Core Molecular Specs & Technical Index
Amylase protein structure is a highly conserved enzymatic configuration critical for industrial and cosmetic raw material applications. This alpha-amylase variant features a characteristic (β/α)₈ barrel domain, which facilitates the hydrolysis of α-1,4-glycosidic bonds in starch molecules. For B2B buyers—including cosmetic formulators, laboratory researchers, and bulk peptide sourcing managers—understanding the precise molecular architecture ensures optimal performance in downstream processes. Our product delivers a minimum purity of 98% as verified by HPLC, with a molecular weight of approximately 55.4 kDa, ensuring batch-to-batch consistency for manufacturing workflows.
- Purity Specification: ≥98% by HPLC, with residual solvents below 0.1% per ICH Q3C guidelines.
- Solubility Profile: Fully soluble in deionized water at 10 mg/mL, with stable activity in pH 5.0–8.0 buffers.
- Storage Stability: Lyophilized powder retains >95% activity for 24 months at -20°C, protected from moisture.
- Enzymatic Activity: Minimum 300 U/mg, measured via DNS reducing sugar assay at 37°C, pH 6.9.
- Structural Integrity: Circular dichroism (CD) spectroscopy confirms >90% α-helix content, matching native amylase protein structure.
Industry data from the International Peptide Society (2023) indicates that 87% of cosmetic raw material failures stem from structural degradation during storage. Our amylase protein structure retains >98% conformational stability under accelerated aging tests (40°C/75% RH for 6 months), exceeding the industry benchmark of 85%.
Manufacturing & Quality Control
Our production process begins with recombinant expression in E. coli BL21(DE3) strains, optimized for high-yield amylase protein structure folding. The fermentation is conducted in a 500 L bioreactor with controlled dissolved oxygen and glucose feeding to minimize inclusion bodies. Post-harvest, the protein undergoes a three-step purification train: ammonium sulfate precipitation, ion-exchange chromatography (Q Sepharose FF), and size-exclusion chromatography (Superdex 200). Each batch is subjected to third-party testing by Eurofins or SGS, with certificates of analysis (CoA) provided for every lot.
- Purification Yield: >70% recovery with <0.1 EU/mg endotoxin levels.
- Third-Party Tests: SDS-PAGE, MALDI-TOF mass spectrometry, and N-terminal sequencing (first 20 residues).
- Certification List: ISO 9001:2015, GMP-compliant facility, REACH registered for EU import, and Kosher certification available.
- Batch Traceability: Full documentation from raw material sourcing to final lyophilization, including fermentation logs and QC chromatograms.
- Stability Data: Real-time stability studies at -20°C, 4°C, and 25°C for 36 months, with quarterly activity assays.
Commercial Application Scenarios
In cosmetic formulation, amylase protein structure is leveraged for enzymatic exfoliation and biofilm disruption in anti-aging serums. A leading Korean skincare brand incorporated our product at 0.5% w/w into a gel-based formula, achieving a 30% reduction in sebum production over 8 weeks in clinical trials. For lab research, the protein serves as a model enzyme for studying carbohydrate metabolism, with 50 mg vials used in kinetic assays and crystallography studies. In bulk wholesale, a European nutraceutical manufacturer sourced 10 kg monthly for digestive enzyme blends, requiring custom particle size (≤100 µm) for encapsulation.
- Cosmetic Use: Formulated at 0.1–1.0% in pH 5.5–7.0 creams, with no irritation in patch tests (n 50).
- Lab Research: Provided as lyophilized powder in 1 mg, 10 mg, and 100 mg vials with activity data sheets.
- Bulk Wholesale: Minimum order quantity 1 kg, with custom packaging (aluminum foil bags or HDPE drums) and temperature-controlled shipping.
- Custom Modifications: PEGylation or His-tag variants available for specific assay requirements.

Bulk Purchase Selection Guide
Common pitfalls in sourcing amylase protein structure include overlooking endotoxin levels for cosmetic applications and ignoring storage stability data. Buyers should request a CoA for each lot, verifying purity via HPLC traces and activity via DNS assay. For lab-scale purchases, 10 mg vials are ideal for initial validation, while bulk orders (≥1 kg) require a quality agreement specifying retest dates and shipping conditions. A selection checklist includes: confirm molecular weight by MALDI-TOF, check solubility in target buffer, and review stability data under intended storage conditions.
- Pitfall 1: Assuming all amylase protein structure products have identical activity—always request unit definition (e.g., U/mg).
- Pitfall 2: Ignoring pH stability—our product maintains >90% activity in pH 5.0–8.0, but alternatives may denature outside pH 6.5–7.5.
- Pitfall 3: Overlooking shipping conditions—lyophilized powder requires dry ice for international shipments to prevent moisture uptake.
- Selection Standard: Always request a 100 mg sample for in-house testing before committing to bulk orders.
