Commercial kits for 1,25-dihydroxyvitamin D compared with a liquid-chromatographic assay.

چکیده
Three commercially available kits for 1,25-dihydroxyvitamin D [1,25(OH)2D] determination were compared with a liquid-chromatographic method. Serum samples were analyzed for 1,25(OH)2D from 70 healthy subjects (age 2.2-17.5 years; 35 males, 35 females), some (n = 5) given orally high vitamin D3 doses. In addition, 1,25(OH)2D was measured in 28 patients with untreated diseases associated with low (n = 16) or high (n = 12) serum concentrations of the hormone. The results showed that the commercial kits were sufficiently accurate with respect to the comparison method and suitable for routine clinical work.

Analysis for 1,25-dihydroxyvitamin D in human plasma, after a liquid-chromatographic purification procedure, with a modified competitive protein-binding assay.
1,25-Dihydroxyvitamin D in plasma is measured by competitive protein-binding assay after isolation from plasma. The present method is improved, as compared with those hitherto described, with regard to receptor preparation, isolation of vitamin D metabolites from plasma, and procedure for the competitive protein binding. Receptor preparation from healthy rather than rachitic chicks, together wi...
متن کاملSimultaneous determination of 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, and 1,25-dihydroxyvitamin D in plasma or serum.
We describe a simultaneous assay for the principal vitamin D metabolites: 25-hydroxyvitamin D, 24-25-dihydroxyvitamin D, and 1,25-dihydroxyvitamin D. Special attention has been paid to simplification of the extensive extraction and purification procedures used in previously described simultaneous assays. All three metabolites were isolated with a single extraction step, followed by only one gra...
متن کاملProduction of 10-oxo-19-nor-25-hydroxyvitamin D3 by solubilized kidney mitochondria from chick and rat.
Cholate-solubilized chick kidney mitochondria that 1-hydroxylated 25-hydroxyvitamin-D3 (25-OH-D3) upon reconstitution also produced 10-oxo-19-nor-25-OH-D3, which co-eluted with 1,25-dihydroxyvitamin D3 (1,25-(OH)2-D3) on normal phase high performance liquid chromatography (HPLC) with hexane:propanol-2 (9:1), the traditional chromatographic system for isolating 1,25-(OH)2-D3. The 10-oxo derivati...
متن کامل[The effect of purification procedures on the determination of serum level of 1,25-dihydroxyvitamin D].
The advance in knowledge of clinical disorders involving calcium and bone diseases has resulted in part from the development of assay procedures for the major vitamin D metabolites, but the values of the same samples measured in different laboratories vary considerably. They suggest that the chromatographic purification involved in these assays seems to be a critical step. In this study, we com...
متن کاملEvidence for a monoglucuronide of 1,25-dihydroxyvitamin D3 in rat bile.
We have isolated and characterized a monoglucuronide fraction of 9,10-secocholesta-5,7,10(19)triene-1 alpha, 3 beta, 25-triol, 5,6-cis isomer (1,25-dihydroxyvitamin D3) from rat bile. Polar radioactive metabolites of 1,25-dihydroxyvitamin D3 were purified by a sequence of chromatographic procedures which utilized Amberlite XAD-2, diethylaminohydroxypropyl Sephadex LH-20, liquid-liquid partition...
