Peptide Antibodies

We are able to produce your custom antibodies from proteins you only know the sequence from. There is no need for protein production or purification. We just need your amino acid sequence and our researchers suggest you peptides that represent your protein. We handle all your data confidentially. The complete service can be done by Davids, including peptide prediction, synthesis, conjugation and immunization. Alternatively you can synthesize your peptide and we perform the conjugation and/or the immunizations.
To improve the antigen presentation the peptides are conjugated covalently to a carrier like KLH, OVA, Thyroglobulin, BSA or other molecules. After the immunization process we recommend an affinity purification to receive monospecific antibodies.

Peptide Predictions

We help you to find peptides that represent your protein (see info box). Take advantage of this free service by writing us an email with your amino acid sequence. All of your data is handled confidentially. We only start the synthesis of your peptide when you confirm one or two peptides for the antibody production.
Our prediction program in combination with our scientists suggest you peptides that represent your protein and that are suitable for the antibody production. These peptides have to be antigenic, soluble and must have good epitopes. For a higher chance to use the peptide that represents your protein in the best way, you can immunize one animal with two different peptides. The chance to use the best peptide is: 70% (1 peptide) to 90% (2 peptides) to 97% (3 peptides).

Peptides represent Protein - Peptide Antibodies

Peptide Synthesis

The peptide production is done with solid phase synthesis. Quality controls are performed with HPLC and MS with each peptide. The purity is about 80% (70 –98%) for the immunizations. If you need a higher purity please ask for this service. The services listed in the table below are optimized for antibody production. Our "All-Inclusive-Service" provides you with every step you need including the peptide synthesis and conjugation. If you need more or less amount of peptides please ask for this service.

Peptide Conjugation

You have the chance to send us your peptide for conjugation. We perform the conjugation you need. We offer the conjugation to KLH, Ovalbumin, BSA, Thyroglobulin or other carriers. We perform the conjugation at the -NH2, -COOH, -SH, -OH or other groups of the amino acids, depending which amino acids are available at the peptide. To enhance the antigenicity we are able to use multiple carriers or multiple conjugation methods. This Mixed Conjugation (P111) is available and includes the peptide synthesis. Our All-Inclusive P101 and P102 includes the peptide synthesis as well.

Peptide Immunization

We start with the immunization as soon as the peptide synthesis and preparation is finished. Please add one of our Custom Polyclonal Antibody Services for: Rabbits, Chicken, Small Rodents (Mice, Rats, Guinea pigs) or our Custom Monoclonal Antibody Services for Mice or Rats to your order.
We recommend an affinity purification for polyclonal antibodies to receive monospecific antibodies from the peptide immunization.

Additional Services

We offer additional services like the preparation of peptides for in vivo cell culture applications. Here the peptide fraction is diluted and the impurities are removed by HPLC. Vaporable substances are removed via lyophilization. In a third step the peptide fraction is diluted in a cell culture compatible buffer like PBS or water and sterile filtered.

Order Process

We keep the order process very simple. For peptide antibodies you can send us your amio acid sequence and we predict the antigenicity, solubility and epitopes. We only start the synthesis when you confirm the peptide(s) via email, PO or FAX. If you want to send us peptides synthesized in your lab, send the peptide to:

Davids Biotechnologie GmbH
Roentgenstrasse 3
93055 Regensburg
Germany

The immunizations usually start the same day the antigen arrives. To fasten up the immunization and/or synthesis process and help us to connect your antigen/sequence with your order, ensure you provide the following information:

  1. Your Peptide/Protein Sequence
  2. Concentration & Buffer Conditions of your Peptide
  3. Our Offer, our order form or your official PO
  4. VAT number (only EU Customers, not German Customers)
