A computer program for the evaluation of ELISA data obtained using an automated microtiter plate absorbance reader

Area of Science:

• Immunology
• Bioinformatics
• Computational Biology

Background:

• Enzyme-Linked Immunosorbent Assay (ELISA) is a common immunological assay.
• Manual analysis of ELISA data can be time-consuming and prone to error.
• Accurate quantification of antibody titers and concentrations is crucial for research and diagnostics.

Purpose of the Study:

• To introduce a novel computer program for automated ELISA data processing.
• To enhance the efficiency and accuracy of calculating antibody titers and concentrations.
• To demonstrate the program's utility in quantifying specific antibody levels.

Main Methods:

• Development of a microcomputer program to process optical density readings from 96-well microtiter plates.
• Automated data arrangement in an 8x12 format mirroring the microtiter plate layout.
• Implementation of algorithms for calculating sample titers and comparing them to a standard for concentration determination.

Main Results:

• The program successfully calculates titers and antibody concentrations from raw ELISA data.
• Automated comparison with standards provides accurate quantification of antibody levels.
• Demonstrated application in measuring murine antibodies against Streptococcus pneumoniae cell wall polysaccharide (PnC).

Conclusions:

• The developed computer program offers an efficient and accurate method for ELISA data analysis.
• Automation of titer calculation and concentration determination streamlines laboratory workflows.
• This tool facilitates reliable quantification of specific antibodies in immunological studies.
