Our products are manufactured at modern, state-of-the-art facilities by qualified staff. Product quality is assured through a strictly controlled development process and monitoring of the manufacturing workflow by defined in-process controls. In addition to the testing of raw materials, each step of the production process is closely monitored to confirm compliance with established specifications.
Finished goods – always produced according to documented procedures (SOPs) – undergo a rigorous series of tests in our quality control lab. Each lot is subjected to various biochemical and immunological analyses to assure conformance to our strict product specifications before it can be released.
The goal of these extensive inspections is to ensure lot-to-lot conformance, which guarantees consistent results for our customers. This reduces their development times and efforts. Typical examples of lot-to-lot consistency can be seen by SDS-PAGE + Western Blot or ELISA of DIARECT autoimmune antigens (see adjacent charts).
