Alpha-Defensin vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Alpha-Defensin
Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.
Full details →Epigen
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.

| Aspect | Alpha-Defensin | Epigen |
|---|---|---|
| Mechanism | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Various routes studied including topical, local injection, and systemic administration depending on application. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Limited human use data. May cause local inflammation. Potential for immune activation effects. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
