The enzyme-linked immunosorbent assay (ELISA) (/ ɪ ˈ l aɪ z ə /, / ˌ iː ˈ l aɪ z ə /) is a commonly used analytical biochemistry assay, first described by Engvall and Perlmann in 1971. The assay uses a solid-phase type of enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measured.
Congenital FIX deficiency is inherited as an X-linked recessive bleeding disorder (hemophilia B). Severe deficiency standard with FIX potency expressed in international units (IU). Contraindications: Patient receiving anticoagulant therapy.

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. Repeatability across all method/analyser combinations resulted in CVs ranging from 0.8% to 5.4%. The chromogenic assays ROX‐FIX and Biophen FIX:C underestimated rFIXFc for concentrations lower than 0.05 and 0.2 IU/mL, respectively.
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)]).
Eftrenonacog-alfa is a recombinant factor IX-Fc fusion protein increasingly prescribed in hemophilia B patients. We aimed to assess its pharmacodynamics (PD) in real-life setting via FIX activity measurement and thrombin generation assay (TGA). Sixty samples from 15 severe hemophilia B treated patie … In vitro assays are central to the study of cell migration since they allow us to quantify cell migratory capacity under controlled experimental conditions [3,4]. The scratch or wound healing assay is the method of choice for studying cell migration due to the low cost and simplicity of … About Rossix. Rossix develops and manufactures premium quality reagents for hemostasis research, diagnostics and quality control. 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. Rossix is a Swedish developer and manufacturer of reagents for hemostasis research, diagnostics and quality control.

Here, we present an alternative assay, termed immuno-plaque assay (iPA), which utilizes a combination of plaque assay and immunofluorescence techniques. We have extensively optimized the conditions for SARS-CoV-2 infection and demonstrated the great flexibility of iPA detection using several antibodies and dual-probing with two distinct epitope-specific antibodies.

AIM:To evaluate the Hyphen Biomed (Hyphen) and Rossix FIX CSAs on fully automated coagulation analysers and compare them to the FIX one-stage assay (OSA). 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. Repeatability across all method/analyser combinations resulted in CVs ranging from 0.8% to 5.4%. The chromogenic assays ROX‐FIX and Biophen FIX:C underestimated rFIXFc for concentrations lower than 0.05 and 0.2 IU/mL, respectively.

A similar FIX:C assay dependent pattern was observed for the purified rHFIXp spiked at 40, 30 and 20% FIX:C (Fig. 2). In all FIX:C assays tested, rHFIXp was under-recovered to a varying degree from target, with recoveries for the 20% FIX:C samples ranging between -26.5% (STA ®-PTT Automate) and -73.5% (Dade Actin ® FSL) in the aPTT based FIX
FIX:C was analysed in samples and FIXwt controls (C1, C2) using 13 one-stage clotting and 2 chromogenic FIX assays across 38 laboratories in 11 countries. Results: The mean FIX:C result was calculated for all one-stage and chromogenic assays.
