3×GelstainRed Prestain上样缓冲液升级款

GelstainRed是一款非常灵敏、稳定，且安全无毒的新型核酸染料，它可以完全替代高诱变性的EB。3× GelstainRed Prestain上样缓冲液升级款是一款包含示踪染料以及GelstainRed的凝胶Loading Buffer。这款预染缓冲液包含两种蓝色电泳示踪染料，在1%的琼脂糖凝胶中，分别指示1.5 Kb和200 bp的电泳条带。该产品可以直接与DNA样品混合后上样，进行凝胶电泳实验，无需提前在配制琼脂糖凝胶中加入核酸染料，因此更加方便快捷。 GelstainRed和EB具有几乎相同的光谱，因此GelstainRed可以在不改变现有成像系统的条件下代替EB。此外，GelstainRed还可兼容基因测序和克隆等下游一系列操作。使用商业化的DNA凝胶提取试剂盒、或者采用酚/氯仿抽提法、乙醇沉淀法等可以有效去除与DNA结合的GelstainRed。 使用方法： 1. 根据实验方案配置一定浓度的琼脂糖凝胶。注意在凝胶配置中，无需添加 EB、GelstainRed 等任何染料。 2. 简单涡旋并离心 3×GelstainRed Prestain 上样缓冲液升级款，将其与 DNA 样品按 1:2 比例混合。 3. 按标准程序加样，进行 DNA 凝胶电泳实验。 4. 在 UV 透射仪下观察电泳条带。使用 EB 滤光片，或 SYBR Green、GelStar 滤光片观察凝胶，同样可以得到较好结果。 注意事项： 1. 使用前请将产品瞬时离心至管底，再进行后续实验。 2. TAE和TBE导电性能存在差异，如需缩短电泳时间，可选用TAE电泳缓冲液。 3. 电泳时电压不宜过高，一般为120 V左右，但具体条件视不同实验室而定。 4. 当上样浓度较大时，该产品也可以达到较理想的效果。 应用范围： 核酸凝胶电泳中核酸样品染色 Gelstein red is a very sensitive, stable, safe and non-toxic new nucleic acid dye, which can completely replace EB with high mutagenicity. three × Gelstein red prestain loading buffer upgrade is a gel loading buffer containing tracer dye and gelstein red. This pre staining buffer contains two blelectrophoretic tracer dyes, which indicate electrophoretic bands of 1.5 KB and 200 bp, respectively, in a 1% agarose gel. The product can be directly mixed with DNA samples and loaded for gel electrophoresis experiments without adding nucleic acid dye to the prepared agarose gel in advance, so it is more convenient and fast. Gelstein red and EB have almost the same spectrum, so gelstein red can replace EB without changing the existing imaging system. In addition, gelstein red is also compatible with downstream operations such as gene sequencing and cloning. Gelsteinred bound to DNA can be effectively removed by using commercial DNA gel extraction kit, phenol / chloroform extraction method, ethanol precipitation method, etc. Instruction： 1.Configure a certain concentration of agarose gel according to the experimental program. Note that in the gel configuration, there is no need to add any dyes such as EB, GelstainRed, etc. 2.The 3 × GelstainRed Prestain loading buffer was upgraded by simple vortex and centrifugation, and it was mixed with the DNA sample at a ratio of 1 : 2. 3.DNA gel electrophoresis experiments were carried out according to the standard procedure. 4.Observe the electrophoresis bands under the UV transmission instrument. Using EB filter, or SYBR Green, GelStar filter to observe the gel, also can get better results. Matters needing attention： 1. please centrifuge the product to the bottom of the tube immediately before use, and then conduct subsequent experiments. 2. TAE and tbe have different conductivity. If it is necessary to shorten the electrophoresis time, Tae electrophoresis buffer can be selected. 3. the voltage should not be too high during electrophoresis, generally about 120 V, but the specific conditions depend on different laboratories. 4. when the loading concentration is large, the product can also achieve ideal results.
