The section contains information about the leading segments in the industry. Based on product, the recombinant Protein A resin devices segment is expected to account for 74.4% of the global share in 2025.
| By Product | Value Share (2025) |
|---|---|
| Recombinant Protein A Resin | 74.4% |
The Recombinant Protein A Resin segment is projected to be a dominating segment in terms of revenue, accounting for almost 74.4% of the market share in 2025.
The reason behind Recombinant Protein A resin segment being the dominating segment is that recombinant protein A is genetically engineered with optimum IgG-binding domains that leads to a good capacity for the antibody and hence, easier purification from a complex sample as well. Also, Recombinant protein A resins often have a hard time against a high salt concentration and denaturants. These resins could be used under very stringent conditions.
Commercially available recombinant protein A resins are engineered for large-scale purification. Therefore, it allows for industrial production of antibodies. Recombinant protein A can bind to a wide range of antibody subclasses from different species, thus proving versatile for a variety of needs in the purification of antibodies. This property makes the protein A resin interact selectively with the Fc region of antibodies and, therefore, minimize contamination with other proteins. The wide usage recombinant protein A reaffirms their strategic position within the market.
| By Application | Value Share (2025) |
|---|---|
| Antibody purification | 74.9% |
Antibody purification segment will be the one with the dominating revenue sharing nearly 74.9% of the total market share by 2025.
One of the most widely used techniques for separating and purifying antibodies from a mixture is antibody purification using Protein A resins. It is primarily due to the high affinity that Protein A, a protein from Staphylococcus aureus, has for binding to the Fc region of IgG antibodies. This allows for selective capture and separation Because this technique is so effective and specific it is usually used in the production of research and therapeutic antibodies.
Through antibody purification a purification procedure is achieved to raise the purity of antibodies for use in research, diagnosis and treatment. In research applications such as immunohistochemistry, cellular imaging and western-blotting antibodies are employed as probes to identify particular antigen. Affinity purification methods use antibodies to attach to chromatography media.
The therapeutic qualities and functions of each subclass may vary. The two heavy and two light chains that comprise an antibody can be separated through purification.
This makes it possible to examine each chain's unique property
