High quality raw material for IVD manufacturing industry

Recombinant Antigens for IVD of Infectious Diseases

Rekom Biotech has a wide portfolio of recombinant antigens for human and animal infectious diseases in the fields of virology, bacteriology, parasitology and mycology.

Some of our recombinant antigens are pre-validate by ELISA and Western Blot assays with positive specimen sera. We also conjugate our antigens with biotin and peroxidase (HRP) to perform capture and DAS assays as an internal quality control. We are open to adjust the recombinant antigen to your particular needs regarding: purity, concentration, buffer conditions, pH, absence or presence of specific aditives, etc., according to the IVD platform you are using with these recombinant antigens. Trust in our technical team, they will find the perfect antigen option for your system.

STORAGE

Recombinant antigen is shipped with dry ice. Upon arrival, 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.

DEFROST

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

MANIPULATION

Before making test dilutions and after the protein 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 recombinant antigens are expressed in non-pathogenic E. coli and bacterial integrity is destroyed during purification, the antigen preparation should be handled as potentially infectious.
