A sensitive and specific reversed-phase liquid-chromatography (HPLC) method for the determination of urinary free and conjugated 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG) was developed. Sample preparation is minimal and the method is ideally suited for routine clinical assays of this catecholamine metabolite. Reported in this paper are excretion(More)
A rapid and sensitive high-performance liquid-chromatographic assay for tryptophanase based upon the fluorometric measurement of the enzymatically liberated indole was developed. The total incubation time is 20 min, and the reversed-phase separation is fast (elution time of indole in 8 min) and reproducible. The sensitivity of the method is in the nanomole(More)
Human leukocyte dialysates contain components capable of amplifying cutaneous delayed-type hypersensitivity (DTH) reactions. In the present study, two such amplifiers, both less than 3500 m.w., were partially purified from human leukocyte dialysates by gel filtration on Sephadex G-10 followed by high pressure reverse-phase liquid chromatography. These(More)
A crude in vitro transcription system which selectively transcribes DNA fragments containing the promoter region of the Tetrahymena pyriformis rRNA gene has been prepared from T. pyriformis. The system requires both an S100 fraction of lysed isolated macronuclei and an S100 extract of whole cells. When a HhaI-HindIII fragment of the promoter containing(More)
