Improved radioimmunoassay technique for measuring serum thymopoietin.
An improved radioimmunoassay technique for measuring serum thymopoietin has been developed which obviates the spurious displacements previously obtained with serum samples, and increases sensitivity to 20 pg. Key improvements involved further purification of labeled thymopoietin, sequential incubations to enhance sensitivity and the use of charcoal-treated serum blanks to render controls and unknown samples comparable to the standard curve.
