Abstract
Abstract This invention is a template structure for electrophoresis and immunoelectrophoresis processes including a relatively thin sheet member inert to and adapted to receive a stabilizing media gel on one side and having an aperture therein. More particularly, this invention relates to a thin sheet member with an aperture and adapted to receive on a surface a relatively thin coating of the stabilizing media gel forming a well with the aperture to receive a sample of serum therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A PROCESS FOR ELECTROPHORESIS AND IMMUNOELECTROPHORESIS COMPRISING: A. COATING ONE SIDE OF A SHEET MEMBER HAVING AT LEAST ONE APERTURE THERETHROUGH WITH A STABILIZING MEDIA GEL, B. ALLOWING SAID STABILIZING MEDIA TO HARDEN WHEREIN SAID APERTURE IN COMBINATION WITH SAID HARDENED STABILIZING MEDIA GEL FORM AT LEAST ONE WELL, C. DEPOSITING A SAMPLE TO BE TESTED WITHIN SAID WELL, D. INOCULATING SAID SAMPLE TO BE TESTED, E. TREATING ELECTROPHORETICALLY SAID STABILIZING MEDIA COATED SHEET MEMBER, F. STAINING SAID ELECTROPHORETICALLY TREATED SHEET MEMBER OF STEP (E) TO ANALYZE SAID SAMPLE, AND G. SCANNING SAID STAINED ELECTROPHORETICALLY TREATED SHEET MEMBER OF STEP (F) FOR RESULTS.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
35 words
The process of claim 2 additionally including prior to step (a) superimposing said sheet member with a mold member having at least one extending portion passing through said at least one aperture said extending thereabove.
Claim 5
Dependent Claim
34 words
The process of claim 2 wherein said sheet member is inert to said stabilizing media gel, and said stabilizing media gel is allowed to harden from between about 5 minutes to about 10 minutes.
Claim 6
Dependent Claim
23 words
