Biotin 3' End DNA Labeling Kit

1. 生物素3’末端DNA标记试剂盒( Biotin 3’ End DNA Labeling Kit )是一种通过Terminal Deoxynucleotidy Transferase( TdT )把生物素标记的dUTP添加到DNA 3’末端的试剂盒。通常DNA的3’末端被标记后不会干扰杂交反应,也不会干扰基于序列特异性蛋白结合的EMSA检测;因此生物素标记的DNA探针可以用于常规的Northern,Southern,EMSA(即gel shift)以及colonyhybridization或原位杂交等。2.Terminal Deoxynucleotidy Transferase( TdT )可以在不依赖于模板的情况下催化在DNA的3’-OH端加上dNTP的反应。关于TdT催化双链DNA末端加dNTP的反应效率,3’端突出的双链DNA要比平端或3’端缩进的双链DNA高很多。TdT催化单链DNA末端加dNTP的反应效率要比双链DNA高很多。在适当的条件下,TdT也可以催化RNA3’末端加NTP的反应。3.DNA末端加dNTP的反应效率要比双链DNA高很多。在适当的条件下,TdT也可以催化RNA3’末端加NTP的反应。4.本试剂盒适合标记纯化的单链DNA,如果用于标记EMSA探针,可以在单链标记后再进行退火。5.本试剂盒中提供了已经用生物素标记好的Biotin-Control Oligo,可以用作检测DNA标记效率的对照。6.如果每个标记反应的探针量为5pmol,本试剂盒可以用于20个标记反应。
