DbpA-(G2S)3-Bst

Introduction

The fusion protein obtained by linking the N-terminus of Bst to the C-terminus of DbpA via a (G2S)3 linker.

Experimental Results

The length of DbpA-(G2S)3-Bst DNA was 2013 bp, which is approximately 2020 bp after adding homology arms to both ends for PCR cloning. We isolated the target DNA by gel extraction for subsequent reactions.

Figure 1. PCR assembled Bst fusions. The first lane was loaded with DNA ladder, sizes were marked on the image. The brightest band of 750 bp was about 100 ng, and other bands about 50 ng. Lanes with correct sized amplified DNA were labeled. The third lane (lane-2) was loaded with DbpA-(G2S)3-Bst DNA.

After ClonExpress homologous recombination reaction, Fast-T1 competent bacteria were transformed with reactants, and spread onto LB plates with antibiotics. We picked colony after 16 h culturing plates at 37℃. We further grow clones in 2 ml LB liquid medium with antibiotics, 37℃ shaking overnight.

Mini-prep was performed the following day, and the resulting plasmids were sent to Sanger sequencing.
