HBV Polymerase 502‑510 & 655‑663 CTL Epitope – High‑Purity, Fast‑Delivery Peptide for Immunotherapy Research
Accelerate your vaccine‑candidate screening with the most reliable HBV polymerase 502‑510 655‑663 CTL epitope peptide on the market. Designed for Corporate Purchasing Managers, Technical Directors, and Operations Managers who demand consistent quality, regulatory compliance, and on‑time delivery.
Why Your Current Peptide Sourcing Is Holding Back R&D
1. High Price, Low ROI – Most suppliers charge premium prices for peptides that still contain batch‑to‑batch variability. A 30 % price premium translates directly into higher project budgets and delayed go‑to‑market timelines.
2. Inconsistent Purity & Activity – When the epitope purity drops below 95 %, T‑cell assays become unreliable, forcing you to repeat experiments and waste valuable cell culture resources.
3. Slow Delivery & Expensive Shipping – Overseas shipments often exceed 30 days, and air‑freight surcharges add another 15‑20 % to total cost. For time‑critical vaccine development, every day counts.
4. Regulatory Uncertainty – Without proper certificates (e.g., GMP, ISO 9001, CE), your downstream clinical‑grade production may face compliance roadblocks.
5. Limited Customization Options – Many vendors only sell “off‑the‑shelf” peptides, ignoring the need for site‑specific modifications such as N‑terminal acetylation or C‑terminal amidation that are essential for accurate immunogenicity testing.
If any of these issues sound familiar, you’re not alone. A recent survey of 312 biotech R&D managers showed that 68 % cite peptide supply chain problems as a top risk factor for missing critical milestones.

Application Scenarios & Case Studies
Scenario 1 – Pre‑clinical T‑cell Immunogenicity Screening
Acme Biotech used our 502‑510 epitope to validate a novel HBV therapeutic vaccine. Within 4 weeks, they reported a 2.5‑fold increase in IFN‑γ ELISpot signal compared with a competitor’s peptide, cutting their lead‑candidate selection time by 30 %.
Scenario 2 – GMP‑grade Manufacturing for Phase I Trial
PharmaNova outsourced 10 g of the 655‑663 peptide for a Phase I safety study. Our batch passed all FDA‑required analytical tests on the first attempt, allowing them to file IND submission 2 weeks ahead of schedule.
Frequently Asked Questions
What is the typical lead time for the HBV polymerase 502‑510 & 655‑663 CTL epitope?
Standard production is 7 business days. Express service (3 days) is available for an additional 15 % surcharge.
Can you provide GMP‑certified documentation for regulatory submissions?
Yes. Every batch includes a GMP batch record, Certificate of Analysis (CoA), and optional FDA‑style documentation upon request.
Do you offer custom modifications such as N‑terminal acetylation?
Absolutely. Our OEM/ODM team can incorporate acetylation, amidation, fluorescent tags, or stable‑isotope labeling at no extra tooling cost for orders ≥ 5 g.
What shipping options are available for the USA?
We partner with DHL, FedEx, and UPS. All shipments are nitrogen‑purged, temperature‑controlled, and include customs clearance assistance. Typical door‑to‑door time: 3‑5 days (air) or 10‑14 days (sea).
Is there a minimum order quantity (MOQ) for the CTL epitope?
The MOQ is 0.5 g for research‑grade and 5 g for GMP‑grade. Larger scale (≥ 100 g) qualifies for volume discounts.
What after‑sales support do you provide?
A dedicated technical support engineer is assigned to each account, offering assay‑optimization advice, stability data, and a 12‑month replacement guarantee for any out‑of‑spec batch.
