Few words about XEMA

XEMA Co. Ltd. (formerly Xema-Medica) is a private company established 02/93 in Moscow. We started our operations as the contract manufacturers of human antigens; now our company is among world leaders in production of tumor marker antigens. Our broad hybridoma collection enables us to manufacture large quantities of purified monoclonal antibodies for in vitro diagnostic use.

We are proud to maintain a high level of research work focused on several main research topics:
- biochemistry and immunology of human and veterinary tumor markers (CEA, CA125, CA19-9, CA72-4, MUC1, cytokeratins etc);
- immunochemistry of food antigens (especially prolamins of cereals, meat and fish species)
- study of fungal antigens and development of immunoassays for evaluation of fungal contamination of foods and environment;

Since 1997, we have entered a very tough market of finished in vitro diagnostic reagents with the broad panel of EIA kits, including determination of hormones, tumor markers, prenatal and neonatal markers, thyroid autoimmunity markers and infection serology. All our kits are based on an open and simple assay technology - 8x12 microwell breakable strips and photometry at 450 nm. All components are liquid and ready-to-use, addition of samples is monitored by color change of the incubation/dilution buffer. We always try to offer most economical solutions for the markets with restricted budgets.

Besides, our company developed a number of kits for research use in medicine, eg Alveomucin EIA (diagnostics and monitoring of interstitial lung diseases), as well as EIA kits for veterinary use (Progesterone in cow’s milk- Cow pregnancy test), and use in food control, eg Total Fish EIA and Pork EIA (the test for quality control of pasta products).

In 2008, we also launched the immunometric kits based on Time-Resolved Fluoroimmunoassay (TRFIA/DELFIA) principle – PAPP-A and free beta-HCG TRFIA, and rapid lateral flow tests.

Since 2003, our IVD kit production and sale is certified by ISO 9001. In the same year, we built a new modern factory for manufacturing ELISA kits designed in accordance with GMP rules. In the end of 2003, we organized a joint venture with our colleagues from Minsk, Belorussia to manufacture and sell our kits in this region. In October, 2004 we opened our subsidiary in St-Petersburg, Russia. In 2008 we also started our operations in Ukraine with our sister company.

Since 1999, XEMA offers IVD kits and their components for Russian and international markets. We export our production to C.I.S. countries, Germany, Italy, Belgium, China, Israel, Turkey, Iran, Malaysia, Indonesia. Our annual sales in 2009 reached ca 6.5M USD.
