Eggs 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
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.
