer and denature, and it is able to capture the target at low exposure times.
