Prothrombin Time Assays

 

Thromboplastin-LI Reagent Kit

  • ALT NAME
Cat. No. Item
5248 Thromboplastin-LI Kit, 250 tests, 10 x 5 mL
5249 Thromboplastin-LI Kit, 500 tests, 10 x 10 mL

Thromboplastin-LI is a stable liquid, ready for use. With a low ISI assignment less than 1.50, this reagent offers reliable sensitivity to liver disease, depression of Vitamin K dependent factors, and coumarin-induced coagulation, even in the presence of high-dose heparin therapy. Open reagent is stable 14 days at 2-8-C.

 


 

aPPT-SA Reagent with Soluble Ellagic Acid Activator

  • ALT NAME
Cat. No. Item
5388 aPTT-SA Reagent Kit, 250 tests
- Ellagic Acid Activated Reagent, 5 x 5 mL
- 0.025 M Calcium Chloride, 5 x 5 mL
5389 aPTT-SA Reagent Kit, 500 tests
- Ellagic Acid Activated Reagent, 5 x 10 mL
- 0.025 M Calcium Chloride, 5 x 10 mL
5387 aPTT-SA Reagent, 1000 tests, 10 x 10 mL
5386 0.025 M Calcium Chloride, 1000 tests, 10 x 10 mL

aPTT-SA Reagent uses a soluble ellagic acid activator to provide a more optically clear reagent, an important consideration for automated analyzers with sensitive photo-optical detectors. Ellagic acid reagents also offer excellent precision and sensitivity. aPTT-SA reagent is a stabilized liquid available in three convenient kit sizes.

 

 



Factor Deficient Substrates / Owren's Veronal Buffer

Congenital Factor Deficient Substrate Plasmas

  • ALT NAME
Cat. No. Item
5190 Factor II Deficient Substrate, 10 x 1 mL
5191 Factor V Deficient Substrate, 10 x 1 mL
5192 Factor VII Deficient Substrate, 10 x 1 mL
5193 Factor VIII Deficient Substrate, 10 x 1 mL
5194 Factor IX Deficient Substrate, 10 x 1 mL
5195 Factor X Deficient Substrate, 10 x 1 mL
5196 Factor XI Deficient Substrate, 10 x 1 mL
5197 Factor XII Deficient Substrate, 10 x 1 mL

For use in Factor Assays, these plasmas are obtained from human congenitally deficient donors (Factor II includes bovine plasma) and have less than 1% residual factor activity.

 

Owren's Veronel Buffer

  • ALT NAME
Cat. No. Item
5375 Owren's Veronel Buffer, 10 x 25 mL

Owren's Veronal Buffer is used as a diluent in preparing patient sample dilutions for Factor Assays and Fibrinogen Assays.

 

 

 


Fibrinogen and Thrombin Time Assays

Fibrinogen Assay Kit

  • ALT NAME
Cat. No. Item
5376 Fibrinogen Assay Kit, 100 tests
- Thrombin Reagent, 5 x 2 mL
- Fibrinogen Calibrator, 2 x 1 mL
- Owren's Veronal Buffer, 2 x 25 mL
- Fibrinogen Assay Graph Paper, 1 sheet
5374 Thrombin Reagent, 200 tests, 10 x 2 mL
5379 Fibrinogen Calibrator, 10 x 1 mL

The Fibrinogen Assay kit is for automated, semi-automated and manual quantitation of fibrinogen in plasma. The kit uses a relatively high working concentration of thrombin (100 NIH units/mL) and low fibrinogen concentration to minimize effects of heparin and FDPs. Reagents and calibrator are also available as individual items.

 

Helena Thrombin Clotting Time (TCT) Reagent

  • ALT NAME
Cat. No. Item
5377 Thrombin Time Reagent, 250 tests, 10 x 5 mL

Helena's TCT assay uses a low concentration of thrombin (3 NIH units/mL) with undiluted plasma. It is sensitive to fibrinogen levels below 70 mg/dL. The reagent is ideal for automated, semi-automated and manual instruments.
