1. Flex Set detectors: each analyte is defined by both the specific capture bead and the complementary PE-conjugated detector antibody reagent. The corresponding bead and detector specificities, together with lyophilized standards are supplied for each analyte in a single package. Each antibody conjugate is supplied in buffered saline solution containing bovine serum albumin (BSA) and 0.09% sodium azide. For the list of available soluble protein analytes to construct multiplex assays, see Table 2.
2. PE-positive control detector: a single vial of PE-conjugated antibody, formulated for use at 50 pL/test. This reagent is used with the PE instrument setup bead F1 to set instrument compensation settings. Store at 4°C. Do not freeze.
