High-capacity, low-leakage Ni-NTA resin for purification of His-tagged recombinant proteins
G-Bond Ni-NTA Agarose Resin is a high-performance, crosslinked agarose matrix charged with nitrilotriacetic acid (NTA)–chelated nickel ions (Ni²⁺) for highly selective purification of 6×His-tagged recombinant proteins under both native and denaturing conditions.
Engineered to match or outperform leading MNC products (Qiagen, Thermo Fisher, Sigma, Cytiva), G-Bond Ni-NTA provides superior binding capacity, exceptional mechanical stability, minimal nickel leakage, and excellent reusability, making it ideal for research labs, production facilities, and bioprocess development workflows.
● Industry-leading binding capacity (40–60 mg His-tag protein/mL resin)
Significantly higher than many standard Ni-NTA resins (Qiagen: 20–30 mg/mL; Thermo HisPur: 30 mg/mL). Ideal for high-yield purification and scale-up.
● Very low nickel (Ni²⁺) leakage
Highly stable NTA–Ni chelation ensures minimal Ni²⁺ bleed-through, improves purity, and protects downstream enzymatic reactions.
● Highly crosslinked Superflow-grade agarose beads
Provides excellent flow uniformity, mechanical strength, and compatibility with gravity columns, batch purification, and low-pressure FPLC.
● Works under both native and denaturing conditions Compatible with: 8 M Urea
6 M Guanidine-HCl
Reducing agents
Detergents
High-salt buffers
● Reusable up to 20–25 cycles without loss of performance
Regeneration and recharging protocols allow long-term economic use.
● Superior clearance of host-cell proteins & contaminants
Highly selective Ni²⁺–His binding reduces nonspecific protein contamination, delivering highly pure elution fractions.
● Economical & high-performance alternative to MNC resins
Delivers global-standard purification at significantly reduced cost.
