What are the best ways to reduce generation of chimeric molecules during PCR?

The chimeric molecules generated during PCR are really bad for our study on recombination, since the chimeras look exactly like recombination. I wonder what and how (would be better if protocol is...

What percent of template can be synthesized during PCR?

For example, the parameters for PCR are denaturing at 95, annealing at 58 and elongation at 72, while the melting temperatures of primers are around 60.

Does anyone have experience about the efficiency for linear DNA synthesis?

We are trying to synthesize mouse DNA using "linear" synthesis in very limited number of cycles without "denaturing". Do you have any experience for linear DNA synthesis, especially about the the...

Is there a way to reduce the interference from genomic DNA on your template-primer pairing?

For example, whether long DNA fragments or shorter ones (such as with restriction enzymes) interfere with the pairing of the primers to the templates of interest with different efficiency or not.

Is digestion of genomic DNA helpful to increase the pairing of primer to a specific genomic region of interest?

We are trying to test the efficiency of pairing of a primer to a region of mouse genome. We are thinking of digesting genomic DNA before pairing and wonder whether the longer or the shorter...

I can detect my protein but the encoding DNA sequence has stop codons within. Should I ignore the stop codons?

I constructed a synthetic DNA library (scFv, VH-VL orientation) with a 3' reporter and 8x histag. I cloned and expressed this gene following which I performed an ELISA. The ELISA results suggested...
