Asked Questions

What formulation of source materials should I purchase?

Stallergenes Greer source materials are available in 3 different formulations, each with its own benefits. Most extract manufacturers use powdered raw materials, while in vitro diagnostic manufacturers often prefer lyophilized or freeze-dried extracts. The suitability of materials for a particular use must be determined by the customer.

What is the shelf life of the source materials?

Freeze-dried extracts and materials typically have a shelf life of up to 10 years (5 years for venoms). This means that one lot can often be used over the course of several years, which can reduce lot-to-lot variability. In addition, the shelf life is dependent on your intended use of the material and whether it is stored refrigerated or frozen. The freeze-dried extracts and materials we provide are stored as listed on the Certificate of Analysis (COA).

What quantity of a specific source material should I request?
