productionEggs may be kept in the fridge for up to 3 months easily and, possibly for up to 6 months .  We would ask that you separate the yolks from the white and pool the yolks that are to be purified BUT PLEASE DO NOT FREEZE THE YOLKS!  Adding 0.05% sodium azide (125 ul 10% sodium azide/25 ml egg yolk) will preserve the yolks so they can be shipped at room temperature.  Otherwise, they should be shipped on ice.  Please ship the yolks the day they are cracked to:

Gallus Immunotech Inc.
6570 First Line West Garafraxa
R.R. #3, Fergus, Ontario
Canada
N1M 2W4

If shipping yolks from outside Canada, please contact us or fax us (519-843-2928) to request an electronic letter to be included with your yolk shipment to expedite custom clearance into Canada.

Included in the cost of purification will be the determination of IgY concentration, vial labeling and a product specification.  We are usually able to return your purified IgY to you within a week of receipt of your yolks.

If you will be requiring our IgY purification services on a regular basis or for a bulk order, please inquire about our wholesale prices.

We also purify IgY from quail, goose, duck or other avian eggs. Please ask us for a quote.

Want to perform your own custom chicken antibody purification?

Compared to the competition:

  • our kit is cheaper to buy (per mg IgY purified)
  • the yield obtained is 50% higher than our major competitor

The antibody purification kit comes with detailed instructions. Furthermore, should you have problems with your kit, we provide technical support on the antibody purification protocol. More about our our IgY antibody purification kit...

IgY, purified from chicken egg yolk and IgG present in mammalian sera contain antibody specificities that are present in the animal's circulation at the time the eggs were formed or at the time the animal was bled. The IgY that you receive from our standard protocol is approximately 90% pure IgY, containing all the IgY specificities that are present in the hen's circulation and transferred to her egg.

The specific activity (percentage of immunoglobulins that is directed against your antigen) of this IgY fraction (or animal serum) depends on the immunogenicity of your antigen and the genetic make-up of the immunized animal. It is reasonable to expect between 2 and 10% specific activity of IgY/IgG from an animal immunized with a protein greater than 50 kilodaltons. Expect less than 1% specific activity to a peptide from an animal immunized with peptide KLH (there will be a much higher specific activity directed to the carrier KLH portion of the immunogen). For many applications, this non-affinity purified antibodiy fraction will work just fine and it is unnecessary to further purify your IgY/IgG. In fact, further purification may result in the loss of your highest avidity antibodies.

However, sometimes, it is necessary to remove the antibodies that are not antigen specific and this is done by making an antigen column to which the whole IgY/IgG fraction is applied. The IgY/IgG you receive is the antigen-specific fraction that is eluted from the column. To make the affinity column, we will need 5 mg protein antigen (in addition to that supplied for immunizations) at a concentration greater than 3 mg/ml.

Gallus Immunotech Inc. specializes in the development and purification of IgY antibodies, primarily in chickens. However, if you have animal sera from which you would like affinity purified antibodies, we would be happy to do this for you.

If you want affinity-purified IgY from 2 hens immunized with a peptide that we synthesize and conjugate to KLH, please see our Affinity Purifed anti-Peptide Combo for special pricing.
Our custom affinity purification service includes:

  • making an affinity column with your antigen or peptide
  • antibody affinity purification of antigen- or peptide-specific IgY (or IgG) from a 0.5 gram purified chicken IgY antibody fraction or 25 ml animal serum sample:

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. If you would like your IgY affinity purified, we need an additional 5 mg protein at a concentration greater than 3 mg/ml to make an affinity column.

Where do you ship your antigen?
Ship your purified immunogen, recombinant protein or peptide conjugate to us at:

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

Industrial Quantities
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. Following our standard immunization protocol (4 immunizations over 40 days), hens receive a booster shot every 70 days to maintain a high titre yolk.

We recommend immunization with, between 0.5 and 2 milligrams of purified or recombinant protein per hen and require 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. If you would like your IgY affinity purified (please see below), we need additional protein at a concentration greater than 3 mg/ml to make an affinity column. The amount of extra protein required depends on the size of the affinity column that will be made. This depends on the amount of affinity IgY that is required.

Do you want us to Affinity Purify your Custom IgY?

The IgY that you receive from our standard protocol is approximately 90% pure IgY, containing all the IgY specificities that are present in the hen's circulation and transferred to her egg.

The specific activity (percentage of IgY that is directed against your antigen) of this IgY fraction depends on the immunogenicity of your antigen and the genetic make-up of the immunized hen. It is reasonable to expect between 2 and 10% specific activity of IgY from a hen immunized with a non-avian protein greater than 50 kilodaltons. Expect less than 1% specific activity to a peptide from a hen immunized with peptide — KLH (there will be a much higher specific activity directed to the carrier KLH portion of the immunogen). For many applications, this IgY will work just fine and it is unnecessary to further purify your IgY. In fact, further purification may result in the loss of your highest avidity antibodies.

However, for most industrial uses, it is often necessary to remove the IgY antibodies that are not antigen specific and this is done by making an "antigen column" to which the whole IgY fraction is applied. The IgY you receive is the antigen-specific IgY that is eluted from the column. The amount of immunogen required to make your affinity column depends on how much affinity purified IgY is needed for your project. Please contact us and we'd be happy to discuss this with you.

Do you want your affinity-purified IgY Antibody Labeled?

Let us label your affinity-purified IgY for you. The most popular labels are horseradish peroxidase (HRP), fluorescein isothiocyanate (FITC), biotin and agarose  but other labels are available. Please contact us to provide a quote for your project.

Cost

For industrial scale projects, we purify 10's of grams to kilogram quantities of IgY. The cost for your project will depend on how much IgY and in what time frame it's required. Please contact us and we'll provide you with a detailed quote.
