Formulations
High-Concentration Lyophilized Leech Extract (Hirudo nipponica),
2000 AT-U / Vial
Product Form: Lyophilized Powder in Vial | Research & Formulation
Grade
I. Product Overview
This High-Concentration Lyophilized Leech Extract provides a potent and precisely standardized unit dose for
demanding research and development. Each vial is guaranteed to
contain 2,000 Anti-Thrombin Units (AT-U) of natural hirudin activity, derived exclusively from Hirudo nipponica. Presented in a stable, freeze-dried form, this product is
engineered for reliable performance in critical applications. To
ensure maximum long-term stability and preserve the full
bioactivity of this concentrated peptide, continuous storage at -20°C or below is required.
II. Key Specifications
III. Core Advantages
1. Substantial & Standardized Potency
With 2,000 AT-U per vial, this product delivers a significant dose of bioactive hirudin,
ideal for experiments and formulations that require a high level of
activity without the need to handle and process large amounts of
raw or intermediate materials. The pre-measured format ensures
dosing accuracy.
2. Designed for Stability and Reproducibility
The mandatory -20°C storage condition is integral to the product design, safeguarding the conformational
integrity and activity of the hirudin peptides over extended
periods. This guarantees that the potency stated on the label is
reliably maintained, leading to highly reproducible experimental
and formulation results.
3. Efficiency in Research and Development
This ready-to-use unit eliminates the time, potential error, and
material loss associated with weighing and extracting from bulk
powders. It streamlines workflows in cell-based assays, enzyme inhibition studies, and pilot-scale
formulation, allowing scientists to focus on core research objectives.
4. Traceable Quality from Source
Produced within Min Kang Bio's fully controlled vertical
system—from our proprietary GAP breeding base to GMP-guided
processing—every batch offers guaranteed authenticity, purity, and complete traceability.
IV. Target Applications
Cell Culture & In-Vitro Assays: Provides a consistent, high-potency additive for studies on thrombin-mediated cellular processes, endothelial cell function, or
inflammation models.
Biochemical & Enzymology Research: Ideal as a potent, specific inhibitor in kinetic studies of serine proteases or in the development of related bioassays.
Formulation Prototyping for Topicals/Gels: Serves as an excellent high-activity ingredient for developing concentrated serums, wound care gels, or transdermal delivery
systems.
Reference Material: Suitable as a well-defined, high-potency standard for analytical
method development or quality control procedures.
V. Packaging, Storage & Handling
Primary Packaging: Lyophilized powder in a 5 mL or 10 mL sterile glass vial, sealed with a rubber stopper and aluminum seal.
Storage Condition (Mandatory): Must be stored at -20°C ± 3°C or below immediately upon receipt. Avoid repeated freeze-thaw cycles. For long-term storage over 2
years, -80°C is recommended.
Reconstitution: Use aseptic technique. Reconstitute with an appropriate volume of
cold, sterile solvent (e.g., 0.9% saline or specified buffer) by
gently swirling. Do not vortex vigorously.
Shelf Life: 36 months from the date of manufacture when stored continuously at -20°C or colder.
VI. Company Profile: The Foundation for Reliable Bioactives
The ability to consistently produce this stable, high-potency 2000
AT-U extract stems from the integrated expertise of Jingzhou Min Kang Biotechnology Co., Ltd., the global leader in Hirudo nipponica biotechnology.
Unmatched Scale and Control: We operate the world's largest GAP-certified industrial breeding base for Hirudo nipponica. This scale ensures a sustainable, high-quality supply of raw
materials, which is the fundamental first step in producing
standardized, potent extracts.
Proprietary Stabilization Science: Achieving reliable stability for a 2000 AT-U concentrate requires
specialized knowledge. Our patented lyophilization protocol is optimized to protect the delicate structure of hirudin during
the freeze-drying process and throughout its frozen shelf life,
ensuring the activity you measure is the activity we guarantee.
Commitment to Advancing Science: As a National High-Tech Enterprise, we are dedicated to providing the research and industrial
communities with innovative, high-quality tools that enable
discovery and development.
Disclaimer: This product is a standardized bioactive material intended solely
for research, development, and professional formulation purposes.
It is not for direct consumer use as a finished product. Users are
responsible for compliance with all applicable regulations in their
