What is the typical turnaround time for custom polyclonal antibody production?
Our typical turnaround time is 3 to 4 months for polyclonal antibody productions. This could vary depending on the antigen type and the antibody package choice you have selected.
I am in a rush to get an antibody for my research. Do you offer an express service for your antibody production?
Our default is a 70-day immunization protocol. However, a 42-day express protocol can be requested for certain packages at no extra cost. Please contact us for more information.
Do we need to provide the antigen?
Our packages include the option for you to supply the antigen yourself, or you can make use of our peptide synthesis and protein production services.
How do I select the appropriate antibody production package for my research?
There are two basic starting antigen types: short peptide sequences or full length proteins. Our antibody packages are designed around these two basic types. The selection may be based on your budget and your downstream applications.
Other factors to consider include:
- Signal peptide regions and trans-membrane domains are not suitable for protein antigens, as these regions are generally not available for binding of the resulting antibody. Furthermore, these regions are generally excluded in cases where a recombinant protein is produced for immunization.
- The antibodies produced from a short peptide sequence may behave a little differently from one that is produced from a full length protein, although the affinity should be the same. It's the conformational structure from a full protein that will impart this difference, since a chemically-synthesized peptide will be a linear sequence.
- If you have a wide range of intended downstream applications – including immunofluorescence, immunohistochemistry, functional assays, WBs, and ELISAs – it may be worthwhile to use the protein antigen approach. If you only need this antibody for WBs or ELISAs, it would be more cost-effective to go with a peptide antigen.
How do I design the appropriate peptide candidate for my custom antibody?
We can perform the antigen design for you at no cost. Simply send us the target sequence or accession #, and our expert team will select the appropriate peptide antigens based on your requirements.
Do you offer other host species for the polyclonal antibody service?
Yes, we do. We have a variety of different hosts you may choose from, including mouse, rat, guinea pig, as well as the standard rabbit. Please contact us for more details.
What is the standard polyclonal antibody production immunization protocol?
- Day 0: 1-2 ml pre-immune sera and 1st immunization with CFA
- Day 14: 2nd immunization with CFA
- Day 28: 3rd immunization with IFA
- Day 35: 4th immunization with IFA
- Day 42: 5th immunization with NaCl (0.9 %)
- Day 49: 6th immunization with NaCl (0.9 %)
- Day 56: 7th immunization with NaCl (0.9 %) & serum collected for ELISA testing
- Day 63: 8th immunization with NaCl (0.9 %)
- Day 70: Final bleed (once serum titer reaches 1:8,000 dilution, proceed with serum collection and purification).
