For assays requiring many plates to be read, this can present a problem if the signal begins to decay before plates are read. For this reason, it is important to make sure the assay has been optimized with the substrate in order to avoid misinterpreting signal-fade in a sample as low antigen abundance.

We are experts in chromogenic assays for coagulation factors and our experience goes back to the development of the first commercial chromogenic assay for Factor VIII in the 1980’s.

Background: Our gene therapy trial featuring AAVS3 FIX-Padua (FLT180a) is targeting FIX-Padua expression levels that functionally cure haemophilia B. Recent data shows that FIX-Padua activity (FIXp:C) assay results can vary by up to 3-fold depending on the assay used. Gene therapy clinical outcomes can vary substantially over a 3-fold FIX:C range emphasizing the need to […]

We are experts in chromogenic assays for coagulation factors and our experience goes back to the development of the first commercial chromogenic assay for Factor VIII in the 1980’s. Reference intervals for Hyphen and Rossix assays were 73 IU/dL to 164 IU/dL and 73 IU/dL to 168 IU/dL, respectively, on the CS2500 analyser; and 84 IU/dL to 165 IU/dL for the Rossix assay on the STA‐R.

Nine laboratories testing the Sobi lot also performed FIX CS assays using one or both of the two commercially available kits, provid-ing 11 CS data sets in total: 8 using the Hyphen Biophen (Hyphen BioMed) and 3 using the Rossix FIX kit (Rossix AB). Good recovery and relatively low interlaboratory variability were observed for both different FIX activity assays. The assays were the STA-Cephascreen OSC with STA-Deﬁcient IX plasma (Diag-nostica Stago, Gennevilliers, France [Stago (F)]), the ROX Factor IX chromogenic assay (Rossix AB, Molndal, Sweden [Rossix (S)]), and the BIOPHEN Fac-€ tor IX chromogenic assay (Hyphen Biomed SAS, Neu-ville-sur-Oise, France [Hyphen (F)]).
