Shipping Instructions for Antigens

We recommend formulation, packaging and shipping of antigens as follows:

• Formulation
  
  Antigens should be formulated to maintain the stability of the antigen and be non-toxic to animals. When possible, we recommend a sterile-filtered 1 mg/ml solution of antigen in phosphate-buffered saline with a pH close to 7. Antigen solutions must not contain reagents that are toxic to animals (preservatives, strong reducing agents, etc.) Avoid the use of amine containing buffers such as Tris that may interfere with conjugation methods. Please contact Technical Services for questions regarding the suitability of your antigen formulation.

• Quantity
  
  Consult the Monoclonal Solutions or Polyclonal Solutions program information sheets to determine the quantity of antigen needed for the planned service. We recommend that you send us the entire required quantity of antigen at the beginning of the service.

• Shipping
  
  Ship under conditions known to maintain the stability of the protein. If conditions are unknown, place in an insulated container along with either frozen gel packs for refrigerated antigens or dry ice for frozen antigens. We recommend insulated containers with at least 1/2 inch thick walls and sufficient coolant to hold temperature for 72 hours .

Always ship by courier or overnight express service.

Ship early in the week and allow for 1 extra day to reach us.

FAX or E-mail a copy of the Airbill or the Airbill number to us so that we will know to expect the shipment.

Include the Polyclonal Solutions Order Form with your shipment.
