Phytochelatin 2 (PC2) TFA(CAT: I040418) is a tripeptide-based phytochelatin with the general structure (γ-Glu-Cys)₂-Gly, supplied as a trifluoroacetate salt. It functions as a crucial metal-chelating agent in plants and biological systems, binding heavy metals such as cadmium, lead, and mercury to prevent toxicity and maintain intracellular metal homeostasis. PC2 forms stable complexes with metal ions, facilitating their sequestration and detoxification. This compound is widely used in environmental toxicology, plant physiology, and metal homeostasis studies to investigate mechanisms of metal tolerance and stress response. PC2 TFA is also valuable in research on antioxidant defense and metal regulation in eukaryotic cells.
