In the intricate world of molecular biology and diagnostics, the ability to precisely label proteins with reporter molecules is a fundamental requirement for many research and clinical applications. N-Succinimidyl 6-(3-Maleimidopropionamido) Hexanoate (SMPH), a potent heterobifunctional crosslinker, offers unparalleled versatility in achieving these labeling goals. As a dedicated manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. is proud to supply researchers with this essential reagent, empowering advancements in protein modification techniques and diagnostic assays. SMPH's key advantage lies in its dual reactivity: a maleimide group that targets sulfhydryl (-SH) groups and an NHS ester group that targets primary amines (-NH2). This allows for the selective conjugation of molecules to specific sites on proteins, typically cysteine and lysine residues, respectively. The maleimide moiety forms a robust thioether linkage, while the NHS ester forms an amide linkage. These linkages are stable and are formed under mild conditions, preserving the integrity and function of the labeled proteins. The 14.3 Angstrom spacer arm separating the two reactive groups is crucial, providing optimal flexibility and preventing steric hindrance between the protein and the attached label. This makes SMPH an ideal choice for a wide range of protein labeling applications. Researchers can use SMPH to attach fluorescent probes, such as FITC or Cy dyes, to proteins for imaging and flow cytometry. It is also used to immobilize proteins onto surfaces for biosensors or diagnostic arrays, or to conjugate proteins to solid supports for affinity purification. In the development of diagnostic kits, SMPH is invaluable for creating labeled antibodies or antigens that are central to immunoassay technologies. The precision offered by SMPH in attaching labels ensures the sensitivity and specificity of these diagnostic tools. For scientists looking to buy SMPH crosslinker, NINGBO INNO PHARMCHEM CO.,LTD. offers a reliable source of high-purity SMPH. Our commitment as a manufacturer in China to rigorous quality control means that researchers can depend on our product for consistent and reproducible results in their protein labeling and diagnostic development projects.
