Spin Traps, Spin Probes and Spin Labels

Santa Cruz Biotechnology now offers a broad range of Spin Traps, Spin Probes, and Spin Labels for use in various applications. Spin traps, spin probes, and spin labels are specialized chemicals used extensively in electron paramagnetic resonance (EPR) spectroscopy to detect, identify, and quantify free radicals and other paramagnetic species in various research contexts. Spin traps are compounds that react with transient free radicals to form more stable radical adducts, which can then be studied via EPR to provide insights into the dynamics and mechanisms of radical formation and decay. Spin probes are stable radicals that interact with their environment, allowing researchers to study the microenvironmental conditions, such as polarity and viscosity, within biological membranes or synthetic materials. Spin labels are specific molecules covalently attached to proteins, nucleic acids, or other macromolecules, facilitating the study of molecular structure, dynamics, and interactions through EPR. These tools are invaluable in fields such as biochemistry, molecular biology, and materials science, where understanding the behavior of free radicals and the structural properties of macromolecules is crucial. They enable the detailed study of oxidative stress, enzymatic activity, and the physical properties of polymers and other complex systems. By offering a diverse selection of high-quality spin traps, spin probes, and spin labels, Santa Cruz Biotechnology supports the scientific community in performing accurate and reproducible experiments, leading to new discoveries and advancements in various research areas.
