Dialysis of human plasma removes citrate, generating thrombin and fibrinogen derivatives. These derivatives form stable adducts with elastin, influenced by calcium, thrombin, and time.

Area of Science:

Biochemistry
Hematology

Background:

Human plasma contains citrate, calcium, and fibrinogen.
Thrombin plays a key role in coagulation.
Elastin is a major protein in connective tissues.

Purpose of the Study:

To investigate the formation of stable complexes between plasma components and elastin.
To understand the role of calcium and thrombin in this process.

Main Methods:

Dialysis of human citrated plasma against a phosphate buffer with calcium.
Analysis of soluble fibrinogen derivatives formation.
Assessment of adduct formation between derivatives and elastin.

Main Results:

Citrate removal during dialysis induced thrombin generation.

Soluble fibrinogen derivatives (fibrin monomers/polymers) were formed.

These derivatives formed stable adducts with human and bovine elastin.

Adduct formation was dependent on time, calcium, and thrombin concentrations.

Conclusions:

A stable adduct can form between soluble fibrinogen derivatives and elastin.
Calcium and thrombin are critical for this adduct formation process.
