[[Image:1584+1674 clone 2-15-2013.JPG]] 

subclone into 1629 pCold-GST-(3C) from 1661 pT7A3-MBP-(3c)-NRF2 using Nde1 + Xho1 

 

=== Colony Screening ===

Date: 2013-2-18

Make miniprep and digest with Nde1 + Xho1

[[Image:1674 1611 2013 2 18 1.JPG]][[Image:1674 1611 2013 2 18 2.JPG]] 

Only one clone, but it may be good. 

[[Image:1657 clone 2-19-2013.JPG]] 

the last lane is #1674 digest with Bgl11 

== '''Result intepretation/Summary''' ==

== '''Conclusion''' ==

Not good. Forward primer has an extra G, will not  express

== '''Cloning of 1674-pCold-GST-(3c)-NRF2''' ==

'''Purpose:''' Redo Cloning of 1674-pCold-GST-(3c)-NRF2, previous cloning did not produce expression clone due to bad design of F primer.
