Cloning of pHis-GST-TEV (1030)
Purpose: to clone pHis-GST-TEV
Date: 2012-3-26 to 2012-4-11
Notebook: Xiaojing Wang
Page: 004206
Clone ID: 1030
Experimenters: Xiaojing Wang
Results


The bands show PCR product of 1030,

TEV-Nde1-F
atcatg CATATG GGAGAAAGCTTGTTTAAGGG

TEV-Xho1-R
(cagttaaggaagcgactcaatag ctcgag actgac)

gtcagtctcgagctattgagtcgcttccttaactg


Digest result:


digest PCR product and vector with Nde1+Xho1, run gel

the left bands show 1030 insert, the right bands show 1029 vector

gel purify, ligate, transform Top10,K+

Colony Screening


1032-1,-2,-3,-4 may be correct.

Select 1032-4 to sequence.


Wrong design
should not use TEV-Nde1-F
