Anti-Elf-4 Antibody

The Elf-4 transcription factor (also known as MEF) is an ETS-family DNA-binding protein involved in hematopoietic lineage commitment, NK cell maturation, and T-cell receptor signaling. This unconjugated polyclonal reagent from Antibodies.com is raised in rabbit and validated for western blot detection of endogenous Elf-4 across human, mouse, and rat samples.

Supplied as 100 µl at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is provided in a cryoprotected format suitable for storage at -20°C. The polyclonal format allows recognition of multiple epitopes on the ~80 kDa Elf-4 protein, supporting robust signal in immunoblotting workflows.

The reagent's cross-reactivity with three mammalian species enables comparative studies of immune cell development, innate immunity, and oncogenesis research where Elf-4 dysregulation has been reported in lymphoid malignancies. Sodium azide in the buffer prevents microbial contamination during working-stock handling at 4°C.

For researchers studying ETS-family transcription factors, host defense mechanisms, or hematological disease models, this Antibodies.com polyclonal reagent offers a flexible tool for protein-level analysis of Elf-4 expression.
