provides kits, reagents, instruments, and services that help researchers explore questions about gene discovery, regulation, and function. It is often caused by mixing all the reagents and leaving them cold for too long then the bases near each 3prime end of the primers anneals at room temperature and as the enzyme is active also at room temperature it will extend each primer to make the p=d double stranded.Takara Bio USA, Inc. You usually do not see p-d in well designed primers like primer3 or when you are using a hot start enzyme for the amplification. It runs as a diffuse band because it is small and thermal diffusion has a strong effect on it. p-d is very short (less than 50bp) so traps very little ethidium bromide so when you see p-d you really have a lot of it. Often you see good amplification of samples and there will be nop-d but if there is visible p-d there will be poor amplification as the primer is being removed from the reaction. Primer dimer is frequently seen in a proper negative control because the primers should have nothing to do. This would tell you if your ligation has a problem or if it was the transformation step. Designed an internal primer so the PCR will be easier. For troubleshoot you can check your ligation using PCR with one primer for the vector and the other for your insert. I found that use too much ligation product could reduce the yield. You can also try different concentration of ligation product. You also can try electroporation ( this is better if the vector size is big), recover with SOC instead of LB (remember to pre-warm SOC and LB plat at 37oC). For transformation you can try one shot Top10. You can either do a blind cut or sybgreen safe. Make sure you don't use ethidium bromide to dye the DNA while you gelpurify your digestions. For PCR you can try cloneamp ( ) or ( ) optimize PCR condition using touch down PCR. It will be quite difficult cloning cause your insert is rather big.
