- ---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
- KAH109/pT7CFE1-CHis: KAH109/(E/P)/1132 + pT7CFE1-CHis/(E/P)/3600
- KAH111/pT7CFE1-CHis: KAH184/(E/S)/1123 + "
- KAH112/pT7CFE1-CHis: KAH187/(E/S)/1123 + "
- KAH115/pT7CFE1-CHis: KAH188/(E/S)/931 + "
- KAH148/pT7CFE1-CHis: KAH189/(E/S)/967 + "
- KAH150/pT7CFE1-CHis: KAH190/(E/S)/967 + "
- KAH151/pT7CFE1-CHis: KAH191/(E/S)/967 + "
Note: KAH109 is being re-done as an internal control to trouble-shoot the ligation
Note: KAH111-KAH151 are all cut and purified already

> 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)
