Product Specification

Lyophilized Leech Extract (Hirudo nipponica) - Standardized 1000 AT-U/Vial, Stable Freeze-Dried Powder for Cosmetic & Nutraceutical Starter Formulations

Concentrated Lyophilized Leech Extract (Hirudo nipponica), 1000 AT-U / Vial

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

I. Product Overview

This Concentrated Lyophilized Leech Extract offers a robust balance of high potency and practical convenience for extensive research and development workflows. Each vial is standardized to deliver a guaranteed 1,000 Anti-Thrombin Units (AT-U) of natural hirudin, exclusively sourced from Hirudo nipponica. The freeze-dried format ensures excellent stability, while the mandatory storage condition at -20°C or below is critical for preserving the full bioactive integrity and shelf life of this concentrated peptide preparation.

III. Core Advantages

1. Optimized High Potency for Demanding Research
The 1,000 AT-U/vial specification provides a substantial yet manageable dose of bioactive hirudin, making it highly effective for a wide range of in-vitro and in-vivo studies without the handling complexity of ultra-high concentration formats. It strikes an optimal balance between significant biological impact and experimental versatility.

2. Uncompromised Stability through Controlled Storage
The requirement for continuous storage at -20°C is a foundational aspect of our quality guarantee. This condition, coupled with our specialized lyophilization process, minimizes enzymatic or chemical degradation, ensuring that the declared potency remains consistent from the first experiment to the last, even in long-term projects.

3. Enhanced Reproducibility and Workflow Efficiency
As a pre-quantified unit, it eliminates the variability and potential error associated with weighing hygroscopic or electrostatic bioactive powders. This ensures exceptional batch-to-batch and experiment-to-experiment reproducibility, saving valuable time and resources in assay development, screening protocols, and pilot-scale production.

4. Guaranteed Authenticity and Supply Security
Produced within Min Kang Bio's fully vertically integrated system—from our proprietary breeding base to cGMP-aligned processing—this extract comes with irrefutable traceability, species purity, and a commitment to consistent supply, mitigating a key risk in long-term research programs.

IV. Target Applications

• Routine In-Vitro Bioassays: An ideal, reliable source of a potent thrombin inhibitor for routine coagulation tests, platelet aggregation studies, and cell signaling research dependent on thrombin activity.

• Pharmacology & Mechanism of Action Studies: Well-suited for dose-response experiments, IC50 determination, and pre-clinical efficacy models where a proven, natural thrombin antagonist is required.

• Biomaterials & Medical Device Research: Useful in studies evaluating blood-contacting properties of materials or coatings, where localized hirudin activity is beneficial.

• Formulation Starter Material: An excellent candidate for developing and testing stable intermediate concentrates for downstream cosmetic, nutraceutical, or topical therapeutic products.

V. Packaging, Storage & Handling

• Primary Packaging: Lyophilized powder in a 3 mL or 5 mL sterile glass vial, sealed with a bromobutyl rubber stopper and aluminum crimp cap.

• Storage Condition (Critical): Must be stored at -20°C ± 3°C or below immediately upon receipt and continuously throughout its shelf life. Avoid temperature fluctuations.

• Reconstitution & Use: Use aseptic technique. For best results, allow the vial to equilibrate briefly at 2-8°C before adding the recommended volume of cold solvent. Gently swirl or invert to dissolve. Avoid vortexing.

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

VI. Company Profile: The Pillar of Reliability in Bioactive Supply

The consistent delivery of this stable, high-fidelity 1000 AT-U extract is a direct result of the unparalleled expertise and infrastructure of Jingzhou Min Kang Biotechnology Co., Ltd., the definitive global leader in Hirudo nipponica science.
