Abstract

Abstract A method for determining boundary points on electrophoretic patterns whereby boundary points can be easily and accurately added onto or erased from fractionated patterns or analogue patterns by utilizing a densitometer for obtaining fractionated patterns of serums formed by an electrophoresis, a computer for making necessary operations and data treatments, an input terminal device for putting boundary point position informations or the like into the computer and an output terminal device which can record and digitally type analogue patterns with the output of the computer and means for working the method. Any input error by the input terminal device can be corrected.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 147 words
A method for determining boundary points on electrophoretic patterns, comprising a step wherein a densitogram is obtained from fractionated patterns formed by an electrophoresis, a step wherein the data obtained by sampling from said densitogram and the boundary point information determined on the basis of said data are memorized in a computer, and a step wherein the boundary point erasing or new boundary point setting information is put into said computer by a terminal device on the basis of an analogue pattern obtained from said fractionated patterns to alter the boundary point information memorized in said computer, a boundary point being put into said computer on the basis of an input distance information when the boundary point is to be added, and the boundary point being erased by putting the address number of the boundary point into said computer when the boundary point is to be erased.
Claim 2
Independent Claim 147 words
A method for determining boundary points on electrophoretic patterns, comprising a step wherein a densitogram is obtained from fractionated patterns formed by an electrophoresis, a step wherein the data obtained by sampling from said densitogram and the boundary point information determined on the basis of said data are memorized in a computer, and a step wherein the boundary point erasing or new boundary point setting information is put into said computer by a terminal device on the basis of an analogue pattern obtained from said fractionated patterns to alter the boundary point information memorized in said computer, a boundary point being put into said computer on the basis of an input distance information when the boundary point is to be added, and the boundary point being erased by putting the address number of the boundary point into said computer when the boundary point is to be erased.
Claim 3
Dependent Claim 28 words
A method according to claim 1, further comprising a step wherein an analogue pattern is recorded and digitally typed on the basis of the output of said computer.
