High-Potency Leech Extract (Hirudo Nipponica) - Freeze-Dried, 3000 AT-U per Sealed Vial for Stable, High-Activity Skincare & Nutraceutical Applications

High Potency Lyophilized Leech Extract (Hirudo nipponica), 3000 AT-U / Vial

Product Form: Lyophilized Powder in Vial | Professional & Research Grade

I. Product Overview

This High Potency Lyophilized Leech Extract is engineered for applications demanding significant, yet precisely controlled, bioactive concentration. Each vial is standardized to contain a guaranteed 3,000 Anti-Thrombin Units (AT-U) of natural hirudin, sourced from authentic Hirudo nipponica. The freeze-dried format, combined with a mandatory frozen storage protocol (-20°C or below), is specifically designed to ensure the maximum long-term stability and integrity of this highly concentrated peptide, making it an indispensable tool for critical, long-duration research and advanced development projects.

III. Core Advantages

1. Optimized High Potency for Demanding Protocols
The 3,000 AT-U/vial specification provides a substantial bioactive load, ideal for studies requiring high local concentrations or systemic effects in experimental models, while offering a more standardized and convenient alternative to processing bulk raw materials.

2. Precision and Batch Consistency
As a pre-measured unit, it guarantees exact dosing and exceptional reproducibility across experiments or pilot production runs. This eliminates weighing errors of potent powders and ensures reliable outcomes in dose-response studies, bioassay calibration, and formulation scale-up.

3. Maximum Stability through Controlled Cryopreservation
This product's potency is preserved by a strict -20°C frozen storage requirement. This cryogenic condition, backed by our proprietary lyophilization process, minimizes molecular degradation, ensuring the full 3,000 AT-U activity is available throughout the shelf life, which is critical for multi-year research programs and secure inventory management.

4. Guaranteed by Full-Spectrum Quality Control
Produced within Min Kang Bio's vertically integrated system—from our proprietary breeding base to cGMP-aligned processing—every vial offers complete traceability, species authenticity, and assured freedom from adulteration, providing foundational confidence for your high-value work.

IV. Target Applications

• Advanced In-Vivo Pharmacology: Suited for pre-clinical research in thrombosis, ischemia-reperfusion injury, fibrosis, and oncology where high, reproducible doses of a natural thrombin inhibitor are required.

• High-Strength Formulation Development: The ideal candidate for R&D into potent topical therapeutics, injectable depots (research use), or high-dose oral formulations where concentrated active ingredient input is necessary.

• Long-Term Research & Biobanking: Its frozen stability makes it perfect for inclusion in research repositories or for use in extended, multi-phase studies where material consistency over time is paramount.

• Biological Standard for High-Tier Analytics: Can serve as a robust standard for validating high-range analytical methods (e.g., specific ELISA, UPLC-MS) used in quality control or pharmacokinetic studies.

V. Packaging, Storage & Handling

• Primary Packaging: Lyophilized powder in a 10 mL sterile glass vial, sealed with a bromobutyl rubber stopper and aluminum crimp cap.

• Storage Condition (Critical): Must be stored at -20°C ± 5°C or below immediately upon receipt and continuously thereafter. Avoid freeze-thaw cycles.

• Reconstitution: Use aseptic technique. Reconstitute with an appropriate volume of cold solvent to minimize initial thermal stress on the peptides. The product sheet for each batch provides specific guidance.

• Shelf Life: 36 months from the date of manufacture when stored uninterruptedly at -20°C or below.
