|August 1, 1975

Summary

Researchers successfully determined the Gm(1) factor in human cadaver endolymph and blood. This finding indicates reliable Gm(1) factor analysis is possible in both sample types.

Area of Science:

Forensic Anthropology
Immunogenetics
Human Anatomy

Background:

The Gm(1) factor is a genetic marker found in human serum proteins.
Determining the Gm(1) factor is crucial for various forensic and anthropological studies.
Previous research has focused on blood samples, with limited investigation in other biological fluids.

Purpose of the Study:

To investigate the feasibility of determining the Gm(1) factor in endolymph from human cadavers.
To compare the results of Gm(1) factor determination in endolymph with those from blood samples.
To assess the reliability and potential challenges in analyzing post-mortem samples.

Main Methods:

Human cadavers were used as the source of biological samples.
Endolymph was carefully collected from the inner ear.
Blood samples were also collected for comparative analysis.
Standard immunogenetic techniques were employed for Gm(1) factor determination in both sample types.

Main Results:

The Gm(1) factor was successfully determined in endolymph samples.
No significant difficulties or anomalies were encountered during endolymph analysis.
Results from endolymph samples were comparable to those obtained from blood samples.
The Gm(1) factor determination in post-mortem blood samples also yielded reliable results.

Conclusions:

The Gm(1) factor can be reliably determined in endolymph from human cadavers.
Endolymph serves as a viable alternative or supplementary source for Gm(1) factor analysis.
This study validates the use of endolymph in post-mortem genetic investigations.
The findings support the expansion of Gm(1) factor analysis to include endolymph in forensic casework.
