Concept
Blood plasma fractionation
Summary
Blood plasma fractionation are the general processes separating the various components of blood plasma, which in turn is a component of blood obtained through blood fractionation. Plasma-derived immunoglobulins are giving a new narrative to healthcare across a wide range of autoimmune inflammatory diseases. This widespread applicability is anticipated to leverage market prospects for plasma fractionation, pegged to witness a noteworthy 7% CAGR. COVID-19 pandemic is expected to generate growth opportunities for the plasma fractionation market.
Blood plasma is the liquid component of whole blood, and makes up approximately 55% of the total blood volume. It is composed primarily of water with small amounts of minerals, salts, ions, nutrients, and proteins in solution. In whole blood, red blood cells, leukocytes, and platelets are suspended within the plasma.
Plasma contains a large variety of proteins including albumin, immunoglobulins, and clotting proteins such as fibrinogen. Albumin constitutes about 60% of the total protein in plasma and is present at concentrations between 35 and 55 mg/mL. It is the main contributor to osmotic pressure of the blood and it functions as a carrier molecule for molecules with low water solubility such as lipid-soluble hormones, enzymes, fatty acids, metal ions, and pharmaceutical compounds. Albumin is structurally stable due to its seventeen disulfide bonds and unique in that it has the highest water solubility and the lowest isoelectric point (pI) of the plasma proteins. Due to the structural integrity of albumin it remains stable under conditions where most other proteins denature.
Many of the proteins in plasma have important therapeutic uses. Albumin is commonly used to replenish and maintain blood volume after traumatic injury, during surgery, and during plasma exchange. Since albumin is the most abundant protein in the plasma its use may be the most well known, but many other proteins, although present in low concentrations, can have important clinical uses.
