Determination of Tissue Thromboplastin Activity [PDF]

Haemostasis, 2009
The one-stage prothrombin time test for tissue thromboplastin activity was evaluated using the correction method. A strong influence of the intrinsic system was seen depending on the clotting time and the type of tubes. This test was unsuitable for quantitative comparison of thromboplastin activity of different preparations.Subsequently a two-stage ...

Thromboplastin standards

Biologicals, 2010
The Prothrombin Time (PT) test is used for monitoring of treatment with Vitamin K-antagonists (VKA). The result of the PT test should be expressed as the International Normalized Ratio (INR). Calculation of INR is based on the availability of International Standards (IS) for thromboplastin and a calibration model. Calibration of a new PT test system is

Thromboplastin as a Clotting Factor

Thrombosis and Haemostasis, 1971
SummaryThe clotting activity of platelets can be sensitively measured by the prothrombin consumption time using normal platelet-depleted plasma as the assay medium. Such plasma when clotted in a glass tube shows no demonstrable consumption of prothrombin but as platelets are added in increasing amounts, the utilization of prothrombin is increased in an

Thromboplastin Bilbao: Reproducibility and Sensitivity of a Spanish Thromboplastin [PDF]

Pathophysiology of Haemostasis and Thrombosis, 2002
Prothrombin time (PT) is the control test for oral anticoagulant therapy as well as the screening test for defects of the extrinsic pathway of coagulation. Its responsiveness to decreased extrinsic clotting factors depends on the source and type of tissue factor thromboplastin extract. In 1994, a rabbit brain thromboplastin – Thromboplastin Bilbao (TBi)

Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy

Hepatology, EarlyView., 2022
Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...

Canine reference intervals for coagulation markers using the STA Satellite and the STA-R Evolution analyzers [PDF]

, 2010
The aim of the current study was to determine canine reference intervals for prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, and antithrombin (AT) according to international recommendations. The STA Satellite coefficients

A performance evaluation of commercial fibrinogen reference preparations and assays for Clauss and PT-derived fibrinogen [PDF]

, 2002
The wide availability of fibrinogen estimations based on the prothrombin time (PT-Fg) has caused concern about the variability and clinical utility of fibrinogen assays.
