We have obtained a set of monoclonal antibodies against lupin antigen; the pilot versions of immunoassays (cat# K385 Lupin ELISA and respective rapid test cat# X385 XEMAtest Lupin) show the sensitivity better than 5 ppm are soon available for evaluation. The targets of the assay is under determination by WB and MALDI-TOF.10.2017

We have managed to improve considerably the sensitivity of XEMATest Macadamia by switching to another target protein. Now the test is capable to detect 1 ppm of the nut even after high temperature heating (up to 150C). XEMATest Macadamia v2 is available from stock. The target protein is under investigation by WB, we plan to prepare it for direct sequencing due to lack of common library information.

Coming soon! We are glad to introduce a new ELISA for a quantitative detection of CA 242 antigen in human serum/plasma (soon to be launched). CA 242 is a reliable and sensitive marker of pancreatic and colorectal cancer - sensitivity of this test is comparable to that of CA-19.9, while specificity is much better - in pancreatic cancer, it comes to 90%.
