Protein Sequence Design & Strain Construction
Strain Development and Library Building Services
Hzyme’s expertise in protein sequence design and strain construction is foundational to their CRDMO services. The company excels in creating robust strains tailored for high-yield protein production.

Specializes in Escherichia coli and Pichia Yeast Strain Construction Technology
Escherichia coli (E. coli) and Pichia pastoris are widely used hosts for recombinant protein production due to their well-understood genetics and ability to grow rapidly to high cell densities. Hzyme specializes in constructing these strains, optimizing them for specific protein expressions, ensuring they meet the unique requirements of each project.

Strain Building Library PCB, MCB, WCB
Hzyme maintains a comprehensive strain building library, including:

– PCB (Pre-master Cell Bank)
– MCB (Master Cell Bank)
– WCB (Working Cell Bank)

These libraries ensure that high-quality, consistent, and scalable strains are always available, facilitating rapid project initiation and progression.

Protein Sequence Survey and Design
Hzyme conducts thorough protein sequence surveys and designs tailored sequences that maximize expression and functionality. This involves optimizing codons for the host organism, ensuring proper folding, and reducing the potential for aggregation or degradation.

Optimization of Soluble Expression
Achieving high levels of soluble protein expression is crucial for downstream processing and final product quality. Hzyme employs various strategies, including molecular chaperones, fusion partners, and host strain modifications, to enhance the solubility and yield of target proteins.

Development & Optimization of Downstream Processing
Process Development and Service Optimization
Downstream processing is a critical phase in recombinant protein production. It involves the recovery and purification of the target protein from the host organism. Hzyme’s process development and optimization services ensure that each step, from fermentation to purification, is finely tuned for maximum efficiency and yield.

Development and Optimization of the Fermentation Process
Fermentation is the first step in the production of recombinant proteins. Hzyme optimizes fermentation conditions, including temperature, pH, dissolved oxygen, and nutrient supply, to maximize cell growth and protein expression.

Purification Process Development and Optimization
Purification is essential for obtaining high-purity proteins. Hzyme develops and optimizes purification processes, including chromatography and filtration, to remove impurities and achieve the desired purity levels. Their expertise in various chromatography techniques ensures efficient and scalable purification solutions.

Preparation Process Development and Optimization
Preparation processes, such as refolding of inclusion bodies and buffer exchange, are critical for ensuring the bioactivity and stability of recombinant proteins. Hzyme’s optimization strategies improve these processes, enhancing overall product quality and consistency.

Large-Scale Production and Manufacturing
Flexible Production Capacity Matching
Hzyme offers flexible production capacities to meet the needs of projects of various scales. From small-scale research batches to large-scale commercial production, their facilities and expertise ensure seamless scalability.

Fermentation Amplification and Production
Hzyme’s fermentation capabilities range from 5L to 25,000L, accommodating a wide range of production scales. Their state-of-the-art fermenters and experienced staff ensure high-efficiency fermentation processes, yielding high-quality recombinant proteins.

Purification Amplification and Production
Hzyme’s purification capabilities include various chromatography columns, ranging from D75 to D800. This flexibility allows them to handle large-scale purification processes efficiently, ensuring consistent product quality.

Freeze Production
Lyophilization (freeze-drying) is a critical step for stabilizing and storing proteins. Hzyme’s freeze production capabilities, ranging from 0.2㎡ to 40㎡ lyophilizers, ensure that proteins are preserved with high stability and long shelf life.

Protein Multidimensional Quality Control Platform
Perfect Quality Control Platform
Quality control is paramount in recombinant protein production. Hzyme’s multidimensional quality control platform ensures that every product meets stringent quality standards.

Quality Specification Study

Case Studies
Case 1: Scale Manufacturing of High-Purity and Low-Endotoxin Medicinal Proteins
Case Description: A pharmaceutical company required large quantities of low-cost, high-purity medicinal proteins with endotoxin levels suitable for pharmaceutical use. Hzyme developed a three-step chromatography scheme using their E. coli expression system, achieving an expression level of 20 mg/g wet bacteria, purity over 98%, and endotoxin content below 0.1 EU/mg. This process enabled single-batch production capacities of hundreds of grams, leading to stable delivery of tens of millions of orders.


Case Description: A domestic molecular diagnosis company needed high-purity molecular enzyme raw materials with specific sequence requirements. The customer faced challenges in temperature control processes, scaling up, product stability, and mass production. Hzyme’s collaborative research and process optimization improved the purity to over 95%, enhanced enzyme activity by 1.8 times, and increased single-batch production capacity by more than four times, earning high recognition from the customer.
