Cloning of double-stranded DNA (dsDNA) molecules into plasmid vectors is one of the most commonly employed techniques in molecular biology. Ligation Protocol with T4 DNA Ligase (M0202) Electroporation Protocol (C2989) NEBNext Quick Ligation Module Protocol (E6056) Removal of Single-Stranded Extension Protocol using Mung Bean Nuclease (M0250) Transformation Protocol (M0367) Transformation Protocol (M0370) Ligation Protocol for Cloning with Instant Sticky-end Ligase Master Mix (M0370) This process is often used to prepare short DNA sections for: The following table indicates the various controls:Receive the latest news, hot plasmids, discounts and more.Learn about the latest plasmid technologies and research tools.Have questions about your order, deposit, or a plasmid? For cloning more than one insert, we recommend NEBuilder ® HiFi DNA Assembly Products.
Thermo Fisher Scientific Inc. announces acquisition of QIAGEN N.V., a leading global provider of molecular diagnostics and sample preparation technologies. Schematic representation of single- and multiple-fragment cloning reactions using In-Fusion Cloning and ligation-based cloning with T4 DNA ligase.

It is okay to cut away some of the DNA, you just want to get the DNA to be as concentrated as possible. Use a Additional controls are encouraged, but may only be required for troubleshooting failed ligations. By continuing to use this site, you agree to the use of cookies.

The ratio of 1:1 (vector:insert) gives the best efficiency of ligation. To save your cart and view previous orders, sign in to your NEB account. Your profile has been mapped to an Institution, please sign back for your profile updates to be completed. However, for most standard cloning (where the insert is smaller than the vector) a 3 …
Combine 20–100 ng of vector* with a 3-fold molar excess of insert and adjust volume to 5 μl with dH 2 O. … After ligation, the insert DNA is physically attached to the backbone and the complete plasmid can be transformed into bacterial cells for propagation.The majority of ligation reactions involve DNA fragments that have been generated by The example below depicts the ligation of two sticky ends that were generated by EcoRI digestion:Before setting up the ligation reaction itself, it is important to determine the amount of cut insert and vector to use for the ligation reaction. Learn more about the function of ligation with our quick tutorial animation.Ligation of blunt ends and single-base overhangs require optimized reaction conditions.The optimal reactant ratio is contingent upon the downstream application.Find out how the downstream application dictates the best reaction conditions for ligation.Polyethylene glycol (PEG) is an important reagent in ligation reactions, find out why.You have been idle for more than 20 minutes, for your security you have been logged out. Ligation Independent Cloning (LIC) Scarless cloning with Type II restriction enzymes and T4 polymerase: pLKO.1 - TRC Cloning Vector: Cloning protocols for using the pLKO.1 vector, a backbone used by the RNAi consortium for targeting human and mouse genes. Ligations can be performed in any of the four standard restriction endonuclease NEBuffers or in T4 Polynucleotide Kinase Buffer (NEB #B0201) if they are supplemented with 1 mM ATP. If you run into any problems registering, depositing, or ordering please contact us at Open collection of AAV data generously shared by scientistsBasic analysis for a user-entered sequence; includes restriction sites and mapDigital collection of empty plasmid backbones from publications and commercially available sourcesThe final step in the construction of a recombinant plasmid is connecting the insert DNA (gene or fragment of interest) into a compatibly digested vector backbone. You may wish to do a second ligation reaction at a ratio of 1:3 (vector:insert), if you are concerned about the accuracy of your DNA concentrations.
