I. [Product Introduction]
SS-PEG-NTA-Ni is a multifunctional organic intermediate that integrates the dynamic response characteristics of disulfide bonds, the biocompatibility of polyethylene glycol, and the metal coordination ability of nitrilotriacetic acid-nickel. It can be used as a linker for the precise construction of bioconjugate systems. This compound exhibits excellent stability and controllable dissociation characteristics in catalytic reaction systems and is suitable for the synthesis of pharmaceutical intermediates and the surface functionalization modification of nanomaterials.

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

III. [Application Fields]
1. Directional coupling of proteins/antibodies and nanoparticles (based on the specific binding of the histidine tag of NTA-Ni²⁺).
2. Development of metal-ion-responsive drug delivery systems (reduction-sensitive cleavage of disulfide bonds).
3. Surface modification of biosensors (regulation of steric hindrance by PEG chains).
4. Construction of multi-level self-assembled materials (synergy of coordination and dynamic covalent bonds).
5. Immobilization carrier for catalysts (anchoring of active centers mediated by nickel ions).
