Laurell Rocket Electroimmunodiffusion & Radial Immunodiffusion

Discovery Diagnostics is the Canadian distributor for Helena Laboratories Laurell Rocket Electroimmunodiffusion and Radial Immunodiffusion products including;

Protein C Antigen Rocket PlatesProtein C Antigen Rocket Plates

Cat. No. Item
5357 Protein C Antigen Rocket Plates
  Protein C Rocket Plates, 5 x 12 wells/plate
  Rocket Antigen Report Form, 1 sheet
  Rocket Ruler, 1/pkg

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.




Protein S Antigen Rocket PlatesProtein S Antigen Rocket Plates

Cat. No. Item
5359 Protein S Antigen Rocket Plates
  Protein S Rocket Plates, 5 x 12 wells/plate
  Rocket Antigen Report Form, 1 sheet
  Rocket Ruler, 1/pkg


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).


Free Protein S ReagentFree Protein S Reagent

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 Platesvon Willebrand Factor Antigen (vWF:Ag) Rocket Plates

Cat. No. Item
5361 vWF:Ag Rocket Plates
  vWF:Ag Rocket Plates, 5 x 10 wells/plate
  Rocket Antigen Report Form, 1 sheet
  Rocket Ruler, 1/pkg

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.
