For our IVD manufacturer customers that want to develop a new assay and cannot find the right raw material, we offer a complete Pack for Antigen Expression and Purification which includes design of the recombinant antigen, codon optimisation, gene fragment clonation and expression, growing scaling-up, purification to homogenety and immunological studies in Western Blot and ELISA.
We like to work closely with our customers to understand their problems and provide them with products totally adapted to their needs.
Study of the gene sequence, theoretical sequence analysis, selection of a heterologous expression system, selection of the optimal expression vector, design of the specic primers, codon optimization of the gene, etc.
Amplication by PCR, clone of the target DNA in a selected expression vector, validation of the selected clone by sequencing and restriction analysis
Screening and selection of induction conditions, possibility of dierent fusion tags, solubility and expression optimization MCB and WCB stocks production, etc.
Obtention of the seed by shaker and scale-up in bio-fermenter
Design of the complete DSP, purication of the target antigen by using dierent chromatographic procedures, ultraltration, diafiltration, optimization of the formulation buffer, etc.
Purity, integrity, macroaggregation and microaggregation analysis, stability, western blot analysis, ELISA assay, etc.
