图三.缓冲盐水（0 0 *）、血浆（0 0）或尿液（X X）中的非放射性戊巴比妥对β '4C]戊巴比妥与兔抗血清结合的抑制作用。孵育液含正常兔血清0.10ml、兔抗血清0.10nml（0.4 mg蛋白质）、0.01 ml [1，4C]戊巴比妥（0.1 nmole）和0.01 ml标准未标记戊巴比妥（1 - 100 ng）或未知样品和足量磷酸盐缓冲盐水（0.01 M磷酸盐，pH 7.4），使最终体积为0.50 ml。用最小二乘法计算回归线。
Fig. 3. Inhibition of binding of ['4C]pentobarbital to rabbit antiserum by nonradioactive pentobarbital in buffered saline (0 0 *), plasma (0 O), or urine (X X). Incubation medium consisted of 0.10 ml of normal rabbit serum, 0.10 nml of rabbit antiserum (0.4 mg of protein), 0.01 ml of ['4C]pentobarbital (O.1 nmole), and 0.01 ml of either standard unlabeled pentobarbital (1 to 100 ng) or unknown sample and sufficient phosphatebuffered saline (O.O1M phosphate, pH 7.4) to make a final volume of 0.50 ml. Lines of regression were calculated by the method of least squares.
