Introduction
The Cold Fusion technology is a simple, rapid and highly efficient PCR cloning kit. It allows you to directly clone any PCR product(s) to any linearized expression vector, at any site. The PCR fragments can be generated by Taq DNA polymerase or other high fidelity DNA polymerases, with primers that are designed to have 15 bases of homology at the linear ends where the DNA-of-interest will "fuse". The linearized vector can be generated by PCR or restriction enzyme digest (single or double cut). With a one tube simple reaction format, a 5 minute incubation at room temperature, followed by 10 minutes on ice, your PCR product(s) rapidly and accurately fuse into the linearized vector in the desired orientation. The kit is so robust that multiple DNA fragments can be assembled simultaneously and cloned into one construct in a single step. The system is highly efficient, with more than a 95% positive cloning rate. A. Key Features

The competent cells provided with the Cold Fusion Cloning Kit has the following genotype:
F' {proAB+ lacIq lacZΔM15 Tn10(TetR) Δ(ccdAB)} mcrA Δ(mrr-hsdRMS-mcrBC) φ80(lacZ)ΔM15 Δ(lacZYA-argF) U169 endA1 recA1 supE44 thi-1 gyrA96 relA1 tonA panD Due to the presence of the Tn10 transposon element, which encodes the tetracycline-resistance gene (TetR), the competent cell will be able to grow in LB-Agar plates containing 10 µg/ml of tetracycline. Cloning of inserts into plasmids containing a TetR marker and transforming the competent cells in the kit will likely lead to the failure of the cloning reaction. In this case, we would recommend another high-quality competent cell that does not have built-in tetracycline resistance (TetR) for best results. www.systembio.com Cold Fusion™ Cloning Kit Cat. # MC010A-1, MC 100A-1, MC 101A-1 II. Protocol
A. Overview
B. Preparation of Linearized Vector
Complete linearization of the vector is critical to achieve a successful Cold Fusion cloning reaction. Incomplete
linearization of the vector will result in high background. The linearized vector can be generated by PCR or restriction
enzyme digest (single or double digest) and should be purified using a gel or PCR purification kit.
Due to the digestion efficiency, different restriction enzymes will generate different levels of background. In general, two enzyme digestion is better than a single enzyme digestion. The further the restriction sites are apart, the better the digestion efficiency. Increasing the enzyme digestion time and the digestion reaction volume will also help reduce the background. For many enzymes, we recommend incubate the digestion reaction between 3 hours and overnight in order to increase linearization and reduce background. Check the background of your vector by transforming 1g (10-100ng) linearized and purified vector into competent cells. If the background is high, continue digesting the remaining vector for a longer time after the addition of more restriction enzyme(s). We recommend digesting 2g vector in 50l reaction overnight. Use QIAGEN's QIAquick Spin Gel Extraction kit for gel purification and elute the DNA with 30l dH2O. 888-266-5066 (Toll Free) 650-968-2200 (outside US) System Biosciences (SBI) C. Primer Design
Forward Primer Design
The forward primer should contain 18-20 bases complimentary to the 5' end of your gene-of-interest plus 15 bases
corresponding to the vector. Depending on the purpose of your cloning, your primers might also need to contain a
Kozak sequence and/ or ATG start site.
Reverse Primer Design
Reverse primers should be made to the negative strand of DNA. Depending on the vector you are using, the 3' end
of the insert may need to contain a stop codon (TAG, TAA, or TGA). The 3' primer should contain 18-20 bases
complimentary to the 3' end of your gene-of-insert, plus 15 bases corresponding to the vector.
Introducing Restriction Sites
A restriction site can be introduced in the middle of the primer and can be the same as or different than the one used
to linearize the vector. For multiple DNA fragment joining, it is recommended that each PCR product shares 18
base pairs of homology.
D. PCR Requirements
 The PCR fragments for the cDNA-of-interest should be generated using Taq DNA polymerase or other high
fidelity DNA polymerase.  The melting temperature (Tm) should be calculated based on the gene-specific ends of the primer, NOT the  Specific PCR reaction conditions should be optimized for the cDNA-of-interest.  After completion of the PCR reaction, gel purify the appropriate band to remove any extra primers or primer dimmers that will inhibit the Cold Fusion reaction. We recommend the QIAquick PCR Purification Kit (Cat # 28106, Qiagen). E. Cold Fusion Reaction
Set up the following reaction in a 1.5 ml sterile reaction tube by mixing the following reagents gently and then spin
down briefly to collect the reagents at the bottom of the tube.

Linearized destination vector (10-100ng/l) l* dH2O * 2:1 or 1:1 molar ratio of insert: vector works well in the Cold Fusion reaction. For reactions with larger volumes of vector and insert (>8l of vector + insert), double the amount of reaction buffer and enzyme, and add dH20 for a total volume of 20l. When using Cold Fusion cloning kit for the first time, we strongly recommend that you perform the positive and negative control reactions in parallel with your Cold Fusion cloning reaction. The positive control 500bp PCR insert and linearized vector provided in the kit have already been purified. There is no treatment needed prior to the cloning reaction. Cold Fusion Reaction Incubation

Probable cause
Solution
Check primer sequences to ensure that they provide 15 bases of homology with the region flanking the insertion site. Optimize your PCR amplification reactions so that you generate pure PCR Use a different method to purify your PCR product. It is imperative to obtain as high a DNA concentration as concentration in possible in your Cold Fusion Both the PCR product and the linearized vector should obtained from product or linearized vector Do not add more than 10l of reaction mixture to 50l of competent cells. Too much reaction mixture reaction mixture inhibits the transformation. Handle the competent cells gently. Do not re-freeze cells after thawing. Quality of competent cells may be tested by poor handling of transforming a circular plasmid to determine cells' competency. Competent cells with a transformation efficiency of 1x109 cfu/ μg are recommended.

    TEAM ORGAN MARCH 27TH, 2009 Sara Moghaddam-Taaheri 1. SPECIFIC AIMS Though nearly 110,000 people are on the organ transplant waiting list, only 77 people receive organ transplants daily. The time an organ can remain outside the body plays a crucial role in the organ transplantation system. The current viability of hearts is limited to a mere four to six hours, due to the limitations of the common cold storage method. This limitation influences several key decisions, such as where a heart can be transported to, or where the surgery can be conducted. Current methods of cold static storage have reached their limits in storage time due to the extent of ischemia-reperfusion (I/R) injury induced during static cold storage. The extent of reperfusion injury is directly proportional to preservation time in cold storage, and research has shown that with static storage methods, heart storage time will not exceed six hours. This essentially means that the demands of the organ transplant list will not be met.
