Comparison of Competing Products 1 and 2 with Hycells 3.0 High-Efficiency HiXpan Registered trademark Amplification performance of the NK serum-free culture kit on cryopreserved CBMCs:
Using the same cryopreserved CBMCs as seed cells, inoculate at an initial density of 5 × 10^7 cells, and separately employ Competitor Product 1, Competitor Product 2, and the 3.0 High-Efficiency Version of HiXpan. Registered trademark Three serum-free NK cell culture kits were used to perform continuous expansion, with the 2 L culture medium being completely consumed over a total cultivation period of 16 days.
Perform cell counts every 2–3 days and assess cell purity on days 7, 10, and 16.
On day 16, harvest the expanded cells and assess their cytotoxic activity.

HiXpan® Cell Culture Additive: Answers to Key Questions (Part 2)
Hycell’s maximum production capacity per batch is 200–400 units of the 500 mL format, ensuring stable supply and meeting customers’ ongoing production needs.
HiXpan® Cell Culture Additive: Key Questions and Answers (Part 1)
The blood‑derived raw materials used in HiXpan® cell culture additives comply with all regulatory requirements throughout collection, ethical review, informed consent, and commercial authorization, and are supported by a fully traceable supply chain.
This paper focuses on how Hycells transforms biological variability into engineering‑level determinism through a scientifically informed blending strategy and stringent control at the collection end.
(II) Security Assurance Section | Safety First, Defense Prioritized
Compliance‑driven traceability establishes a clear “identity” for the product, but the real test lies in safety. While a multi‑donor pooling strategy ensures batch‑to‑batch consistency, it also inevitably elevates the risk of pathogen introduction. In the face of these associated risks and challenges, Heyousheng has never compromised on its manufacturing standards—relying on more precise design to deliver on its promise of enhanced safety.
This article will examine how Hycells proactively integrates the quality management system into the hospital setting, translating compliance requirements into concrete, actionable practices starting at the sample collection stage, thereby establishing a trust‑based chain that can withstand audit scrutiny.
In selecting hPL raw materials, Heyousheng consistently upholds the principle that “safety is determined at the source.” The samples used in production are rigorously collected in accordance with applicable standards and undergo stringent donor screening, effectively mitigating the risk of disease transmission at the very outset. Moreover, from informed consent forms and ethical approvals to clinical‑grade collection under the GCP framework, Heyousheng has established a fully traceable documentation chain, ensuring that every sample is accounted for and verifiable. In contrast to the industry’s longstanding reliance on the conventional model of using expired blood supplies from blood banks, this approach represents a structural, generational upgrade.
