1030-pHis-GST-TEV
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
