Abstract

Peptides with transmitter-like characteristics are being found in many brain areas. The application of immunocytochemical and radioimmunoassay methods has contributed much to the clarification of these neuronal systems. Here we report the development of a rat monoclonal antibody produced by a hybrid myeloma and its application to the study of one of these peptides, substance P. The hybrid clone, isolated after fusion of mouse myeloma cells with hyperimmune rat spleen cells, allowed us to obtain a standardized and permanent source of monoclonal substance P antibodies in a culture cell system. This antibody recognizes the COOH-terminal part of substance P in radioimmunoassay down to 10-20 fmol. It does not crossreact with other known mammalian brain peptides tested. By immunofluorescence the antibody was shown to bind specifically and with a remarkably low background to nerve terminals and cell bodies located in clearly defined nuclear organizations of the central nervous system.

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.
