Used to measure Immunoglobulin A (IgA) levels in biological samples from monkeys, such as serum, plasma, or mucosal secretions. This kit is essential in immunological research involving non-human primates, particularly in studies related to mucosal immunity, infectious diseases, vaccine development, and gut health. It enables researchers to quantify IgA responses accurately, helping assess immune activation or suppression in experimental models. Commonly used in pharmaceutical testing, virology, and preclinical studies where monkey models are employed to mimic human immune responses.
