PcTF Subcloning in E. coli

11/16/12

---Karmella 13:51, 16 November 2012 (EST): Here is my suggested procedure for trying the PcTF fusion cloning...

Assemblies: Shown as Part/cuts/purified fragment size

Note: KAH109 is being re-done as an internal control to trouble-shoot the ligation
Note: KAH111-KAH151 are all cut and purified already

> Digest (Fermentas FD)

> Measure concentration(s)

Sample	OD260	260/280	ng/μL
1. pT7CFE1-CHis (E/P)	---	---	---

> Ligations (trouble shooting suggestions)

Note: Use 50 ng of vector this time (instead of 20)
Note: Use a 3:1 ratio of insert to vector... x μL insert = 3 * (bp of insert/ bp of vector) * 50 ng vector / (concentration of insert ng/μL)
