Study Notes
Plasma Composition
- Plasma is the non-cellular portion of blood.
- Total plasma protein level ranges from 6-7 gm/dl.
Types of Plasma Proteins
- There are two main categories of plasma proteins: albumin and globulin.
Albumin
- Albumin is not precipitated by half-saturated ammonium sulfate.
- Albumin constitutes over half of the total protein.
- Albumin level ranges from 3.5-5.5 gm/dl.
- Albumin is a simple protein and a single entity.
Globulin
- Globulin is precipitated by half-saturated ammonium sulfate.
- Globulin level ranges from 2-3 gm/dl.
- Globulin is a complex protein with many components.
- Subglobulins (α1, α2, β, and γ-globulins) are detected as bands on electrophoresis.
Age-Related Changes
- After the age of 40, albumin levels gradually decline, and globulin levels increase.
Electrophoresis
- Electrophoresis is used to separate and identify plasma proteins.
- The electrophoretic pattern is shown in Fig. 1a.
- Different plasma protein bands are semi-quantitated using a densitometer (Fig. 1b).
