Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human KLF4, which shares 91.7% amino acid (aa) sequence identity with both mouse and rat KLF4.
- Molecular weight context: reported MW: 60 kDa; calculated MW: nan
- Reactivity: Human,Mouse,Rat
- Applications: IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Kruppel-like factor 4 (gut). Kruppel-like factor 4, also known as EZF or GKLF, is a protein that in humans is encoded by the KLF4 gene. This gene is mapped to 9q31.2. KLF4 gene encodes a member of the Kruppel family of transcription factors. This gene plays an important role in maintaining embryonic stem cells, and in preventing their differentiation. It is required for establishing the barrier function of the skin and for postnatal maturation and maintenance of the ocular surface. This gene involved in the differentiation of epithelial cells and may also function in skeletal and kidney development. Functional note: Transcription factor; can act both as activator and as repressor. Binds the 5'-CACCC-3' core sequence. Binds to the promoter region of its own gene and can activate its own transcription. Regulates the expression of key transcription factors during embryonic development. Plays an important role in maintaining embryonic stem cells, and in preventing their differentiation. Required for establishing the barrier function of the skin and for postnatal maturation and maintenance of the ocular surface. Involved in the differentiation of epithelial cells and may also function in skeletal and kidney development. Contributes to the down-regulation of p53/TP53 transcription. Reported localization: Nucleus.

Common research applications
- Western blotting: compare relative KLF4 levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of KLF4 across tissue regions and cell types using matched controls.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
