The above schedule of custom polyclonal antibody development/production is approximate. We can also modify it according to the customer’s need.

Additional 4 weeks is required if the custom polyclonal antibody development/production service requires peptide synthesis, mass spec, KLH conjugation. For custom polyclonal antibody development service in which the immunogen is supplied can be started immediately. 


Protein A : 15-20 mg of purified Antibody
Peptide affinity : 2-3 mg of purified Antibody

Terms and Conditions:

If the immunogen is peptide then it must contain a cysteine for conjugation.

  1. If the immunogen is already conjugated or it’s in gel, kindly provide us ~1 mg of free peptide/purified protein for ELISA.
  2. Recombinant protein and purified protein must be shipped in dry ice.
  3. Kindly provide antigen in soluble form.
  4. For peptide affinity purification customer should provide additional 6 mg peptide.
  5. Biostring Inc. guarantees ELISA positive sera for the immunogen synthesized.
  6. The titre of the antisera depends on the quality of the antigen.
