Custom Peptide Synthesis

Gallus Immunotech offers a complete custom peptide synthesis service either on its own or in combination with anti-peptide IgY production or affinity-purified anti-peptide production. If you know your peptide sequence(s) and would like a real-time quote, please click here.  You may also print out our peptide order form and fax it to us.  For pricing, please see our Peptide Price List. Perhaps you need help in choosing an immunogenic sequence(s) from your protein.  E-mail us your protein sequence and order the analysis on-line below or by faxing us the order form.  The $100 US charge will be credited to your future peptide purchase.  Selected regions of the protein that would be the best candidate(s) for your custom antibody development in chickens will be suggested.  Please tell us if there are special issues related to the choice of immunogenic sequences.

Product Description More Info Price   Protein Analysis analysis for immunogenic peptides Pro-Ana $ 100.00 USD Peptide Synthesis - Guaranteed Our peptides are guaranteed. Their quality is verified by mass spectral and HPLC analyses which are provided to our customers.  For custom antibody production and affinity purification, it is recommended to synthesize 30 mg peptide.  This is sufficient to immunize 2 hens, make a peptide affinity column and have some left for immunological specificity/blocking experiments.  Recommended peptide purity depends on the peptide’s end use (see below): Peptide purity >75% $23* per residue Immunological grade recomended for polyclonal antibody production/screening purposes HPLC and MS analyses 30 mg Peptide purity >85% $33* per residue recommended for qualitative biochemical analyses, ex. enzyme/ substrate reactions, peptide blocking in qualitative immunological studies or as a ligand for affinity purification HPLC and MS analyses 30 mg Peptide purity >95% $40* per residue recommended for quantitative biochemical and immunological procedures and as immunogen for monoclonal antibody production HPLC and MS analyses 30 mg   *Funds in US Dollars. A wider selection of peptide synthesis choices (purities, quantites and modifications) is available.  For a real-time quote, click here or have a look at our Peptide/Modifications Price List. You may also print out our peptide order form and fax it to us.    Peptide Conjugation Animal immune systems are unable to generate a consistent immune response to small molecules.  To improve the immunogenicity of molecules smaller than 10,000 daltons, it is generally recommended to conjugate the small molecule (peptide or hapten) to a larger carrier protein.  Keyhole limpet hemocyanin (KLH), a large (MW 4.5 x 105 – 1.3 x 107) non-heme protein from the molusc Megathura crenulata, is the most commonly used carrier protein and the one we recommend most often.  Conjugation of your peptide to bovine serum albumin is also available on request. Peptide Conjugation to KLH or BSA 5 mg $240 US To receive an immediate real-time quote for your custom peptide(s) and conjugation(s), please click here.  You may also print out our peptide order form and fax it to us.  For pricing, please see our Peptide Price List.
