Patent ID: 8128941

Claim:
A method for detecting antibodies to one or more mycobacterial antigens in a sample from a non-human primate, comprising: obtaining the sample from the non-human primate; contacting the sample with a first composition comprising an antigen-particle conjugate comprising multiple mycobacterial antigens conjugated to a particle, wherein contacting the sample with the first composition permits the binding of antibodies to one or more of the mycobacterial antigens and formation of an antibody-antigen-particle complex; contacting the sample with a second composition comprising multiple mycobacterial antigens immobilized at one or more locations on a solid support, permitting binding of the antibody-antigen-particle to one or more immobilized antigens of the second composition; and detecting the formation of the bound antibody-antigen-particle complex; wherein each antigen present in the first composition is present in the second composition.
