DNA shuffling by molecular breeding was first reported in 1994 by Willem P.C. Stemmer. He started by fragmenting the β-lactamase gene that had been amplified with the polymerase chain reaction (PCR) by using DNase I, which randomly cleaves DNA. He then completed a modified PCR reaction where primers were not employed which resulted in the annealing of homologous fragments or fragments with similar sequences. Finally, these fragments were amplified by PCR… WebDNA family shuffling of the parental sequences using the the method described by Crameri et al 19 generated a library "diversified" in the region between amino acids 60 and 224 of the mature protein. dr mindell goji juice

WebDNA family shuffling is a powerful method for enzyme engi-neering, which utilizes recombination of naturally occurring functional diversity to accelerate laboratory-directed evolu-tion. However, the use of this technique has been hindered by the scarcity of family genes with the required level of sequence identity in the genome database.

"Web2.2.1 DNA shuffling and family shuffling. Stemmer introduced DNA shuffling, the first homologous recombination method, in 1994 [5, 6]. DNA shuffling involves the digestion of a gene by DNaseI into random fragments, and the reassembly of those fragments into a full-length gene by primerless PCR: the fragments prime on each other based on ...
