Editing 1916-pEC2-M-SssI (section)

=== cloning ===

Date: March 10,2015

use the primers 1916-M-SssI-1-1 and 1-6 to do a PCR I;&nbsp;

use the primers 1916-M-SssI-1-7 and 2-14 to do a PCRII;&nbsp;

Combined two PCR together

Then digest PCR product with NdeI and XhoI. Then clean up the digestion product. and ligation. transformation. selection 10 colonies to screen (PCR). 5 Colonies PCR result is great, take the five colonies to innoculate and extact plamid and Digestion.&nbsp;

No product was found. Could be caused by the enzyme not working, use the home-made NdeI to test again.

Actually, none digestion could be caused by adding wrong amout buffer.

Sent the sequencing, the result have the clone. But there is other mistake happening on oligo 2-13.

do the PCR 1-1 to 2-12,

Then purified the PCR puduct, use oligos 1-1, 2-12, and oligos 2-13 (1uM).

Digest the PCR product and vector 2015 PEC2 by NdeI/XhoI. purify the digested vector from Gel, also purify the PCR insert.

ligation, transformation. Screening:

&nbsp; No.5 is the positive colony. Send to seqence 5-2-2015, and there is a mistake on oligos.

&nbsp;1916-M-SssI-1-12/1-13.

Rescreening other 8 colonies:

#3 is the positive colony. Sent it to sequence on May 7 2015.
