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 (?-globin enriched) mediates the inhibition of brain neurotransmitter receptors.
General description
Cohn fraction IV consists of ? and ?-globulins. It is a plasma by-product produced during ?-globulin synthesis.
