Antigen Production

  • Peptide-specific Antibody Production

    We offer the full process: From finding the best peptide sequences for antibody production to ready-to-use purified antibodies. Both polyclonal and monoclonal antibodies can be made this way. 

  • Modified Peptides as Antigen

    Would you like an antibody that specifically recognizes a post-translational modification at a given point in your protein? We can help you achieve this.

  • Recombinant Protein Production

    We offer gene synthesis and transient gene expression for the production of recombinant proteins in eukaryote or prokaryote cells. 

Antigen Production

Protein as an Antigen

Would you like to use a peptide-conjugate, a whole protein or a subunit as antigen? If you don’t have the protein in-house, we can make it for you. We also have extensive experience in making antigens for phospho-specific or acytelation-specific antibody development. We use the following techniques for antigen development:

Peptide synthesis and conjugation

The most popular way of generating an antigen today is by peptide synthesis and conjugation to carrier protein for peptide-specific antibodies. We can help you pin-point areas of the the protein that is suitable for antibody generation, using our peptide design service.

Recombinant protein generation

We can offer gene synthesis and transient gene expression for the production of recombinant proteins in eukaryote or prokaryote cells. 

Fab2 or Fab fragment generation

When making an anti-drug antibody assay,  antibodies specific to the variable regions of your antibody need to be generated. We can assist you with generating and purifying Fab2 or Fab fragments of antibodies. The purified Fab-fragments will be used as antigen to generate antiserum, which in turn can be affinity purified for your assay.
