THE DEVELOPMENT OF A RADIOIMMUNOASSAY FOR OXYTOCIN: RADIO-IODINATION, ANTIBODY PRODUCTION AND SEPARATION TECHNIQUES

CHARD, T., KITAU, M. J., LANDON, J.·1970·Journal of Endocrinology

Abstract

SUMMARY: A simple and rapid method is described for labelling oxytocin with 131I at a high specific activity. This method is compared with those of previous workers. A satisfactory antiserum has been raised by direct intra-lymph node injection of oxytocin adsorbed to carbon microparticles. A number of methods for separating antibody-bound from free oxytocin are described, and reasons given for preferring a procedure using ammonium sulphate precipitation. These data form the basis for developing a radioimmunoassay intended for the determination of oxytocin in human plasma.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • The human posterior pituitary contains approximately 21 μg of oxytocin, whereas that of the rat contains 0.5-1 μg.

    “the human posterior pituitary contains approximately 21 μg of oxytocin 72, 73, 74, whereas that of the rat contains 0.5–1 μg.”
  • By the 1980s, many laboratories had generated radioimmunoassays for oxytocin using independently produced antibodies, and most but not all required extraction.

    “By the 1980s, many laboratories had generated radioimmunoassays for oxytocin, using independently produced antibodies 58, 72, 73, 74, 94, 95, 96, 97, 98] and most, but not all 99, 100, required extraction.”

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.
