PRESS RELEASE – June, 20, 2022 – Apprieu (Grenoble)

Leader in development of high-quality custom antibodies, BIOTEM is boosting expertise in immunoassays and increasing kit production capacity tenfold


Project partly supported by French government through France Relance economic initiative


Apprieu, near Grenoble, France, June 20, 2022 – BIOTEM, a hybrid Contract Research Organization (CRO) and Contract Manufacturing Organization (CMO) focusing on high added-value services in the development/production of custom monoclonal antibodies and immunoassays, today announces the implementation of a new industrial site in Colombe, Isère, located just over a mile (2km) from its current site. This new site will be fully dedicated to immunoassay production, which will enable BIOTEM to improve the quality and quantity of its offering to meet the requirements of the In Vitro Diagnostic Medical Devices (IVDMD) market.

The new 900 m2 (~ 9,600 ft²) facility will complement the company’s 2,000 m2 (~ 21,500 ft²) of antibody production platform already in operation. It will focus specifically on ELISA (Enzyme Linked ImmunoSorbent Assay) and LFIA (Lateral Flow ImmunoAssay) tests, manufacturing them to the highest current standards. The site will be equipped with humidity-controlled dry rooms, an ISO 5 standard room (equivalent to a cleanroom), a biosafety 2 confinement laboratory, cold storage, packaging and assembly facilities, and warehousing. BIOTEM’s boosted capacity will allow it to meet the demand for immunoassays, which has been growing rapidly, particularly against the backdrop of the healthcare situation of recent years.

The company has benefited from a €300k ($314k) grant awarded by the French government as part of its France Relance economic initiative. Together with two loans from its historic banking partners (BNP Paribas and Crédit Agricole Centre-Est), this grant will support BIOTEM in strengthening its position as a domestic producer of biological tests and help to reduce the country’s dependence on suppliers that are either physically or strategically distant, the importance of which was put in stark relief by the covid-19 pandemic.

With this boost to its capacity, BIOTEM has upped its projections and now expects growth of 20–30% over the next three to five years. Alongside these developments, the company is planning to step up recruitment by hiring around 20 new staff in the coming months and intends to double the size of its immunoassay team, also within the next three to five years. BIOTEM is seeking to consolidate its quality assurance and regulatory divisions to extend the scope of support it can offer its customers.
