A Tozzo Frios conta com uma vasta gama de produtos como: frios, laticA­nios, embutidos, enlatados, congelados e produtos a granel. The Q5® Site-Directed Mutagenesis Kit enables rapid, site-specific mutagenesis of double-stranded plasmid DNA in less than 2 hours (Figure 1).
The use of a master mix, a unique multi-enzyme KLD enzyme mix, and a fast polymerase ensures that, for most plasmids, the mutagenesis reaction is complete in less than two hours.
This kit is designed for rapid and efficient incorporation of insertions, deletions and substitutions into doublestranded plasmid DNA.
Substitutions, deletions and insertions are incorporated into plasmid DNA through the use of specifically designed forward (black) and reverse (red) primers. Ensure there is a clean PCR product by visualizing 2–5 ?l of the reaction on an agarose gel. Check that the transformation efficiency of the competent cells is ~1 x 109 colony forming units (cfu) per ?g. The Product Manual includes details for how to use the product, as well as details of its formulation and quality controls.
Yafeng Li, Delu Song, Ying Song, Liangliang Zhao, Natalie Wolkow, John W Tobias, Wenchao Song, Joshua L Dunaief (2015). The following is a list of Safety Data Sheet (SDS) that apply to this product to help you use it safely.

The kit utilizes the robust Q5 Hot Start High-Fidelity DNA Polymerase along with custom mutagenic primers to create insertions, deletions and substitutions in a wide variety of plasmids. The first step is an exponential amplification using standard primers and a master mix fomulation of Q5 Hot Start High-Fidelity DNA Polymerase.
A) Substitutions are created by incorporating the desired nucleotide change(s) (denoted by *) in the center of the forward primer, including at least 10 complementary nucleotides on the 3?side of the mutation(s). To take advantage of the exponential nature of the amplification reaction, the 5? ends of the two primers should align back-to-back unless deletions are being made (see Figure 3).
If more KLD reaction is added, a buffer exchange step, such as PCR purification, should be included prior to transformation.
To calculate transformation efficiency, transform 2 ?l of the provided control pUC19 DNA (100 pg) into 50 ?l of cells. The following file naming structure is used to name these document files: manual[Catalog Number]. Iron-induced Local Complement Component 3 (C3) Up-regulation via Non-canonical Transforming Growth Factor (TGF)-? Signaling in the Retinal Pigment Epithelium. This product is not intended to be used for therapeutic or diagnostic purposes in humans or animals. Our unique column design offers elution in lower volumes and eliminates buffer retention, resulting in high quality DNA for downstream applications. After PCR, the amplified material is added directly to a unique Kinase-Ligase-DpnI (KLD) enzyme mix for rapid (5 minutes), room temperature circularization and template removal (Figure 2). The second step involves incubation with a unique enzyme mix containing a kinase, a ligase and DpnI.


The reverse primer is designed so that the 5? ends of the two primers anneal back-to- back. For best results, primers should be designed and annealing temperatures calculated using NEBaseChanger™, the NEB online primer design software.
If the PCR yield is low, more product can be added to the KLD reaction, however a buffer exchange step, such as PCR purification, must be included prior to transformation. Together, these enzymes allow for rapid circularization of the PCR product and removal of the template DNA. B) Deletions are engineered by designing standard, non-mutagenic forward and reverse primers that flank the region to be deleted. Alternatively, the optimal annealing temperature could be determined using a gradient PCR followed by agarose gel analysis. C) Insertions less than or equal to 6 nucleotides are incorporated into the 5? end of the forward primer while the reverse primer anneals back-to-back with the 5? end of the complementary region of the forward primer.
Engineering the Caenorhabditis elegans genome using Cas9-triggered homologous recombination.. D) Larger insertions can be created by incorporating half of the desired insertion into the 5? ends of both primers. The maximum size of the insertion is largely dictated by oligonucleotide synthesis limitations.
