Economical Leech Extract (Hirudo nipponica) - Lyophilized, 500 AT-U per Vial, Stable & Standardized Ingredient for Consistent Cosmetic and Nutraceutical Production

Standard Potency Lyophilized Leech Extract (Hirudo nipponica), 500 AT-U / Vial

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

I. Product Overview

This Standard Potency Lyophilized Leech Extract is a versatile and reliable unit-dose reagent designed for general research and product development. Each vial is standardized to contain a guaranteed 500 Anti-Thrombin Units (AT-U) of natural hirudin, sourced exclusively from authentic Hirudo nipponica. The lyophilized format provides inherent stability, and to ensure optimal long-term preservation of its bioactivity, continuous storage at -20°C or below is required.

II. Key Specifications

III. Core Advantages

1. Balanced Potency for Routine Applications
The 500 AT-U/vial offers a practical and effective dose of bioactive hirudin, making it well-suited for a wide array of routine in-vitro experiments, pilot studies, and initial formulation work where ultra-high concentrations are not necessary, providing cost-effective efficiency.

2. Assured Stability through Frozen Storage
The mandatory -20°C storage protocol is critical to maintain the integrity and stated potency of the lyophilized extract throughout its shelf life. This controlled condition prevents gradual degradation, ensuring reliable and consistent performance in every experiment, from the first vial to the last.

3. Convenience and Reduced Experimental Variability
As a pre-measured, ready-to-reconstitute unit, it eliminates the weighing inaccuracies and potential waste associated with bulk powders. This standardization minimizes preparation error and enhances reproducibility across multiple assays and research batches.

4. Authentic and Traceable Source
Produced within the fully integrated pipeline of Min Kang Bio—from our proprietary breeding base to GMP-guided processing—this product provides guaranteed species authenticity, quality, and full supply chain traceability.

IV. Target Applications

• General Biochemical & Cell-Based Research: Ideal for standard enzyme inhibition assays, studies of thrombin's role in cell culture models, and other fundamental research applications.

• Educational & Teaching Laboratories: A safe, convenient, and standardized reagent for demonstrating principles of enzymology, coagulation pathways, or natural product bioactivity in an academic setting.

• Preliminary Formulation Feasibility Studies: Suitable for initial R&D work on cosmetic serums, topical gels, or oral liquid formulations where a defined amount of active is needed for proof-of-concept.

• Quality Control Testing: Can serve as a consistent reference material for internal QC methods.

V. Packaging, Storage & Handling

• Primary Packaging: Lyophilized powder in a 2 mL sterile glass vial, sealed with a rubber stopper and aluminum cap.

• Storage Condition: Must be stored at -20°C ± 3°C or below. Avoid repeated freeze-thaw cycles.

• Reconstitution: Aseptically add 1.0 mL of cold, appropriate sterile solvent directly into the vial. Gently swirl until the cake is fully dissolved. Do not vortex.

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