Pollen Processing

Preparing raw pollen for use in allergenic extracts.

The Biologics Department collects, sources, identifies, and, in some cases, cultivates raw allergenic source materials such as pollens, as well as foods, danders, insects, hair, feathers, wools, and many more.

Pollens are collected at specific times of the year by experienced collectors and identified by genus and species. When they reach our Biologics Department, we follow meticulous and lengthy processes to prepare them for extraction. The pollens are dried (if needed), weighed, and defatted, with quality assurance measures incorporated into every step. Then they are sent to our Manufacturing Department for extraction.

Stallergenes Greer offers over
150 different pollen extracts.

Mite Facility

Where we cultivate and process mites

Stallergenes Greer cultivates dust mites from special cultures in its own facility, and grows them under controlled conditions to ensure reliable purity. Then they are processed and weighed, with controls in place to monitor quality all along the way. Only then do they move on to our Manufacturing Department.

Our base mite cultures, from which new cultures are grown, have been maintained for over 25 years, helping to provide lot-to-lot consistency.

Our focus is on fungi

The mycology department prepares fungi, and only fungi, for extraction. Unlike allergens obtained from external sources, fungi from Stallergenes Greer are grown entirely in our North Carolina facility from authenticated cultures. They are cultured on special growth media under strictly controlled conditions to ensure purity and lot-to-lot consistency.

The Mycology Department can grow more than 60 different fungal cultures. To assure a long-term supply and safety stock, we maintain stock cultures of our molds, stored as either oil overlays or lyophilized plugs.

Commercial production of extracts

To ensure the highest level of quality, manufacturing is conducted in appropriate ISO class environments that meet FDA cGMP (Current Good Manufacturing Practice) requirements. There, only specially trained individuals who wear appropriate garb may perform the highly technical steps of manufacturing sterile allergenic extracts. First, the raw materials are mixed with an extracting fluid, then centrifuged, filtered, clarified, and sterile filtered. In the next step, using equipment that has been sterilized and depyrogenated, vials are filled aseptically. Finally, the filled vials are meticulously visually inspected prior to finished product labeling.

The highly trained and dedicated employees who work in the Manufacturing Department have an average of 11 years of experience between them, for a combined total of 215 years in the department.

Quality Control Labs

Assuring quality and consistency

This is where extract samples undergo a full range of chemical and microbial analyses, as well as stability testing. Another important function is environmental monitoring, which involves testing samples from surfaces and air during manufacturing to support all conditions meet FDA cGMP standards. Every test is necessary to support the consistency and integrity our products.

The Quality Control Lab performs a minimum of 24 tests, including chemical and microbial assays, on each extract from Stallegenes Greer before being released to customers.
