Lab 208

Main purpose

• Add USER endings to HAO gene extracted from Nitrosomonas europaea

Who was in the lab

Henrike

Procedure

Repeat HAO USER PCR from yesterday with same conditions and programs

Template: HAO extraction fragment -isolated from Nitrosomonas europea- (purified from PCR run on 04.09)

Primers: 18a & 18b

Two versions, one with 5% DMSO and one with 3% DMSO and two programs: Touchdown (62C -> 55) and a single annealing temperature of 59C.

PCR reaction master mix

• Add 49 ul of the master mix, and
• Add 1 ul DMSO (for the 5%) or 1 ul of MQ (for the 3%)

User reaction

was performed with HAO User fragment that was purified yesterday (but had low concentration) and pZA21::ara (promoter from the Biobrick K808000) and pZA21 with a tight arabinose promoter (from our SPL). Also Nir 1 User and Nir 2 User were ligated into the pZA21 ara tight for Nir. Negative controls were made for all three backbones.
