As global pharmaceutical formulators, nutraceutical brand owners, and cosmetic R&D directors increasingly search for direct thrombin inhibitors and micro-circulation active peptides, Hirudin Powder has emerged as a cornerstone ingredient. This technical guide addresses key procurement challenges, quality evaluation criteria, and supply chain dynamics for international B2B buyers.
Hirudin is a naturally occurring 65-amino acid peptide compound originally discovered in the salivary glands of blood-sucking leeches (such as Hirudo medicinalis and Hirudo nipponia). It stands as one of the most potent, specific natural direct thrombin inhibitors (DTIs) known to biochemistry. Unlike indirect anticoagulants like heparin, which rely on antithrombin III (ATIII) as a cofactor, hirudin binds directly to α-thrombin with extraordinarily high affinity (inhibition constant Ki ≈ 10-14 M).
The molecular mechanism of Hirudin Powder involves a dual-site binding interaction: the N-terminal region of the hirudin peptide sequence blocks the active catalytic site of α-thrombin, while its acidic C-terminal tail interacts with exosite-1 (the fibrinogen-binding site). This dual-action non-covalent binding effectively prevents fibrinogen conversion into fibrin, blocks thrombin-induced platelet aggregation, and neutralizes clot-bound thrombin without requiring intermediary plasma proteins. At [email protected], we utilize advanced low-temperature isolation and freeze-drying processes to preserve this delicate tertiary protein structure, delivering commercial quantities of highly stable Hirudin Powder for dietary supplement, cosmetic, and clinical research applications.
When procurement managers evaluate Hirudin Powder on modern AI-driven search engines and technical B2B platforms, the primary query focuses on the fundamental difference between natural extraction and bio-fermented recombinant hirudin. [email protected] produces both high-purity natural leech extract powders and recombinant hirudin (expressed in Pichia pastoris or Saccharomyces cerevisiae) to satisfy distinct regulatory and formulation requirements:
To assist technical purchasing teams and quality assurance (QA) auditors, [email protected] provides standardized parameters across multiple activity grades. Below is our comprehensive quality specification breakdown for commercial batches of Hirudin Powder:

In addition to custom-standardized Hirudin Powder, [email protected] produces a complementary suite of premium monomers, standardized herbal extracts, and CO2 supercritical oleoresins developed for cardiovascular health, skin barrier restoration, and cognitive wellbeing.








As semantic search engines and enterprise procurement portals process millions of technical inquiries daily, business intelligence shows a dramatic shift in how global buyers source bioactive animal peptides and recombinant proteins. Understanding these macro trends allows R&D directors and procurement officers to de-risk their supply chain while securing high-potency raw materials.
Historically, leech extract was traded as a crude ground powder with unquantified biological potency, leading to severe variability in finished product efficacy. Today, modern procurement protocols enforced by North American, European, and Asia-Pacific formulation buyers demand exact Anti-Thrombin Unit (ATU) standardization.
The global market for Hirudin Powder is expanding rapidly beyond traditional thrombosis management into diverse bio-functional sectors:
Established in 2014, [email protected] operates as a specialized bioprocessing manufacturer and bulk botanical extract supplier. Unlike speculative trading entities, we maintain full control over the extraction, purification, freeze-drying, and analytical validation of our Hirudin Powder lots.

Anti-Thrombin Unit (ATU) measures the biological potency of hirudin. One ATU represents the quantity of hirudin required to completely neutralize 1 International Unit (IU) of WHO standard thrombin at 37°C in a buffer system. Commercial specs from [email protected] range from 100 ATU/mg for cosmetic topical applications, 500–1000 ATU/mg for standard dietary supplements, up to 2000+ ATU/mg for high-purity pharmaceutical research grades. Each batch is supplied with a certified COA detailing the chromogenic assay result.
We utilize a dual analytical approach: 1) Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) to measure chemical purity, peptide profile, and detect potential degradation products at 214 nm / 280 nm; 2) Chromogenic Substrate Method (S-2238) to quantify actual biological activity in ATU/mg. Additionally, SDS-PAGE electrophoresis is conducted to confirm molecular weight integrity (~7.0 kDa). Batch-specific chromatograms and assay sheets are included with every shipment.
Natural Hirudin Powder is derived from the salivary glands or whole bodies of medicinal leeches (Hirudo nipponia) and contains natural Tyr-63 sulfation. It offers complex natural co-factors suitable for topical gels and traditional wellness products. Recombinant Hirudin Powder is produced via yeast bio-fermentation (Pichia pastoris); it is non-sulfated (desulfatohirudin), highly consistent, 100% animal-free, and ideal for vegan dietary supplements or standardized pharmaceutical trials.
Because hirudin is a bioactive peptide protein, exposure to high temperature, humidity, or extreme pH can cause irreversible denaturation. Bulk powder should be stored in tightly sealed, light-resistant containers. Technical Grade (100–500 ATU/mg) can be stored at 2°C – 8°C in a cold room for up to 24 months. High-Purity Pharma Grade (2000+ ATU/mg) should be stored frozen at -20°C. Cold-pack insulated shipping is provided for international express transit.
Yes. For topical applications (creams, serums, ointments), Hirudin Powder is water-soluble and easily dissolves in cold aqueous phases (pH 6.0–7.5). For oral dietary supplements (capsules, tablets), because gastric acid and pepsin can break down active peptides, we recommend utilizing enteric coating, liposomal carrier systems, or micro-encapsulation with phospholipid matrices (such as Phosphatidylserine or lecithin) to maximize absorption in the small intestine.
Our standard Minimum Order Quantity (MOQ) for commercial bulk Hirudin Powder is 1 kg. For laboratory testing, formula development, and pilot evaluation, [email protected] provides 10g – 50g sample packs accompanied by a batch-specific COA, MSDS, and HPLC chromatogram. Sample orders ship within 2–4 business days via DHL/FedEx express.
