H. Shinohara et al., THE USE OF POLY R-478 AS A MARKER TO DETERMINE GASTRIC-EMPTYING AND INTESTINAL PROPULSIVE MOTILITY IN SUCKLING RATS, Physiological Research, 44(5), 1995, pp. 281-286
During our studies on gastrointestinal motility in suckling rats using
Cr-51 or Cr-51-EDTA as markers, we noticed that these markers - in co
ntrast to studies in adult rats - ''adhered'' to the gastrointestinal
wall of sucklings. We therefore decided to test the use of another non
-absorbable marker Poly R-478 (an acetylated anthrapyridone chromophor
e linked to an polyamino-ethylene-sodium ethylene sulfonate copolymer
backbone developed by the Dynapol Corporation (Pale Alto, CA). This ne
w method has appeared to be useful.
