Standardized Leech Extract Natural Organic Anti Inflammatory For Daily Skincare

Product Specification

Hirudo Nipponica Extract for Daily Skincare - Standardized 500 AT-U/Vial, Gentle Active Ingredient for Anti-Aging Serums & Barrier Repair Formulations

Entry-Level Lyophilized Leech Extract (Hirudo nipponica), 200 AT-U / Vial

Product Form: Lyophilized Powder in Vial | Entry-Level Research & Screening Grade

I. Product Overview

This Entry-Level Lyophilized Leech Extract provides an accessible, cost-effective entry point into standardized hirudin-based research. Each vial contains a guaranteed, precise dose of 200 Anti-Thrombin Units (AT-U) of natural hirudin, exclusively derived from Hirudo nipponica. In its freeze-dried form, it offers excellent handling convenience and intrinsic stability. Mandatory storage at -20°C or below is required to ensure the long-term preservation of its defined bioactivity, making it a reliable and economical choice for foundational studies and screening applications.

III. Core Advantages

1. Optimized for Cost-Effective Screening & Education
The 200 AT-U/vial is strategically designed for high-volume screening assays, educational laboratory exercises, and preliminary feasibility studies where establishing proof-of-concept or observing a clear biological signal is the primary goal, offering an optimal balance of confirmed activity and affordability.

2. Frozen Stability Ensures Consistent Baseline Performance
The critical -20°C storage condition is engineered to prevent any loss of potency over time, guaranteeing that every vial delivers the full 200 AT-U activity throughout its shelf life. This ensures that experimental baselines remain stable, which is crucial for comparative studies and longitudinal research.

3. Eliminates Low-Dose Weighing Errors
Accurately weighing micro-amounts of potent bioactive powders is a significant source of experimental variance. This pre-measured, unit-dose format completely eliminates weighing inaccuracies, ensuring exceptional reproducibility and data integrity, especially in sensitive assay systems.

4. Authentic, Traceable Foundation for Research
Despite its entry-level positioning, this product is backed by the same rigorous supply chain as our highest-potency offerings. Sourced and produced within Min Kang Bio's vertically integrated system, it provides guaranteed species authenticity and full traceability, a key differentiator from non-standardized market alternatives.

IV. Target Applications

• High-Throughput & Preliminary Screening: The ideal reagent for initial bioactivity screens where numerous samples are tested against thrombin-dependent pathways, providing a consistent and affordable active control or inhibitor.

• Academic & Teaching Laboratories: A perfect, safe tool for university courses to demonstrate principles of enzymatic inhibition, natural product biochemistry, and standardized bioassay techniques.

• Dilution Series & Method Development: Excellent for creating precise standard curves in analytical methods (e.g., ELISA development) or for establishing dilution gradients in dose-finding studies.

• Low-Dose Formulation Prototyping: Suitable for early-stage R&D on products where a lower concentration of hirudin is intended, such as in certain cosmetic bases or general wellness supplements.

V. Packaging, Storage & Handling

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

• Storage Condition: Must be stored at -20°C ± 3°C or below. Stability is not guaranteed under other conditions. Avoid repeated freeze-thaw cycles.

• Reconstitution: Aseptically add 1.0 mL of the appropriate cold, sterile solvent. Allow the vial to stand for a few minutes, then gently swirl until completely dissolved.

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

VI. Company Profile: The Unmatched Authority in Leech Bioactives

The ability to offer a consistently stable, entry-level product like this 200 AT-U extract is a direct reflection of the scale, science, and standards set by Jingzhou Min Kang Biotechnology Co., Ltd., the definitive global leader in Hirudo nipponica biotechnology.

1. Unrivaled Vertical Integration from Source to Science
We are not a processor of commodities; we are the originators of the supply. We operate the world's largest and only fully scaled, GAP-certified industrial breeding base for Hirudo nipponica. This complete control, from genetic selection through breeding, harvesting, and primary processing, is the non-negotiable foundation that allows us to guarantee the authenticity, purity, and batch-to-batch consistency of every product, at any potency level.

2. Core Patent Technology Focused on Activity Preservation
Our proprietary low-temperature extraction and stabilization platform (exemplified by patents such as CN107510705B) is engineered for one purpose: to maximize the recovery and long-term stability of native hirudin and its co-active peptides. This technology is why we can confidently mandate -20°C storage and provide a 36-month shelf-life guarantee, transforming a delicate bioactive into a reliable research tool.

3. Quality Certified by the Highest Standards
Our commitment to quality is institutionalized. Our breeding and production adhere to the National Good Agricultural Practice (GAP) guidelines for Chinese Medicinal Materials and our facilities operate under stringent internal quality protocols that meet international standards, providing our partners with unparalleled confidence.

4. The Recognized Industry Leader
Our expertise shapes the industry. As a provincially recognized high-tech enterprise and an active participant in drafting industry technical standards, we are not just following best practices—we are defining them. Our extracts are the benchmark for quality in both academic research and industrial applications.
