Express Service — What Sets Us Apart

Speed without compromise requires experienced scientists, validated protocols, and parallel processing — not shortcuts.

Lightning-Fast Turnaround

While conventional CROs take 8–12 weeks, we deliver in 14 days. Proven across 800+ projects with parallel workflows that eliminate idle time between stages.

Expert Scientists, Not Automated Pipelines

Every express project is managed by PhD-level scientists with deep antibody engineering expertise. Real expertise for complex targets — no black-box automation.

95%+ First-Attempt Success Rate

Our optimized protocols achieve industry-leading first-attempt success. If expression fails, we iterate once at no extra cost. Full refund if we miss the timeline.

APAC Timezone, Shenzhen-Based

Same-timezone collaboration with Shenzhen headquarters — real-time communication, no language barriers, faster project iteration than European or US CROs.

Competitive Pricing

40% more cost-effective than equivalent European and US CRO services. Express delivery, premium quality, Asia-based pricing — without compromising on science.

ISO 13485 Certified

GMP-ready manufacturing facilities certified to ISO 13485 medical device standards. All documentation supports CE-IVD and FDA regulatory submissions.

Express Service Success Stories

From failed batches to publication deadlines — real challenges solved in 14 days.

Pharma
★★★★★

We had two failed antibody batches from another vendor. Sekbio not only delivered working antibodies in 2 weeks, but optimized the yield by 3×. A genuine game-changer for our pipeline.

★★★★★

We originally planned 6 months for antibody validation. Sekbio Express cut it to 2 weeks. Our paper was submitted on schedule — that outcome would have been impossible otherwise.

★★★★★

We needed validated antibodies for a rapid diagnostic kit with a tight market entry deadline. Sekbio's express service was critical to our launch. Fast, reliable, exactly what we needed.

Express Service — Frequently Asked Questions

Honest answers to the questions every new client asks.

Is 2 weeks really possible? What's the catch?

No catch. We have delivered 800+ projects on schedule. The key is: experienced scientists with no learning curve, optimized protocols with a 95%+ success rate, parallel processing so no step waits on another, and priority resource allocation for every express project. The only trade-off: express service carries a 15% premium versus our standard timeline. You save months of development time and resources in return.

What if the antibody fails during expression?

Our 95%+ success rate is backed by a clear guarantee: if initial expression fails, we iterate once at no additional cost. If we cannot deliver within the guaranteed 14-day timeline, you receive a full refund. No hidden charges, no surprise costs.

Which expression system — CHO or HEK293 — should I choose?

CHO cells are preferred for complex antibodies requiring proper post-translational modifications and higher yields. Sekbio's CHO platform achieves up to 2.4 g/L. HEK293 offers faster initial expression, lower endotoxin levels, and is well-suited for early-stage research quantities. Our project scientists recommend the optimal system during the initial consultation based on your antibody's structure and downstream application.

Can I request specific modifications — tags, mutations, isotype changes?

Yes. Most modifications (His-tag, Fc fusions, specific point mutations) add 0–3 days to the timeline and $1,000–$2,500 to the project cost. Discuss your specific requirements at project initiation so we can confirm feasibility within the express window.

What documentation is provided with delivery?

Every express delivery includes: sequencing data, expression QC data, SDS-PAGE analysis, HPLC purity report, endotoxin test results (LAL assay, <1 EU/mL), Certificate of Analysis, stability summary, and a technical summary report. All documents are formatted to support CE-IVD and FDA regulatory submissions.

Can I scale up production after the express validation?

Yes. Sekbio provides scale-up protocols as part of the express deliverables. Clients can produce in-house using the provided methods, or continue with Sekbio for scale-up at 40 mL–20 L (HEK293) or commercial-scale CHO production. Ongoing technical support is included with every project.
