Product type
Vaccine antigen proteins are essential components used in the development of vaccines. They are typically derived from pathogens such as viruses or bacteria and are designed to elicit an immune response in the body. These proteins can be produced through various methods, including recombinant DNA technology, which allows for the generation of specific antigens that mimic those found in the actual pathogen.
| Source | Recombinant proteins or inactivated pathogens |
| Purity | Typically greater than 95% |
| Form | Lyophilized powder or liquid solution |
| Storage conditions | 2°C to 8°C or as specified |
| Shelf life | Typically 12 to 24 months |
When selecting vaccine antigen proteins, buyers should consider the specific pathogen and the type of immune response desired. It's important to specify the source of the antigen, such as whether it is recombinant or inactivated, as well as the required purity levels. Certifications, such as compliance with Good Manufacturing Practices (GMP), may also be relevant. Additionally, buyers should indicate the quantity needed, as larger volumes may be subject to different pricing structures.
