Abstract
- Endogenous LH, FSH, TSH, growth hormone, prolactin and insulin were measured by radioimmunoassay in human plasma samples stored at 4 degrees, 20 degrees and 37 degrees for up to 8 days or repeatedly frozen and thawed. 2. At 4 degrees, the concentrations of all hormones were stable for at least 8 days; at 20 degrees only LH, FSH and TSH were stable for 8 days; at 37 degrees only TSH was stable for 8 days. 3. All the hormones except insulin were stable during 5 freeze-thaw cycles.
摘要
- 通过放射免疫分析法测定了储存在4℃、20℃和37℃长达8天或反复冻融的人血浆样本中的内源性促黄体生成素（LH）、促卵泡生成素（FSH）、促甲状腺激素（TSH）、生长激素、催乳素和胰岛素。2. 在4℃时，所有激素的浓度至少8天保持稳定；在20℃时，只有LH、FSH和TSH在8天内保持稳定；在37℃时，只有TSH在8天内保持稳定。3. 除胰岛素外，所有激素在5次冻融循环中均保持稳定。
