Immunoassay of plasma vasopressin in man

Abstract

A radioimmunoassay for arginine vasopressin has been developed that is sensitive to the hormone at 1 pg/ml. When plasma was filtered on G-25 Sephadex, immunoreactivity was detected in three regions. Endogenous arginine vasopressin was the third and smallest of the peaks and was recovered just after the salt. By combining gel filtration with immunoassay, we have made precise measurements of arginine vasopressin in a few milliliters of plasma.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Born et al. achieved plasma vasopressin of 20 pg/ml after 40 IU intranasal, higher than Robertson et al. reported for any patient, including those with pathologically elevated vasopressin; maximal urine concentrating ability in humans occurs at about 5 pg/ml.

    “Born et al. achieved plasma concentrations of 20pg/ml after giving 40IU vasopressin (17).These are higher than Robertson et al. reported for any patient, including those with pathologically elevated vasopressin secretion; in man, maximal urine concentrating ability is achieved at a vasopressin concentration of ~5pg/ml (33).”

    From Intranasal Oxytocin: Myths and Delusions (2016) · cites this paper as [33]

  • Robertson et al. found that two vasopressin radioimmunoassays on unextracted plasma yielded values at least two orders of magnitude higher than those inferred from other evidence, and these values did not fluctuate in parallel with endogenous authentic vasopressin.

    “Robertson et al. showed that two radioimmunoassays for vasopressin yielded measurements in unextracted plasma that were at least two orders of magnitude greater than those inferred from other evidence, and which did not fluctuate in parallel with endogenous authentic vasopressin (33,58).”

    From Intranasal Oxytocin: Myths and Delusions (2016) · cites this paper as [33]

  • High molecular weight factors in raw plasma interfere with the binding of antibodies to oxytocin and vasopressin, leading to high and erroneous readings.

    “high molecular weight factors in raw plasma interfered with the binding of antibodies to the hormones, leading to high and erroneous readings”
  • Like the first radioimmunoassays of unextracted plasma, using an enzyme-linked immunoassay to measure plasma levels without extracting samples generates impossibly high and wholly erroneous measurements.

    “Like the first radioimmunassays of unextracted plasma, this generates impossibly high and wholly erroneous measurements.”
  • Robertson et al. resolved three peaks of immunoreactivity by filtering plasma on G-25 Sephadex; only the third and smallest was consistent with true vasopressin, being recovered in the same location as pure vasopressin.

    “By filtering plasma samples on G‐25 Sephadex, they resolved three peaks of ‘immunoreactivity’, only the third and smallest of which was consistent with true vasopressin, being recovered in the same location as pure vasopressin 78.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
