VisuLize™ Antigen ELISA kits by Affinity Biologicals Ontario are used to determine Factor VIII, IX, XI and TAFI antigens in human plasma samples
For the last 25 years, Affinity Biologicals is renowned worldwide for its scientific range of products used in thrombosis and hemostasis research and diagnostics. The company is also known for producing a comprehensive line of human plasma products that includes immune-depleted, factor-deficient plasmas. The polyclonal antibody based ELISA kits offered by the company deserve special mention in this regard, as each of these kits come with an array of features and can be used in a variety of applications.
The VisuLize™ range of ELISA kits by Affinity are used to determine and analyze Factor VIII, Factor IX, Factor XI and TAFI antigens in human plasma samples by using double antibody ELISA (Enzyme Linked Immuno-Sorbent Assay. Four main products offered in this category are the VisuLize™ Factor VIII Antigen ELISA Kit, VisuLize™ Factor IX Antigen ELISA Kit, VisuLize™ Factor XI Antigen ELISA Kit and VisuLize™ TAFI Antigen ELISA Kit.
Speaking about the individual characteristics of the products, a company representative emphasized on the main features of these kits and their application in diagnosis and characterization of Hemophilia A and B and quantification of Factor VIII, IX and XI in plasma and therapeutic concentrates.
“The VisuLize™ FVIII Antigen Kit measures factor VIII and the VisuLize™ FIX Antigen Kit quantitatively measure factor VIII and IX antigen in human plasma and factor concentrates respectively and are used to check for their congenital deficiency.” He said. “Quantitative (low activity and low antigen) or qualitative (low activity and normal antigen) defect in FIX function results in Christmas Disease or Hemophilia B and the VisuLize™ FIX Antigen Kit is used for the assessment for functional activity of FIX in gene therapy. On the other hand, VisuLize™ FVIII Antigen Kit checks for the functional activity of FVIII, as elevated levels of factor VIII are regarded as a common risk of venous thrombosis.”
Similarly, the VisuLize™ Factor XI Antigen ELISA Kit is used for the quantification of Factor XI – a coagulation protein that is produced in the liver and circulates in plasma in the form of two identical subunits. VisuLize™ TAFI Antigen ELISA kit is used for research purposes as the high plasma concentration of TAFI is considered as a risk factor for thrombosis.
According to the company spokesperson, ELISA kits by Affinity are supplied to leading pharmaceutical companies and laboratories around the world because of the highest level of quality assurance and accuracy they offer. “All four of the polyclonal antibody based ELISA kits offered in our VisuLize™ line are developed after extensive research and are FDA certified to provide our clients the level of quality that they expect of us. We have highly accomplished and specially trained staff on board along with state of the art equipment so that the end product is optimized to perform to its fullest in all kinds of conditions.”
