产品信息
Ph.D.-12 噬菌体展示肽库试剂盒 v2 的制备原理是将随机十二肽组合库融合表达于 M13 噬菌体次要外壳蛋白(pIII)的 N 端(5-9)。这种肽后跟随一个直接位于野生型 pIII 序列之前的短间隔序列(Gly-Gly-Gly)。该库包含约 10 亿个电穿孔序列,在提供的 10 μl 噬菌体中经扩增一次,每个序列即可产生约 100 个拷贝。
展示肽形式:X12-GGG-野生型 M13 pIII

优势和特性
Features
- 即用型复杂噬菌体库;表型与基因型之间的内在关联支持在单个微孔板或 Eppendorf 试管中筛选数十亿个克隆
- 对照淘选实验无需执行封闭步骤,可避免噬菌体与塑料结合物发生非特异性结合
- 使用 Protein G 磁珠进行对照淘选实验,可减少繁琐的板/孔冲洗步骤
- 随机区域的长度(12-mer)便于形成分子内二级结构,并在结合位点之间留出序列间隙
- 无需使用辅助噬菌体进行扩增
- 利用简单明了的分子生物学和无菌培养技术,可在不到一周的时间内获得肽结合序列
- 提供的 -96 gIII 测序引物(500 pmol)可进行 50 次以上测序反应

注意事项
- 若要长期贮存(> 30 天)E. coli K12 ER2738,推荐贮存于 -80℃。
- Protein G 磁珠应贮存于 4℃,以防冻坏。
- 初代试剂盒(NEB #E8110)和二代试剂盒(简称 v2;NEB #E8210)均包含相同的 Ph.D.-12 噬菌体展示肽库组份(NEB #E8111)。
- M13 兼容大多数缓冲液条件;不过,洗脱缓冲液可能受制于扩增大肠杆菌所需的培养条件。如果使用二代测序方式,则无需通过扩增来富集噬菌体池。浏览现有文献了解操作流程。
- 提供的 -96 gIII 测序引物(500 pmol)可进行 50 次以上测序反应。

FAQs
- What is the difference between the original and version 2 (v2) Phage Display kits?
- Which of the three ready-made libraries should I choose?
- What is the difference between the three ready-made libraries?
- Can a different bacterial strain be used with the Ph.D.™ Phage Display?
- No plaques are visible when titering using a Ph.D.™ Phage Display Library.
- I am using Ph.D.™ Phage display and the amplified phage titer is low.
- I am using Ph.D.™ Phage Display and the phage DNA templates do not yield a readable sequence.
- I am using Ph.D.™ Phage Display and the sequencing templates do not run where they should on a gel.
- I am using Ph.D.™ Phage Display and after 4 or more rounds of panning all clones are wild-type phage (white plaques).
- When performing an experiment using Ph.D.™ Phage Display, the ELISA indicates that background binding to the plate is as high as binding to the target.
- When using the Ph.D.™ Phage Display, panning yielded a consensus sequence, but no ELISA signal.
- Where can I find references for Ph.D.™ phage display libraries?
