Haematologic Technologies, Inc. (HTI), is both a manufacturer and service provider that specializes in the blood coagulation system. HTI purifies proteins involved in the coagulation cascade, as well as the regulation of bone metabolism. The HTI product line consists of over 150 highly purified and well-characterized proteins including zymogens, enzymes, cofactors, and inhibitors as well as a complementary line of monoclonal and polyclonal antibodies intended for in-vitro research use. Also available are factor deficient plasmas and customized, blood collection tubes made-to-order for clinical research.
GMP services available include analytical testing for IVIGs (such as thrombin generation assays), analysis & characterization assays for biotherapeutics, stability & release testing as well as host cell protein evaluation.
Immune globulin intravenous (IGIV) drugs are sterilized solutions of antibodies made from human plasma, and are used to treat primary immune deficiency and other immune-related conditions. IGIV drugs have, however, been linked to thrombotic events mediated largely by coagulation factor XI(a), which co-purifies with immune globulin as a contaminant. As a result, IGIV drug manufactures are recommended to routinely test the thrombogenicity of their IGIV product via detection of XI(a) in a specially designed thrombin generation assay (TGA).
Haemtech Biopharma Services (HBS) can develop, validate and perform thrombogenicity assays on your IGIV drug product. In addition, we can develop and manufacture the appropriate control for these assays. Each test method and control is developed specifically for your product using state-of-the-art concepts, techniques, reagents and instrumentation. HBS will then implement the assays by testing your samples in-house in our European Medicines Agency -certified, cGMP testing facility.
With methods to identify and quantify HCPs along with the experience to help remove them from your manufacturing process, we offer an all-under-one-roof solution to your host cell protein challenges.
Methods for HCP detection and quantitation:
1D/2D SDS-PAGE | SEC-HPLC for HMW impurity detection
IEX-HPLC and RP-HPLC for impurity identification | 1D/2D Western blot – for HCPs & product quantitation
Commercial HCP ELISA evaluation and method execution | LC-MS/MS proteomic analysis for HCP identity
LC-MRM targeted quantitative proteomics analysis | Develop, validate, and run ELISAs for specific HCPs in product or process samples
Specialized immunochemical methods for immunogenic HCP identification in cases where patients have developed anti-HCP antibodies |
For Biotherapeutics and IVD/POC reagents
Accelerated and real-time stability studies to determine the shelf-life of your drug product under various temperature and humidity conditions. Lot release testing services when you are ready to go from development to commercialization.
