Maximize your detection sensitivity with the GelStar™ Photographic filter, designed for use with GelStar™ Nucleic Acid Gel Stain. The GelStar™ Photographic filter is a 3 inch square Wratten® #9 filter designed to optimize detection sensitivity when using black and white photography on Polaroid® camera based systems.
A highly sensitive fluorescent stain for detecting both DNA and RNA. Maximum sensitivity, detect as little as 20 pg of dsDNA or 3 ng of RNA You can choose to either add GelStar™ Stain to your agarose solution prior to casting or to post stain your gels. GelStar™ Nucleic Acid Gel Stain exhibits exceptional signal-to-noise ratio with minimal background.
Versatile, use for agarose or polyacrylamide gel electrophoresis, ideal alternative to silver staining
Ultimate user flexibility, add GelStar™ prior to gel casting or post stain, no destaining required
Complete staining solution for all types of nucleic acids
Detect fragments with either a standard 300 nm UV transilluminator or the Clare Chemical Dark Reader™ transilluminator
Document your results with either Polaroid™ or CCD-based camera systems
DNA荧光染色剂，灵敏度可检测到低至60pg的条带。A highly sensitive fluorescent stain for detecting dsDNA and oligonucleotides in agarose and polyacrylamide gels. Because SYBR® Green's fluorescent signal is greatly enhanced when the dye is bound to nucleic acids, gels stained with SYBR® Green I exhibit an excellent signal-to-noise ratio with no background fluorescence. For maximum performance, gels should be poststained. SYBR® Green I is ideal for gel-based detection of small amounts of DNA in low copy/target number PCR products, apoptosis studies, and heteroduplex analysis. Detection Limits: dsDNA at 300nm transillumination: 60 pg, Oligonucleotides at 300nm transillumination 1-2 ng
For ssDNA and RNA, SYBR® Green II offers all the advantages of SYBR® Green I and is ideal for non-isotopic detection of DNA mutations by single-stranded conformation polymorphism (SSCP) analysis.

SYBR Green I 核酸凝胶染料是目前检测琼脂糖凝胶和聚丙烯酰胺凝胶中双链DNA（dsDNA）和RNA（dsRNA）的最灵敏的染料之一。SYBR Green I 适用于各种电泳分析，使用简单，灵敏度高（在497 nm的透射光下，灵敏度高于EB 染色法10～25 倍），可以检出20pg 的DNA。SYBR Green I 核酸染料与核酸结合后的最大吸收峰在蓝绿可见光区，适用于使用可见光系列仪器对染色结果进行观察。同时，其在紫外区300nm～380nm 也有一个吸收峰，使得其染色结果也可以使用紫外光相关设备进行分析。在300 nm的透射光下，低至60 pg 的dsDNA 条带也能被SYBR Green I 染料检测。这种灵敏度比传统300 nm 透射光下的溴化乙锭（EB）染色至少高了25 倍（图1）。SYBR Green I 染料对于检测寡核苷酸也非常灵敏，能在15%的聚丙烯酰胺凝胶上检测低至1-2 ng 的合成24 聚体，比溴化乙锭的灵敏度高了50-100 倍。同时在不与dsDNA 结合时背景几乎可以忽略。由于SYBR Green I 染料的DNA 结合力强，可将染料加入DNA预先与DNA 包被电泳（电泳前染色）也可在制备凝胶时预先加入SYBR Green I 染料制备凝胶（电泳中染色），以及电泳后染色对DNA 进行染色，此外，SYBR Green I 染料与DNA 的结合不会抑制多种常见的限制性内切酶的活性，包括Hind III 和EcoR I，也不会干扰Southern 杂交分析。同时SYBR Green I染料还可用于DNA 的胶回收实验。详细请联系4008513777.
