Plasmids 101: How to Verify Your Plasmid Using a Restriction
Aug 28, 2014 · Diagnostic digests can be used to confirm the rough structure of the plasmid based on the predicted sizes and organization of different features within the plasmid. Restriction analysis can also be used successfully even if you don't have the full plasmid sequence.
Plasmid Cloning by PCR - Addgene
PCR based cloning is incredibly versatile and allows for nearly any piece of DNA to be placed into a backbone vector of choice with minimal limitations.
Plasmids 101: Control Plasmids - Addgene
To illustrate the importance of control plasmids, we will take a step beyond discussion in the abstract and follow an example of a plasmid-based experiment, delineate its requisite control plasmids, and discuss why these control plasmids are …
Addgene: Protocol - How to Perform a Diagnostic Digest
May 18, 2018 · The goal of a diagnostic digest is to cut your plasmid into specific sized pieces and analyze the resulting fragments by gel electrophoresis. The pattern of the fragments on the gel can indicate if the plasmid contains the expected size insert.
5 screening methods every scientist should know | Thermo Fisher ...
Colony screening with Polymerase Chain Reaction (PCR) is the most rapid initial screen to determine the presence of the DNA insert. Colony PCR involves lysing the bacteria and amplifying a portion of the plasmid with either insert-specific or vector-specific primers.
8.5: Cloning DNA - Plasmid Vectors - Biology LibreTexts
Jun 20, 2023 · Molecular biologists use plasmids as vectors to contain, amplify, transfer, and sometimes express genes of interest that are present in the cloned DNA.
Plasmids 101: Screening Strategies Used in Plasmid Cloning
Sep 15, 2020 · Plating the transformation on ampicillin plates containing X-gal allows you to identify cells that took up the vector and distinguish between plasmids that contain the gRNA (white) from those that do not (blue). Let’s take a look at a few screening methods.
Blue-White Screening & Protocols for Colony Selection
Ligation: ligation of foreign DNA into MCS of the plasmid vector; Transformation: introduction of plasmid vector with foreign DNA insert into competent E. coli; Screening: blue-white screening to identify recombinant bacterial colonies

Vector Manufacturing and Testing for Gene and Cell Therapy Applications
Nov 1, 2014 · Plasmids being produced in bacteria are tested for sterility and endotoxin levels. Similarly, the vector product requires testing for adventitious agents, purity, genetic identity, as well as potency before its release as a drug substance for transduction of cells ex vivo.
