Step 1: Cross-examine the sequence provided by the customer with the information in multiple databases, such as NCBI.
Step 2: Screen suitable, immunogenic protein or peptide candidates.
Step 3: Compare BLAST searches with genome or protein databases to identify ideal protein or peptide candidates.
Step 4: Perform protein alignments of homologs/orthologs/isoforms.
Step 5: Refer to relevant publications to better understand the 3D structure of the protein and the protein-protein/protein-DNA interaction.
We immunize rabbits, mice, rats, and guinea pigs to generate custom polyclonal antibodies against peptide antigens and protein antigens. Both peptide and protein antigens can be provided by you or prepared by us.
ABclonal's standard protocol for polyclonal antibody is optimized to produce antiserum in the shortest possible time. It is the most affordable option and a popular choice among researchers.
The protocol uses two New Zealand White rabbits that are specific-pathogen-free. Injections are subcutaneous (SQ) as emulsions in Complete Freund's Adjuvant (CFA) or Incomplete Freund's Adjuvant (IFA). We guarantee that the same antigen will be injected into both animals.
