====Result of OZ052 and OZ123 Transformation====

[[#Transformation for OZ plasmids|Last Friday]] we plated out the transformed bacteria for the two OZ controls in 10 ul and 50 ul volumes.  They both yielded colonies, but the 10 ul plates only had a handful while the 50 ul plates had around 15-20 colonies each.  We picked four colonies from each plate and grew them in LB/spec so that tomorrow we can perform a miniprep and send them off for sequencing.  We should know the final verdict by Wednesday regarding which ones are good or bad.

We got the sequencing results back from last Friday, and took the following colonies to make into glycerol stock solutions: 77.1, 79.2, 80.1, 81.1 (x2 for both FH bottom and Myc 198), 82.1, 83.4, 84.1, Zif268.  These colonies are a subset of the "good" colonies from our [[Lab_Notebook:_July#Sequencing_Results|sequencing results]] from Sunday.  We mixed 120 ul of bacteria in mid-log with 300 ul of 80% glycerol to make the final solution, which was stored at -80 degrees C.

*Results: the product was really really really faint--primer dimers were by far the bulk of the product.  We realized this is probably because one of the primers includes a Not1 restriction site, which is palindromic, 8 bases long, and all Cs and Gs.
