Gm typing by enzyme-linked immunosorbent assay (ELISA)
Zeitschrift Fur Rechtsmedizin. Journal of Legal Medicine
|January 1, 1984
Summary
A new solid-phase ELISA method allows for accurate Gm typing using anti-Gm antibodies. This technique offers a viable alternative to traditional methods, especially when specific reagents are scarce.
Area of Science:
- Immunology
- Serology
- Biochemistry
Background:
- Gm typing is crucial for various immunological and genetic studies.
- Conventional methods for Gm typing, like hemagglutination-inhibition, often rely on hard-to-obtain reagents such as human anti-Gm and anti-Rh0 sera.
Purpose of the Study:
- To develop and describe a solid-phase enzyme-linked immunosorbent assay (ELISA) for Gm typing.
- To provide an alternative method for Gm typing that overcomes limitations of conventional techniques.
Main Methods:
- A solid-phase ELISA was developed using microtiter wells coated with specific IgG or its fragments.
- A mixture of anti-Gm serum (or monoclonal anti-Gm antibody) and test serum was incubated in the coated wells.
- Peroxidase-labeled secondary antibodies were used to detect bound antibodies.
Main Results:
- The developed ELISA successfully identified Glm(3), G3m(16), and G3m(21) antigens.
- The method demonstrated potential as an alternative to conventional Gm typing techniques.
Conclusions:
- The solid-phase ELISA is an effective method for Gm typing.
- This ELISA system offers a practical alternative, particularly when conventional reagents are unavailable.
