Main Benefits
Why Choose Gibco™ PeproTech™ Recombinant Growth Factors and Cytokines?
Purity
Minimize confounding experimental factors with our low endotoxin levels, ensuring reliable and reproducible data. High purity is essential for sensitive applications such as cell culture and in vivo studies.
Activity
Achieve excellent value with our high bioactivity proteins, requiring smaller quantities to achieve desired effects. This efficiency reduces overall costs, particularly in large-scale or long-term experiments.
Identity
Our proteins are carrier-free and tag-free, closely mimicking native proteins for physiologically relevant outcomes. This reduces the risk of immunogenic responses in clinical applications.
