Capillary Electrophoresis Buffer with Cationic Polymer for Rapid Albumin Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional capillary electrophoresis methods require about 10 minutes to separate albumin and γ-globulin, which is inefficient for large-scale clinical specimen analysis, necessitating multiple capillaries to shorten separation time.
Innovation Solution
A sample analysis method using an alkaline solution with a cationic polymer for capillary electrophoresis, which increases the charge difference between albumin and γ-globulin, allowing for their efficient separation in a shorter time by applying a voltage across a capillary flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional capillary electrophoresis methods are used to separate albumin and γ-globulin, then separation can be achieved, but the separation time is about 10 minutes which is too long for large-scale clinical specimen analysis
Solution Approach 1:
The patent changes the chemical parameters of the electrophoresis buffer by adding a cationic polymer to create a charged environment that enhances the charge difference between albumin and γ-globulin. This parameter change in the buffer composition enables faster electrophoretic separation, reducing separation time from 10 minutes to under 200 seconds while improving analysis efficiency for clinical specimens
2Productivity
If multiple capillaries are prepared to shorten separation time, then analysis capacity increases, but system complexity and preparation requirements increase
Solution Approach 1:
Instead of increasing the number of capillaries (hardware expansion), the patent changes the chemical parameters of the electrophoresis buffer by incorporating a cationic polymer. This modifies the charge characteristics of the buffer system to enhance separation speed, allowing single-capillary systems to achieve high processing capacity without increased system complexity or preparation requirements
