One key difference is the plasmid dna must be released from the bacteria in order to serve as pcr template. Dealing with this and a few other colony pcr tips are highlighted below. Existing account holders still have account access.

This post along with a future companion post on mammalian vectors will catch you up on the core replication and resistance features. Setting up colony pcr reactions is nearly identical to preparing a standard pcr reaction. Coli cell but vectors can be widely utilized across many different cell types and each one requires different elements for vector propogation.

However for most standard cloning where the insert is smaller than the vector a 3 insert.

Addgene dna how. This website and its contents will remain available for reference purposes. Previously accepted orders will be processed until completion. The volume of vector dna and insert dna used in the ligation will vary depending on the size of each and their concentration. 1 vector molar ratio will work just fine.

We recommend around 100ng of total dna in a standard ligation reaction. These days many labs have a nanodrop which is a very small spectrophotometer that can accurately read dna concentration and purity in as little as 1μl. Combine template primers polymerase and dntps and then incubate with a standard pcr thermocycling program. Invoices are still due net30 days upon receipt.

Protein maximally absorbs at 280nm and the ratio of nucleic acid to protein 260 280 is generally used as an indicator of the purity of dna samples. Addgene millipore sigma dharmacon other commercial vendors and the originating labs. In our first few plasmids 101 posts we focused mainly on the elements required for plasmid maintenence within an e.
