Recombinant barnase as a label in ELISA

Abstract

Recombinant barnase was proposed as a label in the enzyme-linked immunosorbent assay (ELISA). Barnase-conjugated pig transferrin was prepared by the periodate oxidation procedure. Solid-phase bound barnase activity was determined from the change in RNA-ethidium bromide complex fluorescence upon RNA hydrolysis. The sensitivity of transferrin-barnase conjugate determination in ELISA was no less than 5 ng per well. The conjugate was applied in competition ELISA for free transferrin determination.
