The fields of bioconjugation and protein engineering are at the forefront of developing advanced biomaterials, diagnostics, and therapeutics. At the heart of these innovations often lie specialized chemical compounds, and S-tert-Butylmercapto-L-cysteine (CAS 30044-51-0) plays a significant role. As a dedicated manufacturer and supplier, we provide high-quality S-tert-Butylmercapto-L-cysteine to researchers pushing the boundaries in these scientific disciplines.

Bioconjugation involves the covalent linking of biomolecules, such as peptides and proteins, to other molecules like polymers, surfaces, or drugs. The reactive thiol group of cysteine is frequently targeted for such modifications. S-tert-Butylmercapto-L-cysteine offers a protected form of cysteine, allowing for controlled conjugation. The tert-butyl disulfide group can be selectively reduced or cleaved, exposing the thiol for precise attachment to other moieties. This capability is crucial for developing targeted drug delivery systems, diagnostic probes, and antibody-drug conjugates (ADCs).

Similarly, in protein engineering, subtle modifications to amino acid residues can drastically alter a protein's stability, activity, or targeting capabilities. S-tert-Butylmercapto-L-cysteine can be incorporated into synthetic peptides or used to modify existing proteins, introducing a protected thiol that can later be functionalized. This allows scientists to engineer proteins with enhanced therapeutic properties or novel functions for industrial applications.

For professionals in these fields, sourcing reliable and high-purity materials is essential. Our S-tert-Butylmercapto-L-cysteine, with a guaranteed purity of ≥98.0%, ensures predictable reactivity and reliable outcomes in your bioconjugation and protein engineering projects. We understand the importance of consistent quality when working with sensitive biological systems.
