How much antigen should you ship us?

We recommend immunization with, between 0.5 and 2 milligrams of purified or recombinant protein per hen and prefer a concentration of at least 2 mg/ml. If possible, please supply us with 4 vials of immunogen (for 4 immunizations), the first vial (for the primary immunization) with twice as much antigen as the others.

Where do you ship your antigen?

Ship your purified immunogen, recombinant protein or peptide KLH conjugate to us at:

Exalpha Biologicals, Inc.
2 Shaker Road, Unit B101
Shirley, MA 01464

Overview

For those customers requiring large scale production of IgY, we can meet your specific requirements. All laboratory work is performed using standard operating procedures to assure the highest quality of your custom product depending on your immunogen, how much IgY is required and over what time-frame, we will design a custom project that will suit your needs.

For bulk quantities of IgY, we usually recommend multiple hen immunizations and the pooling of their eggs for IgY purification.
