Fully automatic instrument system for biochemical assays

An instrument for performing a multiplexed immunoassay on a biological sample, comprising:

• A) a controller;
• B) a controlled robotic gantry;
• C) a sample plate comprising the biological sample;
• D) a reagent kit comprising a paired-binding moiety comprising:
• a) a first moiety of the paired-binding moiety comprising i) a first antibody or a first antibody fragment that is pre-selected to bind an analyte;
• ii) a first nucleic acid target label comprising a first identity that is analyte-specific to the analyte;
• iii) a first nucleic acid tag;
• b) a second moiety of the paired-binding moiety comprising i) a second antibody or a second antibody fragment that is pre-selected to bind the analyte;
• ii) a second nucleic acid target label comprising a second identity that is analyte-specific to the analyte;
• iii) a second nucleic acid tag;
• wherein the first nucleic acid tag of the first moiety of the paired-binding moieties is pre-selected to bind to a first magnetic bead substrate, and the second nucleic acid tag of the second moiety of the paired binding moieties is pre-selected to bind a second magnetic bead substrate;
• E) a magnetic bead processor capable of holding and releasing the first magnetic bead substrate and the second bead substrate;
• and
• F) a controlled washer configured to wash the first magnetic bead substrate and the second magnetic bead substrate.
