Interferon Therapy Development for GI and Liver Disease

Expert advice: We can help you choose the most suitable host organism based on your specific IFN requirements, such as E. coli and P. pastoris, considering factors such as glycosylation, expression levels, and cost.

Strain optimization: We can engineer host strains to enhance protein expression, stability, and yield using techniques such as gene optimization, promoter selection, and codon usage optimization.

Vector construction: We can design and construct expression vectors tailored to your specific IFN and host system, incorporating appropriate promoters, selection markers, and protein tags for purification.

Process optimization: We can optimize the fermentation conditions for optimal IFN production, including media composition, temperature, pH, and aeration.

Purification Strategies: We can develop and implement robust purification strategies to isolate your IFN from the host cell lysate, using techniques such as affinity chromatography, ion exchange chromatography, and size exclusion chromatography.

Quality control: We can perform comprehensive characterization of the purified IFN, including purity analysis, activity assays, and structural analysis to ensure that it meets your specifications.

Alternative purification methods: We can explore and implement alternative purification techniques, such as aqueous two-phase systems or immunomagnetic microspheres, to potentially reduce costs and enhance efficiency.

Stabilized formulation: Our formulations enhance the stability and solubility of interferon through the use of excipients such as sugars, salts, amino acids, and surfactants.

Chemical conjugation and genetic engineering: To improve the enterohepatic circulation of interferon to extend its half-life, we can fuse interferon to protein moieties such as HSA using chemical conjugation techniques such as PEGylation and genetic engineering.

Advanced drug delivery systems: We can help customers develop polymer nanocarriers, lipid-based nanocarriers, dendrimers and hydrogels to deliver interferon, aiming to improve the stability and targeting of interferon in the gastrointestinal tract and liver.

Cell culture studies: Utilizing cell lines related to the target disease (e.g., hepatocytes, liver cancer cells, immune cells), we assess the direct effect of interferons on cell viability, proliferation, apoptosis, and immune response modulation.

Viral inhibition assays: Measuring the ability of interferon to inhibit viral replication, particularly in cases of hepatitis B or C infections.

Cytokine profiling: Analyzing cytokine levels in cell culture supernatants or serum samples to understand the immunomodulatory effects of interferon, including its role in inflammation regulation and immune cell activation.

Animal models: Employing animal models (e.g., mice, rats, non-human primates) of related diseases (e.g., viral hepatitis, liver cancer xenografts), we help customers quantify the response to interferon therapy and track disease progression by evaluating parameters such as viral load and tumor size.
