ABSTRACT
The effects of tritiated amino-acids, arginine, lysine, histidine and aspartic acid on the growth and development of two-cell mouse embryos, cultured in vitro, were investigated. The LD50 for the dibasic amino acids, measured on the third day of growth, ranged from 30 to 130 nCi/ml. This was compared with the DNA precursor, thymidine, for which the LD50 was 80 nCi/ml.
