Readline Biotech (Ruidelin)
深圳瑞德林生物技术股份有限公司
Shenzhen synthetic-biology / enzyme-catalysis company with its own pilot lines in Shenzhen and ton-to-hundred-ton production lines in Zhuhai — a strong scale-up partner for peptides, sugars and specialty actives, and a credible candidate for external process development / custom manufacturing.

What they do
Founded in 2017, a national high-tech enterprise. Its core platform is enzyme catalysis / immobilised-enzyme technology combined with fermentation, applied to scaled production of peptides, oligosaccharides, nucleic-acid building blocks, non-natural amino acids and functional ingredients.
The product line spans GLP-1-class peptides, proxylane, ergothioneine, ectoine, collagen tripeptide, HMOs, ceramide, NAD+/NMN, GHK-Cu, carnosine and glutathione. Its footprint is 'one centre, two wings' — Shenzhen R&D/pilot, a Zhuhai bio base and a Gansu (Baiyin) chemical base, with hundred-ton-scale ingredient lines and a ton-scale pilot line referenced in Zhuhai.
Why it matters
High fit. They run real pilot-to-production scale-up (pilot lines in Shenzhen, ton/hundred-ton lines in Zhuhai) on an enzyme-catalysis plus fermentation platform, mapping directly onto Pure Advance's external biomanufacturing priority (roughly 5 L to 1000 L+) with process development and downstream — a candidate biomanufacturing / process-development partner for fermenting and scaling discovered strains and metabolites.
Their actives catalogue (ergothioneine, ectoine, ceramide, GHK-Cu, collagen tripeptide) also overlaps topical care for the Coolvex line. The differentiator is enzyme/biocatalysis rather than pure microbial fermentation, so the key question is whether classical microbial fermentation is in scope.
Visit objective & route
Assess Readline as an external process-development / custom-manufacturing (CDMO) partner for scaling discovered strains and metabolites — confirm classical fermentation scope (5 L→1000 L+) — and scope actives-catalogue overlap for the Coolvex topical line.
Approach route
Appointment-only; arrange a Shenzhen (Nanshan Hi-Tech Park) HQ meeting and, separately, a Zhuhai plant tour as a GBA day-trip; verify the correct BD/commercial contact (public contacts are HR/recruitment).
Talking points
- Do you accept external custom fermentation / CDMO projects (versus selling own-catalogue actives)?
- What classical fermentation volumes do you run (5 L → 1000 L+) versus enzyme-catalysis only?
- Can you provide cosmetic-grade quality/reg docs (COA, INCI/CAS, impurity, heavy metals, microbiology) for sensitive-area use, plus MOQ and export capability to KSA/GCC?
- Is a Zhuhai plant visit possible during the trip window?
Open questions
- Whether they accept external custom fermentation / CDMO projects, and classical fermentation volumes (5 L→1000 L+) versus enzyme-catalysis only.
- Exact Zhuhai base location and whether plant visits are possible during the trip window.
- The correct BD/commercial contact (public contacts are HR/recruitment).
- Cosmetic-grade quality/reg docs, MOQ, and export capability to KSA/GCC.
- Current funding/capacity figures (Chinese-press claims, not independently confirmed).
Risks & unknowns
- Differentiator is enzyme/biocatalysis, not pure microbial fermentation — classical aerobic fermentation scope for biocontrols is unconfirmed.
- Production lines are in Zhuhai (~2.5-3 h from Shenzhen) — a plant tour is a separate GBA day-trip from a Shenzhen meeting.
- Public contacts are HR/recruitment; verify the correct BD contact before travel.
- Funding/capacity figures are Chinese-press claims, not independently verified.
