In the dynamic field of biotechnology and pharmaceutical research, the ability to precisely link molecules is paramount. N-Succinimidyl 6-(3-Maleimidopropionamido) Hexanoate, commonly known as SMPH crosslinker, stands out as a critical tool for achieving these precise molecular connections. As a premier manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing researchers with high-quality chemical reagents that drive innovation. SMPH is a heterobifunctional crosslinker, meaning it possesses two distinct reactive groups: a maleimide group and an N-hydroxysuccinimide (NHS) ester group. This unique structure allows it to form stable covalent bonds with different functional groups on biomolecules. The maleimide moiety readily reacts with sulfhydryl (-SH) groups, typically found in cysteine residues of proteins, forming a stable thioether bond. This reaction is highly specific and occurs efficiently at a pH range of 6.5-7.5. Simultaneously, the NHS ester group is highly reactive towards primary amines (-NH2), commonly present in lysine residues of proteins and N-termini. This amine reactivity allows for the formation of amide bonds. The combination of these two reactive ends, separated by a flexible hexanoate spacer arm of 14.3 Angstroms, makes SMPH an exceptionally versatile crosslinker. This spacer arm provides sufficient distance between the conjugated molecules, minimizing steric hindrance and preserving the biological activity of the components. The utility of SMPH crosslinker spans several key areas in modern science. In protein labeling, it is instrumental in attaching fluorescent dyes, biotin, or other reporter molecules to specific sites on proteins, enabling sensitive detection and visualization techniques. This is crucial for numerous diagnostic applications and research assays. Furthermore, SMPH plays a pivotal role in the synthesis of antibody-drug conjugates (ADCs). ADCs are a class of highly potent therapeutics that combine the targeting specificity of antibodies with the cytotoxic power of small molecule drugs. SMPH serves as a linker to covalently attach the drug payload to the antibody, ensuring targeted delivery to cancer cells. The reliability and efficiency of the SMPH crosslinker are vital for the success of these complex conjugate syntheses.
