Product Overview
Clone ADHF-5 is a rabbit monoclonal antibody that recognizes early growth response protein 1 (gene EGR1) in human samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 57.5 kDa, and the supplier reports an observed band at about 58 kDa.
Early growth response 1 (EGR1) is a zinc finger transcription factor encoded by an immediate early gene. It is rapidly induced by growth factors, stress and neuronal activity and regulates genes linked to growth, differentiation and synaptic plasticity, making it a common marker of cell activation.

Samples with a confirmed band (WB): human MCF-7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:1000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human tonsil tissue, human thyroid cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human egr1.
Reactivity Notes
The supplier lists reactivity with human. UniProt places early growth response protein 1 in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Detected in neutrophils (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
