Assistance in Peptide Sequence Selection

PRF&L will select antigenic peptide sequences corresponding to the optimal antigenic domains using the protein sequence that you supply. After consultation with you regarding your project's goals, our expert staff will determine optional domains that are most likely to generate an antibody that will work best your specific application.  Suggested animal host(s) will be determined.  
A detailed report will be provided.
$250 per protein analysis

Custom Peptide Synthesis and Conjugation

Package prices include at least 10mg for sequences up to 20 amino acids and 4mg conjugated to KLH. The peptide must contain a terminal cystine. If peptides do not contain terminal cystine, contact us for pricing. BSA and OVA are also available for conjugation at the same prices.

ELISA - Screening for Titer

Samples run in duplicate and actual titer reported.  Recommended that minimum of two bleeds are tested; the desired sample along with either the preimmune or previous immune bleed.
