Method for simultaneous quantitative analysis of several constituents in a sample
First Claim
1. A method for the simultaneous qualitative and quantitative analysis of a plurality of immunoreactive substances, especially of antigen-effective substances contained in a sample, comprising the steps of:
- A. placing the sample to be tested in a first carrier material which is free from antibodies;
B. providing a second carrier material, adjacent to said first carrier material, said second carrier material containing ingredients capable of undergoing immunoreactions with said substances in said sample, thereby forming precipitates;
C. causing the migration of said sample from said first carrier material into said second carrier material;
D. applying an electric field to the area of said first and second carriers for enhancing the migration of said sample from said first carrier material into said second carrier material substantially in the direction of said electric field;
the improvement comprising the steps of;
E. providing a plurality of second carrier materials, simultaneously adjacent to said first carrier material, andF. providing in each of said plurality of second carrier materials a different ingredient, each different ingredient being capable of undergoing a precipitate-forming immunoreaction with one of the substances to be analyzed in said sample.

Abstract
A method for simultaneous qualitative and quantitative analysis of antigensr antigen-effective substances in a sample provides placing the sample in a carrier medium through which it migrates toward a plurality of physically separate carrier strips. The medium on each strip contains a quantity of a specific ingredient, for example an antibody, which is expected to undergo a specific immunoreaction with one of the constituents in the sample, thereby producing a visible precipitate. The dimensions of the final precipitate then permit a direct measurement of the identified substance. A known concentration of a calibrating substance may be added to the sample to provide for calibration precipitates in the various strips. The apparatus for practicing the method includes a base plate on which the neutral, antibody-free carrier medium as well as the various strips containing media with antibodies or other immunoreactive ingredients are located. An electric field may be applied to aid in the migration of the sample in the medium.
