BIOASSAY OF OXYTOCIN BY CHANGES IN LIGHT PENETRATION THROUGH RAT MAMMARY GLAND TISSUE IN VITRO
Keyword(s):
SUMMARY A method for the bioassay of oxytocin in the lactating rat mammary gland in vitro is described. The changes in transparency induced by oxytocin in a flat segment of the gland are recorded by means of a CdS photoresistor and a simple Wheatstone bridge. The sensitivity of the assay in routine use is about 0·5–10 μu. oxytocin, the index of precision being about 0·1.
