Description

Urogastrone, Lys-β- CAS NO 121684-87-5 is a synthetic peptide analog of human epidermal growth factor (hEGF), specifically engineered with a lysine substitution at the beta position. This modification is critical for enhancing its stability and bioactivity in advanced research and therapeutic applications. It is an essential biochemical tool for researchers and developers in the pharmaceutical and biotechnology sectors, particularly those focused on cell proliferation, wound healing, and tissue regeneration studies.

Application

• Pharmaceutical Research & Development: As a key reference standard and active ingredient in the development of novel wound healing formulations and regenerative medicines.
• Cell Culture & Tissue Engineering: Used to stimulate the growth and differentiation of epithelial cells, keratinocytes, and fibroblasts in vitro.
• Biochemical Assay Development: Serves as a critical component in ELISA kits, bioassays, and other diagnostic platforms targeting EGF receptor activity.
• Academic & Preclinical Studies: Employed in laboratory investigations to study signal transduction pathways, receptor binding kinetics, and the molecular mechanisms of growth factors.
• Cosmeceutical R&D: Investigated for potential applications in advanced skincare products aimed at promoting skin repair and anti-aging effects.
