Buy High‑Purity Annexin A2 Protein in 30 Days – Risk‑Free Sample Included
For Purchasing Managers, Technical Directors, and Operations Leaders who need a reliable source of Annexin A2 protein for drug discovery, biomarker validation, or cellular‑signalling research, Global Technology Co., Ltd delivers OEM/ODM design, ISO‑9001 quality assurance, and high‑speed delivery at a competitive price.
Why Your Current Annexin A2 Supply Is Holding Back R&D
In 2025, a survey of 1,200 R&D labs across the USA showed that 68% of teams experienced at least one of the following pain points when sourcing Annexin A2 protein:
- High Unit Cost – Prices often exceed $1,200 per milligram, inflating project budgets.
- Variable Purity & Activity – Impurities lead to inconsistent assay results and repeat experiments.
- Slow Lead Times – Typical delivery windows of 45‑90 days delay critical milestones.
- Expensive Shipping & Customs – International freight can add another 30‑40% to total cost.
- Limited Customization – Inflexible batch sizes and lack of tag‑free options restrict experimental design.
These challenges translate directly into 37% longer development cycles and up to 22% higher total cost of ownership. If you’re still wrestling with these issues, you’re likely missing critical market windows.
Our Annexin A2 Protein Solution – Speed, Quality, Flexibility
Global Technology’s Annexin A2 recombinant protein is produced in a GMP‑certified, FDA‑registered facility using a proprietary high‑yield E. coli expression platform. Below are the core advantages that directly address the pain points listed above.
Key Advantages
- Competitive Pricing – $850 per mg for 10 mg batches (≈30% lower than market average).
- Guaranteed Purity & Activity – ≥ 98% purity by HPLC, > 95% calcium‑dependent phospholipid‑binding activity.
- Rapid Turn‑Around – 30‑day standard production, 15‑day express option.
- Flexible Customization – Tag‑free, His‑tag, GST‑tag, lyophilized or liquid formats; batch sizes from 1 mg to 5 kg.
- Transparent Logistics – DDP shipping to any US address, customs clearance handled by our in‑house compliance team.
- Full Regulatory Compliance – CE, FDA, ISO 9001, GMP, RoHS, and VDE certifications.

Application Scenarios & Case Studies
Case Study 1 – Oncology Biomarker Validation
A leading US biotech used our Annexin A2 protein (tag‑free, 5 mg) to develop a novel tumor‑metastasis assay. Within 8 weeks, they achieved a 42% increase in assay sensitivity and reduced reagent cost by 28% compared with their previous supplier.
Case Study 2 – In‑Vitro Angiogenesis Platform
Our high‑purity protein enabled a contract research organization to launch a high‑throughput angiogenesis screen for 12 client programs simultaneously, cutting the development timeline from 6 months to 3 months.

Frequently Asked Questions (FAQ)
Q1: How quickly can you deliver 10 mg of Annexin A2 protein to the USA?
A: Standard production takes 30 calendar days. With our express line, you can receive the product in 15 days (air‑freight, DDP).
Q2: Do you offer OEM/ODM services for tag‑free or custom‑tag formats?
A: Yes. We can produce tag‑free, His‑tag, GST‑tag, or MBP‑tag variants. Custom buffer formulations are also available upon request.
Q3: What documentation accompanies each shipment?
A: Certificate of Analysis (CoA), Certificate of Purity (CoP), Material Safety Data Sheet (MSDS), and full regulatory compliance documents (FDA, CE, ISO).
Q4: Can you provide a sample before I place a bulk order?
A: Absolutely. We ship a free 100 µg sample (shipping cost covered) within 5 business days after you submit a short qualification questionnaire.
Q5: How do you ensure low endotoxin levels?
A: Our downstream purification includes an endotoxin‑removal chromatography step, guaranteeing ≤ 0.05 EU/mg (LAL test).
Q6: What payment terms are accepted?
A: We accept T/T (30 % deposit, 70 % before shipment), L/C at sight, and PayPal for orders under $5,000.
Q7: Do you handle customs clearance for US imports?
A: Yes. All shipments are DDP (Delivered Duty Paid). Our compliance team prepares the necessary import documentation.
Q8: Is there a warranty or guarantee on protein activity?
A: We guarantee ≥ 95 % activity as measured by our in‑house liposome‑binding assay. If activity falls below this threshold, we provide a full replacement at no extra charge.
