Immunoassay for human serum hemojuvelin.
BACKGROUND Hemojuvelin, a critical regulator of iron homeostasis, is involved in the regulation of hepcidin expression and iron homeostasis. It is expressed both as a membrane-bound form and as a soluble one. Serum hemojuvelin can be produced by secretion following furin cleavage or by proteolytic cleavage of the membrane-bound form by matriptase 2 (TMPRSS6). These forms contribute to down-regu...
متن کاملImmunoassay for human serum hepcidin.
We developed and validated the first serum enzyme-linked immunosorbent assay for hepcidin, the principal iron-regulatory hormone that has been very difficult to measure. In healthy volunteers, the 5% to 95% range of hepcidin concentrations was 29 to 254 ng/mL in men (n = 65) and 17 to 286 ng/mL in women (n = 49), with median concentrations 112 versus 65 (P < .001). The lower limit of detection ...

متن کاملDirect immunoassay of triiodothyronine in human serum.
A sensitive and precise radioimmunoassay for the direct measurement of triiodothyronine (T(3)) in human serum has been designed using sodium salicylate to block T(3)-TBG binding. This assay is sufficiently sensitive to quantitate T(3) accurately in 50-100 mul of normal serum and to measure quantities as small as 12.5 pg in 0.2 ml of hypothyroid serum. The T(3) values observed in euthyroid subje...
متن کاملSubstrate-labeled fluorescent immunoassay for phenytoin in human serum.
A homogeneous substrate-labeled fluorescent immunoassay has been applied to the measurement of phenytoin concentrations in human serum. We coupled a fluorogenic enzyme substrate, galactosyl-umbelliferone, covalently to a derivative of phenytoin. Under assay conditions, this drug-substrate conjugate was nonfluorescent but became fluorescent upon hydrolysis catalyzed by bacterial beta-galactosida...
