Human Immune Function
Evaluation Tools
The immune system is a key protection system against hazardous foreign substances. Proper functioning of the
immune system can be monitored by evaluating the antibody response to foreign antigens. However, immune
function is affected by a variety of exogenous environmental agents (e.g. infectious bacteria and virus), drugs (e.g.
immunosuppressants and immunomodulators), and intrinsic factors (e.g. stress, GI disorders and aging associated with
immuno-senescence). The consequence of lowered immune function may increase health risks such as susceptibility
to diseases causative pathogens.
To measure immune function, Chondrex provides antibody ELISA kits to determine IgA and IgG antibody levels to
various types of pathogenic and non-pathogenic environmental factors (Table 1). This series of ELISA kits employ the
ChonBlock® buffer system (ref paper), which eliminates non-specific reactions, as well as ionic interactions in indirect
ELISAs to provide accurate assay results. Chondrex also provides ChonBlock® buffer for in-house use for individual
assay purposes (Table 2). Please contact us for more information at [email protected].
