General description

Cohn fraction IV consists of α and β-globulins. It is a plasma by-product produced during γ-globulin synthesis.

Application

Globulins Cohn fraction IV-4 human has been used in differential scanning calorimetry (DSC) to test the effect of low-dose ionizing radiation. It has also been used in the preparation of plasma protein solution for biophysical studies.
Globulins may in binding of 5-methoxypsoralen to blood fractions. It may used as positive control for Granulocyte immunofluorescence test (GIFT). It may also used to study the thermal denaturation of mixtures of human serum proteins.

Biochem/physiol Actions

The Cohn fraction IV (α-globin enriched) mediates the inhibition of brain neurotransmitter receptors.

Other Notes

Predominantly α- and β-globulins
