General description
甲酰胺是一种有机溶剂，能使核酸在室温下变性和复性。它尤其适合用在反应时间长以及高温通过断链和脱嘌呤作用等损害生物活性的实验中。甲酰胺降低了双链核酸的热稳定性，通常用于DNA复性或DNA-RNA杂交。甲酰胺浓度和反应温度决定了反应的特异性和速率。
Application
甲酰胺已用于：
原位杂交
原位杂交
- 用作RNA聚丙烯酰胺凝胶电泳的2X变性上样染料组分
- 在血管渗漏试验中，提取小鼠后肢的伊文思蓝染料
- 用作裂解和聚腺苷酸化活性试验所用的终止缓冲液组分
甲酰胺可使核酸双螺旋不稳定，通常可以 50% 的浓度，用于需要较低杂交温度的杂交实验。
Analysis Note

Aneuploidies are the most frequent chromosomal abnormalities in humans. Most of these abnormalities result from meiotic errors during the gametogenic process in the parents. In human males, these errors can lead to the production of spermatozoa with numerical chromosome abnormalities
