Used primarily in research settings to study the complement system, particularly as a control in experiments involving Compstatin. It helps in validating the specificity and efficacy of Compstatin by serving as a non-active counterpart. This peptide is crucial in experiments aimed at understanding the inhibition of the C3 protein in the complement pathway, providing a baseline for comparative analysis. Additionally, it aids in the development of therapeutic strategies targeting complement-mediated diseases by ensuring accurate experimental results.
