Simple method for preparing the cellular intermediate EAC14, and its use for estimation of the second component of
Clinical Chemistry
|April 1, 1986
Summary
Researchers developed a method using sheep erythrocytes sensitized with complement components C1 and C4 (EAC14) to measure the second component of complement (C2) in human serum.
Area of Science:
- Immunology
- Complement system research
Background:
- The complement system is crucial for innate immunity.
- Accurate quantification of complement components is essential for diagnosing immune deficiencies.
Purpose of the Study:
- To establish a reliable method for quantifying the second component of complement (C2) in human serum.
- To validate the use of EAC14 cells for C2 estimation.
Main Methods:
- Preparation of EAC14 cells by incubating sensitized sheep erythrocytes with normal serum.
- Utilizing EAC14 cells in a buffer containing calcium ions (Ca2+) but free of magnesium ions (Mg2+).
Main Results:
- Successfully prepared EAC14 cells suitable for C2 quantification.
- Demonstrated the utility of the prepared EAC14 cells for estimating C2 levels in human serum.
Conclusions:
- The described method provides a viable approach for C2 measurement.
- EAC14 cells are effective reagents for assessing complement component C2 activity.
