Antigens are commonly referred to as substances that are capable of triggering an immune response in a host by activating the lymphocytes or initiating antibody production against infections. Depending upon the fact that they either enter the human body or originate within the body, viral antigens are classified as foreign or self-antigens respectively. Among these, self-antigens comprise mutated or overexpressed proteins. However, foreign antigens are likely to include bacteria, parasites, viruses, chemicals and sometimes toxins & proteins found in food products.
Viral antigens, defined as an antigen that contains multiple antigenicity that is protein in nature. These multiple antigenicity present on viral antigens are strain-specific and closely related to the virus particle. Viral antigens are basically protein encoded and specified by the viral genome that can be detected by an explicit immunological response. These highly immunogenic antigenic determinants elicit strong immune responses, owing to which they are used to diagnose various viral infections for clinical research purposes.
Viral antigens in the viral antigens market are majorly found in distinct formats such as purified, inactivated pathogens, cell lysates and antigen carrier conjugates. A wide range of native state viral antigens is highly in demand, particularly for vaccine research and in-vitro diagnostics. Standard properties recommended for apt viral antigens include higher specificity & sensitivity, simple production & quality control, capability of a viral protein to mimic its way into the cells and level of safety in cases of oncogenic viruses. Under the product type segment defined for the viral antigens market, the influenza viral antigens accounts for a significant revenue share in the global viral antigens market followed by the adenovirus viral antigens. Herpes Simplex Virus (HSV) antigen and rotavirus antigen are commonly recommended viral antigens in the viral antigens market to fight various acute diseases such as AIDS, influenza and others. These viral antigens find applications in various diagnostic techniques, which include ELISA, immunodiagnostic assays, and hemagglutination tests, in the viral antigens market. The major potential end users for the viral antigens market, where these antigens are highly in demand and generate significant revenues, include hospitals, associated diagnostic laboratories, diagnostic laboratories & centres and academic & research institutes.
Viral Antigens Market: Drivers and Restraints
The growing demand for recombinant viral antigens that are capable of producing recombinant viral proteins, thereby ensuring that the ELISAs are safe, specific and rapid, is expected to be among major factors driving the viral antigens market over the forecast period. Moreover, the high capability of viral antigens to reduce the risk of false negatives, growing incidence of acute diseases such as hepatitis, AIDS, cancers & infectious diseases, and increase in diagnostic population for variant diseases is also expected to drive the revenue growth of the global viral antigens market. Approval and launch of new viral antigens is another important factor contributing to the growth of the global viral antigens market. However, increase in the risk of viral infection and safety issues are restraining the revenue growth of the global viral antigens market.

Viral Antigens Market: Overview
The global viral antigens market is expected to register modest growth over the forecast period due to increase in the incidence of acute life-threatening diseases such as influenza, hepatitis and AIDS, which are among major threats for global public health. A number of viral antigens intended for antibody detection or to be used as a positive control to perform a variety of immunodiagnostic assays such as ELISA are being introduced in the viral antigens market. They are being offered by leading players such as Jena Bioscience GmbH, Biologics International Inc. and Creative Diagnostics. Due to the presence of domestic manufacturers, there is strong competition among domestic and regional players in the viral antigens market. Among the different types of viral antigens indicated for various diagnostic applications, the adenovirus antigen segment is expected to contribute a significant revenue share in the global viral antigens market over the forecast period followed by the influenza antigen product segment. Among the pathogen type segment, inactivated viral pathogen is expected to register substantial demand from diagnostic centres and hospitals as compared to purified pathogens. Diagnostic laboratories and centres, followed by hospital-associated diagnostic laboratories, are expected to contribute a high revenue share in the global viral antigens market as these are the most significant platforms to perform immunodiagnostic tests.
Viral Antigens Market: Regional Outlook
Geographically, the global viral antigens market is segmented into North America, Latin America, Europe, Asia-Pacific excluding Japan (APEJ), Japan and the Middle East & Africa (MEA). North America is expected to generate the highest revenue in the global viral antigens market owing to the growing prevalence of acute diseases such as HIV AIDS and influenza, thus elevating research applications of viral antigens in the region as compared to other regions. The viral antigens market in Asia Pacific excluding Japan is expected to grow at a significant CAGR due to the large presence of domestic players that manufacture viral antigens to perform immunoassays and hemagglutination tests on the affected population to diagnose viral infection. Europe is expected to register the second-largest share in the global viral antigens market throughout the forecast period owing to an increase in the presence of viral antigens distributors and suppliers across the region.
Viral Antigens Market: Key Players
The global viral antigens market is highly fragmented owing to the presence of a large number of domestic manufacturers. Some of the key players operating in the global viral antigens market are Bio Rad Laboratories, Inc.; Creative Diagnostics; Viral Antigens, Inc.; The Native Antigen Company Ltd.; Jena Bioscience GmbH; GenScript Corporation; Aalto Bio Reagents and Advanced Biotechnologies Inc.
