SPECIES REACTIVITY:Human, Mouse
TESTED APPLICATIONS:ELISA, IF, IHC-P, WB
APPLICATIONS:E2F3 antibody can be used for detection of E2F3 by Western blot at 1 - 2 μg/ml. Antibody can also be used for Immunohistochemistry starting at 5 μg/mL. For immunofluorescence start at 20 μg/mL.
USER NOTE:Optimal dilutions for each application to be determined by the researcher.
POSITIVE CONTROL:1) Cat. No. 1369 - Human Lymph node Tissue Lysate
 2) Cat. No. 11-521 - Human Lymphoid Tissue Tissue Slide
PREDICTED MOLECULAR WEIGHT:Predicted: 51 kDa

Observed: 56 kDa
SPECIFICITY:E2F3 antibody is human and mouse reactive. At least three isoforms of E2F3 are known to exist; this antibody will detect only the largest isoform. This antibody is predicted to not cross-react with other members of the E2F transcription factor family.
IMMUNOGEN:E2F3 antibody was raised against a 15 amino acid peptide near the center of human E2F3.

The immunogen is located within amino acids 150 - 200 of E2F3.
HOST SPECIES:Rabbit

Background

BACKGROUND:The E2F transcription factor 3 (E2F3) is a member of a small family of transcription factors that function through binding of DP interaction partner proteins. E2F3 recognizes a specific sequence motif in DNA and interacts directly with the retinoblastoma protein (pRB) to regulate the expression of genes involved in the cell cycle (1). Like the related E2F1 and E2F2, E2F3 is essential for cellular proliferation and progression through the cell cycle (2). Altered copy number and activity of this gene have been observed in a number of human cancers (3).
