I. [Product Introduction]
Mal-PEG-NTA-Ni is a multifunctional organic intermediate that combines the click chemical reactivity of maleimide, the biocompatibility of the PEG chain, and the metal chelating properties of NTA-Ni. It can be used as an efficient catalyst or pharmaceutical intermediate for bioconjugation and metal ion directional assembly. Its modular design is suitable for site-specific modification of proteins/polypeptides and controlled synthesis of metal nanomaterials, with precise molecular weight control and excellent batch stability.

II. [Product Details]
 【Appearance】 Depending on the molecular weight, it appears as a white/off-white solid or a viscous liquid.
 【Stability】 Store under refrigeration and avoid repeated freeze-thaw cycles.
 【Solvent】 Common organic solvents such as chloroform, dichloromethane, and DMSO.
 【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
 【Storage Conditions】 Store sealed and dry at a low temperature below 4°C.
 ▪ Note: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Areas]
 1. Site-specific modification of proteins (specific binding of maleimide groups to sulfhydryl groups).
 2. Construction of metal ion affinity chromatography carriers (NTA-Ni chelates His-tagged proteins).
 3. Preparation of nano-metal catalytic materials (directional loading and size control of nickel ions).
 4. Development of in vitro diagnostic reagents (bioconjugation and signal amplification systems).
 5. Surface functionalization of polymer materials (the PEG chain enhances water solubility and anti-fouling properties).
