Heterogeneous Eight Arm Polyethylene Glycol (Biotin) 7-8ARM-PEG-NHS

(Biotin) 7-8 ARM PEG NHS is composed of an eight armed PEG backbone, with seven arms carrying delivery biotin at the end and the other arm carrying NHS activated ester for specific coupling.

The comprehensive characteristics of Biotin ₇ -8ARM PEG NHS

Multi valent targeting ability

Seven biotins are distributed in an eight armed spatial pattern, enabling multi site, high affinity binding of avidin/streptavidin, significantly enhancing binding stability and targeting efficiency.

Directional single point coupling structure

Only one NHS active site is retained to enable further covalent coupling with molecules containing primary aminesThe characteristics of controllable and directional connections avoid random multi-point modifications.

Highly symmetrical and controllable 3D scaffold

Eight armed PEG forms a regular radial structure, which provides good spatial separation between biotin and a single active end, reduces steric hindrance interference, and provides predictable conformational stability.

Excellent water solubility and biocompatibility

The PEG host brings high hydrophilicity and low immunity, allowing for stable dispersion in biochemical systems and supporting mild binding of proteins, cells, or nanosystems.

Multi functional platformization features

The design of "seven targets+one activity" provides two functions: multivalent recognition and single point covalent binding, which can serve as an efficient platform for constructing complexes, probes, nanocarriers, or surface modification materials.

Space layout improves integration efficiency

Biotin is distributed on flexible PEG chains at the end of multiple arms, providing good accessibility and high binding kinetics and thermodynamic advantages when binding to affinity proteins.

Strong reaction selectivity and subsequent scalability

NHS esters have clear localization and mild reaction conditions, and can selectively form amide bonds with target primary amines, providing high scalability for the subsequent construction of composite structures (protein labeling, nanoprobes functionalization, etc.).
