Polyclonal Antibody Production Protocol
 
Protocol Definition:
 
Subject:
 
New Zealand White Rabbits
Adjuvant:
 
Complete Freund’s Adjuvant (CFA) initially, followed by incomplete
Freund’s Adjuvant (IFA) for all subsequent injections.
Immunogen:
 
Typically, proteins and conjugated peptides. Amount of immunogen used
for each immunization is 0.5 mg /per rabbit /per injection.
Procedure:
 
The immunogen is diluted to one mL with sterile saline and combined
with one mL of the appropriate adjuvant. The antigen and adjuvant are
mixed thoroughly to form a stable emulsion which is injected
subcutaneously and provides enhanced immune response from the
sustained presence of the immunogen.
Bleeds:
 
Blood is collected from the central ear artery with a 19 gauge needle and
allowed to clot and retract at 37°C overnight. The clotted blood is then
refrigerated for 24 hours before the serum is decanted and clarified by
centrifugation at 2500 rpm for 20 minutes.
Schedule:
 
Day 1
Bleed 25 mL (yields 10 mL pre-immune serum). 1st Immunize with antigen in CFA.
Day 20
2nd Immunize with antigen in IFA.
Day 40
3rd Immunize with antigen in IFA.
Day 50
Test Bleed 10 mL for ELISA screen(internal quality control only, not provide to client).
Day 60
4th Immunize with antigen in IFA.
Day 70
Final Total Bleed 50 mL from Each Rabbit.
 
 
Phosphospecific Antibody Affinity Purification:
 
Genemed Synthesis offers phosphospecific antibody affinity purification which includes:
  1. Phosphospecific peptide synthesis (up to 15 amino acids) -- 10 mg used for phosphospecific epitope affinity purification, 10 mg used for antibody production, and 10 mg delivered to client
  2. 10 mg non-phosphospecific peptide (up to 15 amino acids) used for affinity depletion
  3. Immunization of 2 rabbits
  4. Phosphospecific and non-phosphospecific peptide ELISA titration of antibody for final bleeds
  5. Pre-immune sample of serum (5 mL/each rabbit) and anti-serum (100 mL total) from two rabbits
  6. Affinity purification of serum
  7. Shipment of purified phosphospecific antibody which does not cross-react with
    non-phosphospecific peptides (confirmed by ELISA)
