protein c protein s rocket plates
The Protein C Rocket procedure is for quantitation of plasma Protein C Antigen by Laurell Rocket electrophoresis. The plate contains antiserum specific for Protein C. After electrophoresis, a rocket-shaped precipitin pattern forms along the axis of migration. The length of the rocket is proportional to antigen concentration.

The Protein S Rocket procedure is for quantitation of plasma Protein S antigen (either total or free) by Laurell Rocket electrophoresis. The plate contains antiserum specific for Protein S. After electrophoresis, a rocket-shaped precipitin pattern forms along the axis of migration. The length of the rocket is proportional to antigen concentration. Free Protein S can be assayed on the same plate as total Protein S by treating the sample with Free Protein S Reagent (Cat. No. 5363).

Cat. No. Item
5363 Free Protein S Reagent, 5 x 2 mL

The reagent is a solution of PEG used to separate free Protein S from bound Protein S.   For use with the Protein S Antigen Rocket Plates.

von Willebrand Factor Antigen (vWF:Ag) Rocket Plates
Accurate quantitative measurement of vWF:Ag in human plasma aids in differentiating von Willebrand Disease from Hemophilia A and in detecting carriers of Hemophilia A. Quantitation of vWF:Ag by Laurell rocket electro-immunodiffusion combines the specificity of immunochemistry with the speed of electrophoresis. The kit contains 5 plates with antiserum to human von Willebrand antigen incorporated into agarose.

Cat. No. Item
5362 Rocket Stain, 1 x 0.9 g
Rocket Stain
The stain is for use with Helena Rocket Plates (vWF:Ag, Protein C and Protein S). The stain is Coomassie Brilliant Blue, a very sensitive stain, making rocket measurement and quantitation simple and precise. Powder is dissolved in methanol, deionized water and glacial acetic acid to make 1 liter of stain solution.

5358 Tris-Tricine Buffer, 10 x 14.1 g
5016 Electra B1 Buffer, 10/pkg
Buffers for Rocket Assays
Buffers for Rocket Assays

Tris-tricine Buffer is used in the Protein C and Protein S rocket electroimmunoassay methods. Electra B1 Buffer is used in the von Willebrand Factor Antigen rocket electroimmunoassay

Cat. No. Item
5227 Rocket Antigen Report Forms, 1 pad of 100
These report forms are designed for use with the von Willebrand Factor, Protein C and Protein S Antigen Rocket Methods. They provide a complete record of the reference curve and the patient results.

9326 Plasminogen QUIPlate Kit
 • Plasminogen QUIPlates, 3 x 19 wells/plate
 • PMG standards (2.5, 5, 10 and 20 mg/dL), 1 set
 • Graph paper, 1 sheet
Plasminogen QUIPlate Kit
Plasminogen QUIPlate Kit
The kit is designed for the quantitation of plasminogen by radial immunodiffusion. Plasminogen, part of the in-vivo system for dissolution of fibrin in blood clots, is a critical factor in hemostasis. Each QUIPlate Kit has been carefully standardized for reproducibility and accuracy. Crisp, well-defined precipitin rings can be read at 24 hours.

Cat. No. Item
5200 Antithrombin III QUIPlate Kit
 • AT III QUIPlates, 3 x 19 wells/plate
 • AT III standards (3, 6, and 12 mg/dL), 1 set
 • Graph paper, 1 sheet
Antithrombin III QUIPlate Kit
Antithrombin III QUIPlate Kit
The kit is for quantitation of human Antithrombin III (AT III) by radial immunodiffusion. AT III levels have been shown to be decreased in post-operative patients, patients undergoing cardiopulmonary bypass and in women on oral contraceptives. The AT III QUIPlate allows immunological studies to be completed in 24 hours.
