Medicago is a world-leading lectin provider, widely renowned for its superb product quality and one of the highest production capacities in the market, with the ability to deliver up to kilogram scale. We have all the knowledge and resources necessary to keep a wide and dynamic product range, and to develop novel lectin products as new demand arises. We can also provide customized versions of most of our listed standard lectin products, including Biotin and FITC conjugation.
Lectins are found naturally in numerous plant types around the world. Their sugar specificity, including the ability to selectively bind the unique glycoproteins covering the surfaces of viruses and bacteria, make them very useful as ligands in affinity chromatography as well as targeting probes for labelling and histochemistry.
These factors make lectins an essential research substance and production component for vaccines, vaccine adjuvants and many other pharmaceuticals. Given the importance of lectins in e.g. immunological and pharmaceutical research and development, the high product quality delivered by Medicago is of the essence.
Selecting the right raw materials has a strong and direct impact on the quality of the lectin end product. At Medicago, we handle all raw materials ourselves and keep a small number of trusted suppliers to closely monitor and control raw material quality. Processing and preparation of all raw materials used in our production is made by our own personnel at our premises in Uppsala, Sweden.
Besides raw materials, it is in production quality that Medicago truly excels. Our lectins are produced using affinity chromatography. We have managed to gradually optimize this process so that today we can obtain lectins with a very high purity, and with a very high share of active moieties relative to inactive ones.
Protein activity is assayed in-house, and a certificate of protein activity is provided with every delivery as a quality assurance that our products perform as expected. Our product advantages are the result of decades of process fine-tuning – and the reason why we confidently call our products ActiveLectins™.
Preserving product quality all the way to the customer's application is challenging for any lectin supplier. In one of Northern Europe's largest freeze-drying plants, Medicago ActiveLectins™ are produced and delivered in the form of an easily manageable powder. We are therefore able to preserve product quality and simplify transportation, while eliminating the need for sensitive handling of a frozen fluid-based solution.
