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 ROX FIX-A Manufacturer: Diapharma Group, Inc. 950030 This product was recently added by customer request, and is available for your convenience. Factor IXa Activity Assay Kit (Fluorometric) (ab204727) is based on the ability of FIXa to generate FXa. The generated FXa proteolytically cleaves a synthetic substrate and releases a fluorophore, AMC, which can be easily quantified by fluorescence microplate reader. 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).

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.

Results: No relevant interference by concizumab was observed in the aPTT or PT assays (Figure A-B). The presence of 200 ng/mL concizumab did not result in any statistically significant differences in factor activity measurements at any FVIII or FIX concentration using either an OSC or CS assay (Figure C-F).

However, information on their performance characteristics and use in diagnostic haemostasis laboratories remains limited. 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).

Rox Factor IX. Rox Factor IX is a chromogenic kit for determination of Factor IX (FIX) activity in plasma and FIX containing concentrates. CE marked and approved for In Vitro Diagnostic Use in Europe and Australia. Outside Europe Rox Factor IX is available for In Vitro Research Use Only.

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. 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).

This study explores potential chromogenic and one-stage clotting method discrepancies in more detail. Five batches each of rFIX and pdFIX were assayed against the 4th IS FIX concentrate (a pdFIX) by activated partial thromboplastin time (APTT) one-stage clotting assay and specific functional chromogenic assay. 4. One-stage clotting versus chromogenic assays for potency labelling of FIX products • A one-stage clotting assay is the established Ph. Eur. method for potency labelling. • There are 2 chromogenic assays available, but they are less established than the chromogenic assay for FVIII. A similar FIX:C assay dependent pattern was observed for the purified rHFIXp spiked at 40, 30 and 20% FIX:C (Fig. 2).

Its biological half-life is 18 to 24 hours. Congenital FIX deficiency is inherited as an X-linked recessive bleeding disorder (hemophilia B). Severe deficiency Interrupted assay set-up: Assay set-up should be continuous - have all standards and samples prepared appropriately before commencement of the assay: Reagents not at room temperature: Ensure that all reagents are at room temperature before pipetting into the wells unless otherwise instructed in the antibody inserts Adeno-associated virus (AAV)-based gene therapies can restore endogenous factor VIII (FVIII) expression in hemophilia A (HA). AAV vectors typically use a B-domain-deleted FVIII transgene, such as human FVIII-SQ in valoctocogene roxaparvovec (AAV5-FVIII-SQ). This study explores potential chromogenic and one-stage clotting method discrepancies in more detail.

Add To Quote Basket. Description. For determination of Factor IX (FIX) activity in plasma and FIX containing concentrates. FIX is a single chain, vitamin K dependent glycoprotein of about 55 KDa, which is activated by FXIa or tissue factor / FVIIa. 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)]).

Despite case reports and reviews describing the immediate-acting nature of factor IX (FIX) inhibitors, many coagulation laboratories continue to use a traditional prolonged incubation for FIX Bethesda assays.
