Clongene has developed a large-scale recombinant antibody production (to kg) service, providing customers with recombinant antibodies in the amount of gram to kilogram. Clongene designs the protocol according to the scale specified by the customer, optimizes the sequence design, culture protocol, transfection method and cell line construction protocol to meet customer’s specific needs, and guarantees the delivery of the antibody of the expression amount and quality of customer's choice.
| Service Step | Service Description | Timeline | Deliverable |
|---|---|---|---|
Gene synthesis and subclone (Customers can provide antibody sequences or plasmid as starting material) | - Codon optimization and gene synthesis - Subcloning into an expression vector - Plasmid amplification and preparation | 1-2 weeks | - Purified proteins - CoA |
| Small scale pilot expression and purification | - Transfection of mammalian cells - Small scale pilot expression and purification - QC analysis | 2-3 weeks | |
| Large-scale production (up to 250L) | - Large-scale plasmid preparation - Transient transfection and purification - QC analysis | 5-8 weeks |
The recombinant antibody was produced on a large scale by a 250L bioreactor, the SDS-PAGE and SEC-HPLC analysis results were shown in Figure 1 and Figure 2.
