High quality raw material for IVD manufacturing industry

Bio-markers for IVD manufacturing industry

Rekom Biotech has a wide portfolio of bio-markers for IVD manufacturing industry aimed at the identification of diagnosis of infectious diseases and allergies.

At Rekom Biotech we have specialized in the design and production of next-generation bio-markers: chimeras or multi-epitopes bio-markers which have improved their antigenic properties such as sensitivity and specificity.

Our last line of products are conjugated "ready-to-use" bio-markers, which can be used with multiple objectives: plate orientation, nanoparticle and gold binding, as detectors in immunocapture and immunometric formats, etc. In addition, formats such as ELISA-capture or ELISA-DAS can be used directly to reveal the IVD test.

Focused on reducing complexity of logistics and shipping costs, we lyophilize all our products. This significantly reduces the cost of transport, which also does not require dry ice anymore, and facilitates the entry of our product to a greater number of countries, without the need for intermediaries.

Our bio-markers are provided for research and commercial use in vitro: not for human in vivo or therapeutic use.

The bio-marker can be shipped with dry ice or lyophilized. Upon arrival (if liquid), or after reconstitution (if lyophilized), it should be aliquoted in order to avoid repeated freezing and thawing cycles and stored at -20oC to -80oC. Proteins should be maintained frozen at high concentrations.


In order to defrost the protein, maintain the aliquot at 25oC without shaking to avoid aggregation.


Before making test dilutions and after the bio-marker has been defrosted, it is recommended to remove possible protein aggregates by centrifuging the stock solution, avoiding alterations in the immobilisation of the biomolecule to the solid surface.

During shipment, small volumes of product will occasionally become entrapped in the seal of the product vial. For products with volumes of 200 µl or less, we recommend tapping the vial on a hard surface or briefly centrifuging the vial in a tabletop centrifuge to dislodge any liquid in the containers cap. Although bio-markers are expressed in non-pathogenic E. coli and P. pastoris and bacterial integrity is destroyed during purification, the protein preparation should be handled as potentially infectious.
