Unstable cell conditions, fluctuating experimental data... In countless late nights, have you ever blamed experimental failures on cell condition, serum batches, or even your own techniques? Yet you may have overlooked the most fundamental and critical variable: the quality of cytokines.

A reliable cytokine should not be an experimental variable but a constant. This is precisely why Yeasen Biotech created the HiActi™ High-Activity Cytokine Series: to minimize uncertainty and allow research to focus on exploration itself.

As a high-tech enterprise deeply rooted in life sciences, Yeasen Biotechnology leverages its professional R&D team, advanced production platforms, and stringent quality control systems. The company has built substantial technical expertise and market reputation in core product areas including cytokines, enzymes, and antibodies. The launch of the HiActi™ cytokine series embodies Yeasen Biotech's precise insight into research needs and concentrated technological strength. From R&D to production, quality inspection to delivery, every step demonstrates the brand's relentless pursuit of excellence.

“Three Highs” Core Strengths, Solve Key Research Pain Points

1. High Activity: Accelerate Experiments, Double Efficiency

• Technical Assurance: Innovative preparation processes precisely preserve natural protein conformation. Rigorous bioactivity validation ensures industry-leading potency in every batch.
• Your Benefits: Achieve optimal results with lower dosages, significantly reducing experimental costs; Rapid activation of cellular signaling pathways shortens reaction times; Exceptional batch-to-batch consistency ensures reliable long-term experimental projects.

2. High Purity: Precise Empowerment, Reliable Outcomes

• Technical Assurance: Employing multi-step chromatographic purification, final product purity is validated via SDS-PAGE and HPLC at > 95%, even > 98%; endotoxin levels are strictly controlled at an extremely low level of < 0.01 EU/μg, far below industry standards.
• Your Benefits: Eliminates interference from contaminating proteins, ensuring experimental specificity; ultra-low endotoxin levels are particularly suitable for sensitive cell cultures.

3. High Stability: Proven Durability with Sustained Activity

• Technical Assurance: Utilizing specialized lyophilization techniques and stable formulations, HiActi™ cytokines maintain stability during extended storage and transportation. Accelerated degradation studies confirm activity stability for over 18 months at -20°C, with minimal loss after repeated freeze-thaw cycles.
• Your Benefits: Eliminate complex storage management and concerns about experiment interruptions due to reagent expiration. High stability streamlines research workflows, providing continuous, reliable support for long-term research projects.
