Anti-ELF5 Antibody

ELF5 (E74-like factor 5) is an ETS-family transcription factor with essential roles in epithelial lineage specification, trophoblast differentiation, and mammary gland biology. It is widely studied as a lineage marker in breast cancer subtyping, particularly for claudin-low and luminal progenitor states.

This rabbit polyclonal antibody from Antibodies.com is raised against ELF5 and validated for Western blot, immunohistochemistry, and immunofluorescence workflows. It cross-reacts with human, mouse, and rat samples, supporting comparative studies in developmental biology, oncology, and reproductive research. The reagent is supplied unconjugated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, provided as a 100 µl vial that dilutes cleanly into standard blocking buffers.

Researchers commonly use this reagent to profile ELF5 expression in mammary epithelial models, placental tissue sections, and a range of carcinoma cell lines. The polyclonal format increases the likelihood of recognising multiple epitopes on the target, which is helpful when working with formalin-fixed paraffin-embedded material where epitopes may be partially masked by fixation chemistry.

For best results, store refrigerated at 4 °C for short-term use. For longer-term storage, aliquot and freeze at -20 °C, avoiding repeated freeze-thaw cycles to preserve antibody activity. This product is intended for research use only.
