Please see the link below to review the product datasheet. Note that the prepration instructions require the addition of the entire vial (6.5 mL) of equilabration buffer to the contents of the product. Aliquot immediately after the gentle mixing step. During the 2 - 4 hour incubation period the mixure will phase separate. At this point the aliquots may be stored for long term use according to the instructions.

應用
对于需要更高 pH 值的应用，例如大的完整基因组 DNA的分离，建议添加平衡缓冲液。
包裝
随配 P3803 和一瓶单独的平衡缓冲液，用于将苯酚相调节至 pH 8.0 ± 0.2。
適合性
这批苯酚：氯仿：异戊醇 25:24:1 采用从大肠杆菌中提取 的pBR322 DNA 的粗制品进行了测试。 根据琼脂糖凝胶电泳评估，提取的 DNA 没有降解或浓度降低。 采用相同的操作程序处理纯化的 pBR322 DNA 和 λ Hind III 消化 DNA。 根据琼脂糖凝胶电泳评估，纯化的制剂没有检测到降解或浓度降低。
準備報告
将小瓶平衡缓冲液的全部内容物添加到大瓶苯酚：氯仿：异戊醇中。 在使用前轻柔地混合并使相实现分离，大约 2-4 小时。 这会将苯酚溶液的 pH 值从 6.7± 0.2 调整到 8.0± 0.2。
其他說明
添加平衡缓冲液后，产品可稳定 6 个月，而不添加缓冲液可稳定 2 年。 在添加平衡缓冲液后，在 -20 °C 下避光储存可将保质期延长至 1 年以上。

I ordered Product P2069, Phenol:Chloroform:Isoamyl Alcohol 25:24:1; I got one bottle of the Phenol:Chloroform:Isoamyl Alcohol and one bottle of B5658, Equilibration buffer. When and how am I supposed to use the B5658?
1 answer-
B5658 is a Tris buffer that is used to raise the pH of the phenol:chloroform:isoamyl alcohol mixture, to make it suitable for isolation of genomic DNA. The contents of the two bottles need to be well mixed. Then allow the mixture to separate; this may take 2-4 hours. This procedure should raise the pH of the phenol phase from 6.7 to about 8.0. Only one "treatment" is needed. This solution should be stable for up to 12 months.

There is an Equilibration Buffer (Product B5658) that is included with Product P2069, Phenol:Chloroform:Isoamyl Alcohol 25:24:1. Is B5658 also available separately?
1 answer-
No, it is only available as part of P2069.

I see that you list two equilibrated Phenol:Chloroform:Isoamyl alcohol products. When should I use Product P3803, and when should I use Product P2069?
1 answer-
In short, P3803 is for RNA work, and P2069 is for DNA work. Product P2069 consists of one bottle of Product P3803 and one bottle of Product B5658. The B5658 is added to the P3803 to raise the pH of the organic phase from 6.7 to 8.0; pH 8.0 is not suitable for RNA work, because RNA can degrade at the higher pH.
