Figure 2From: A unified framework for managing provenance information in translational researchSchematic representation of the procedure to knock out both the alleles of a gene during the transfection process. The alleles for a particular gene are knocked out to totally ablate (or atleast reduce) the function of the gene and are replaced with the selected antibiotic (neomycin or hygromycin) resistance gene during the transfection experiment process.Back to article page
