KH20_PURE_E2F1_Antibody_1_080222
Whole cell extracts (15 µg total protein) from Daudi, HeLa, BeWo, NTERA-2, and NIH/3T3 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 μg/mL of purified anti-E2F1 (clone KH20) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:25000 dilution (lower). Lane M: Molecular weight marker

    HeLa cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with MEOH for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with 5.0 µg/mL (1:100 dilution) of either purified mouse IgG2a, κ isotype control (Cat. No. 401501) (panel A) or purified anti-E2F1 (clone KH20) (panel B) overnight at 4°C, followed by incubation with Alexa Fluor® 594 goat anti-mouse IgG (Cat. No. 405326) at 2.0 µg/mL. Nuclei were counterstained with DAPI and the image was captured with a 60X objective. Scale: 50 µm

    IHC staining of purified anti-E2F1 (clone KH20) on formalin-fixed paraffin-embedded human colon tissue. Following antigen retrieval using Sodium Citrate H.I.E.R. (Cat. No. 928502), the tissue was incubated with 10.0 µg/mL of the primary antibody overnight at 4°C. BioLegend’s Ultra Streptavidin HRP Kit (Multi-Species, DAB) (Cat. No. 929501) was used for detection followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 μm

Description

E2F1 is a member of the E2F family of transcription factors, which is comprised of 6 members that display both activator and repressor functions. The primary functions of E2F1 are transcription activation and cell cycle regulation, namely in replication, DNA-damage response and repair, and apoptosis. E2F1 activation during G1 phase of cell cycle is vital for the transition into S phase and the subsequent replication and synthesis of DNA. Beyond its role in cell cycle control, E2F1 is a regulator of metabolism, primarily through β cell proliferation, insulin secretion, endocrine function, and adipogenesis. E2F1 activity is regulated through its binding to phosphorylated retinoblastoma protein (pRB) and through acetylation when in its pRB-free form.  

E2F1 represents a critical target in cancer therapy. Through its stimulation of mTORC1 activity and tumor malignancy and growth, as well as its contribution to the Warburg effect by inducing glycolytic genes, E2F1 often behaves as an oncogene. Additionally, E2F1 can function as a tumor suppressor. Tumor-suppressive properties stem from its role in apoptosis through association with p53 and p73, as well as through inhibition of the NF-κB signaling pathway.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.5 - 1.0 µg/mL. For immunocytochemistry, a concentration range of 2.5 - 5.0 μg/mL is recommended. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 10.0 - 20.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This product does not cross-react with mouse by WB. 

This antibody works by ICC using a variety of fixation permeabilization methods such as: fixation with either methanol or 4% PFA followed by permeabilization with either 0.5% Triton-X or 100% ice-cold methanol.
