ArsA

Profile

Name: ArsA

Base Pairs: 2564 bp

Origin: Escherichia coli (strain: LST424C, nat-host: Homo sapiens)

Properties: Gene technology for protecting patented bacterial strains

ArsA ATPase is the catalytic subunit of the pump protein, which combines the hydrolysis of ATP with the movement of arsenic and antimony through the transmembrane ArsB protein. The organism Escherichia coli excretes arsenic from the body through this gene pathway, thereby reducing the poisonous effect of arsenic.

Experimental approach

Production, purification, and sequcing analysis of recombinant ArsA-amilGFP

Figure 1: Gel Electrophoresis Results of PCR of amilGFP Genes..

Figure 1 shows gel electrophoresis results of amilGFP PCR. Column M is a 2K marker ladder. Columns 1-6 are PCR products of amilGFP genes. All 1-6 columns displayed successful results at 700bp which could be used for later experiments. 

Figure 2: Gel Electrophoresis Results 1 of Colony PCR of ArsA..

Figures2 show the result for colony PCR identification on the E.coli with ArsA inserted that were cultivated previously. The purpose is to examine whether the E.coli contains expected gene segment of ARSA.
