Antibody Project Consulting

Determining which custom antibody service is right for your application is the first step towards initiating project. There are many factors that should be taken into account, including desired antibody quantity, desired antibody applications, and antibody specificity.

Each project type has its own set of advantages and disadvantages. One factor is to determine whether to go with a polyclonal, monoclonal, or single domain antibody. Another factor is the host animal should be used for development of the antibodies. The charts below offer the advantages and disadvantages for both factors.

Advantages & Disadvantages: Projects

  • Unlimited quantity and availability of antibody
  • Lot-to-lot consistency
  • High specificity
  • Quick reproduction of antibody once hybridoma is developed
  • Longer production time
  • Requires a minimum of 4 mgs immunogen
  • Higher cost of development
  • Antibodies less likely to work for multiple applications
  • More difficult if using peptide immunogens
  • Low affinity
  • Quick turnaround
  • Inexpensive
  • High affinity
  • One antibody can work for a variety of applications
  • Requires less than 1mg immunogen
  • Multiple host species, including non-mammalian hosts
  • Quantity available limited by the number of bleeds
  • Lot-to-lot variability in characterization
  • Difficulty to reproduce
  • Chicken
  • Goat
  • Rabbit
  • Guinea Pig
  • Llama
  • Mouse
  • Rat
  • Bovine
  • Sheep
  • Small size, ~15kDa, for enhanced tissue penetration
  • Higher neutralization potential
  • High affinity and specificity
  • Lot-to-lot consistency
  • Requires less than 1mg antigen
  • Stable under extreme temperature and pH
  • Quick reproduction of antibody after development
  • Cost-effectuve large scale production
  • High development cost
  • Limited success binding small antigens (peptides & small molecules)
  • Llama

Advantages & Disadvantages: Species

 ProsConsIdeal Package
