Fluorescence linked immunosorbant assays using microtiter plates

Area of Science:

• Biochemistry
• Immunology
• Analytical Chemistry

Background:

• Fluorescence methods are common for detecting binding events.
• Enzyme-linked immunosorbent assays (ELISA) are predominant for microtiter plate screening.
• There is a need for alternative, effective plate-based detection methods.

Purpose of the Study:

• To explore parameters for effective fluorescence-based detection in microtiter plates.
• To establish fluorescent immunosorbant assays (FLISA) as a viable alternative to ELISA.
• To optimize FLISA for screening applications, including phage antibody selection.

Main Methods:

• Investigated various microtiter plates suitable for fluorescence detection.
• Evaluated different immobilization strategies for antibodies and binding targets.
• Assessed the performance of diverse fluorescent dyes and fluorescent proteins.

Main Results:

• Identified optimal microtiter plates and immobilization techniques for FLISA.
• Demonstrated that FLISA can achieve comparable sensitivity and reliability to ELISA.
• Successfully applied FLISA in screening phage antibody selections.

Conclusions:

• Fluorescent immunosorbant assays (FLISA) are a robust and effective method for plate-based screening.
• FLISA provides a valuable alternative to ELISA, particularly for antibody detection and selection.
• Optimization of parameters ensures FLISA's utility in various immunological assays.
