一般描述

SYBR® Green I是一种特制的不对称花菁染料,用于检测核酸。这种成分由N-烷基化苯并噻唑或苯并噁唑环系统组成,通过单次甲基桥连接吡啶鎓或喹啉鎓环系统。SYBR Green I与dsDNA的小沟结合,激发波长480 nm。其荧光发射峰波长为520nm。

应用

SYBR® Green I核酸凝胶染色剂已用于:
  • dsDNA定量
  • 聚合酶链式反应(PCR),用于DNA染色
  • Comet测定技术
  • 评估精子膜的完整性
  • 扩增DNA 目视检查(环介导等温扩增(LAMP)法)
  • 用作流式细胞术中的荧光染料
  • 实时定量逆转录聚合酶链式反应(qRT-PCR),用于逆转录cDNA染色

特点和优势

  • 用于在电泳后对琼脂糖或聚丙烯酰胺凝胶中的双链DNA染色的超灵敏染色剂
  • 它还可以检测变性琼脂糖/甲醛和聚丙烯酰胺/尿素凝胶中的ssDNA和RNA,无需任何预洗涤步骤
  • 在 Ames 试验中,它的致突变性比溴化乙锭小
  • 它对寡核苷酸的检测灵敏度是溴化乙锭的 50-100 倍
  • 适用于 DNA 数量有限的许多应用
  • SYBR® Green I 与 DNA 的结合不会抑制许多常见限制性内切酶的活性,包括 Hind III 和 EcoR I
  • 这种染色剂无需通过凝胶酶解和连接技术去除
  • SYBR Green I 是溴化乙锭染色的绿色替代产品

储存及稳定性

将产品储存在–20 °C。稀释后的染色溶液避光可在2–8 °C保存数周或室温保存3-4天。

  5. Will Product S9430, SYBR® Green I nucleic acid gel stain, stain DNA that contains deaza-G modified nucleotides in place of guanisine?  

    Product S9430, SYBR® Green I nucleic acid gel stain, will poorly stain DNA containing deaza-G modified nucleotides in place of guanisine.  A way around this issue would be to use a mixture of deaza-G modified nucleotides with guanisine.  This will allow for better staining. 

  6. My question is not addressed here, how can I contact Technical Service for assistance?
