SinoBio Biotech's purification development group has developed purification processes for a wide variety of recombinant proteins. Many of these process development projects are undertaken in collaboration with the customer's process development and analytical scientists. A wide range of chromatographic operations have been used for the purification of recombinant proteins (e.g. ion exchange, hydrophobic interaction, affinity, ceramic Hydroxyapatite, metal chelate, gel permeation, etc.).
Scientists in SinoBio Biotech have taken part in 9 protein drugs process development. That is one third of biologics in China protein drug market. In the past three years SinoBio Biotech have established about 400 different proteins manufacture process scale from milligram to tens of gram. About 40 cytokines and tens of enzymes are qualified by well known reagent and cytokine sellers and contract all over the world. Five of them are get into preclinical trials and one of them filed IND.
Points to consider in developing a biopharmaceutical process include: protein purity, scale-up requirements, yield, practical manufacturability and overall cost.
A typical process development protocol for recombinant protein includes:
|1.||Optimization of Expression Systems|
- choice of vector
- choice of cell line and clonal selections
|2.||Optimization of fermentation Conditions|
- available media and supplements
- growth parameters including pH, temperature, O2, etc.
|3.||Development of a purification SOP|
- choice of chromatography steps
- Endotoxin removal
- virus inactivation and clearance
|4.||Confirmed by the customer and technique transfer|
- Original records
- Quality analysis method
- Quality analysis results
- Final SOP of the manufacture process with GLP standard
- Products when required
SinoBio Biotech provide flexible services to meet your diverse requirements. Product development service coupled with SinoBio's contract protein manufacture service can provide you materials you needed with minimal cost esp. when customer just need the protein as raw material and don't want set up their own manufacture facilities.
SinoBio Biotech provide serials quality controls such as SDS-PAGE, HPLC, MS, MS/MS, Amino acid sequencing, endotoxin control to ensure the quality of the final products meet your requirements.
A typical product development procedure includes:
|1.||Discussion with the customers requirements|
- amounts of final products
- quality requirements
- time lines
|2.||Development the products by SinoBio's scientists|
- choose of proper expression systems
- fermentation and purification process development.
- establish quality control method
|3.||Confirmed by the customer and shipment. |
- q.c. methods
- amounts of the products
- quality of the products
|4.||The customer will get. |
- the final products
- quality analysis results
- final report contains
publishable manufacture process
formulation of the products
