PPT-Phage Vectors Bacteriophages

or phages are viruses that specifically infect bacteria Viral vectors are those in which gene of interest is incorporated in the genome of virus The phage particle attaches to the outer surface of bacterium and injects its DNA into the cell.

How to identify circularly permuted genomes, physical ends, 3’ overhangs, terminal repeats, and nicks.. Circularly Permuted Genomes. Some phages have circularly permuted genomes. This means a linear concatamer of phage DNA is synthesized, used to fill a phage head, then cut when the head is full. Generally, one head will fit more than 100% of a genome, say, 103-110%. This ensures that wherever the DNA is cut, at least one working copy of each gene is present.. By Monique Hunter. Bacteriophages or phages are viruses that infect bacteria.. In 1917, .

The M13 phage is a human-friendly bacteriophage that only infects bacteria cells. 1. . It’s a nanofiber-shaped phage with five different coating proteins wrapped around its DNA (Figure 1b). The M13 phage can be engineered to display the exogenous peptides on its surface. This phage display technique allows us to study the function of short peptides that are derived from the cell’s growth factors, or proteins. Additionally, M13 phage have the ability to self-assemble into organized films that look like which can serve as a matrix for a cell culture. The phage film matrix can give us a better understanding of the role of short peptides in growth factors. The traditional method of making phage films requires the use of a pipette to drop the negatively charged phage solution onto the poly-lysine (Figure 2). However, manually, the results are not replicable and the process is time consuming. In order to make more organized and repeatable phage films we use a programmable slide stainer machine (Carl Zeiss, Inc.) that can dip the slides into a each solution allowing time to dry and giving it the ability to agitate. Resultantly, we built phage films while varying soaking time, phage concentration, and the number of phage layers to determine the best conditions to form well-ordered phage films with the help of slide stainer..
