Every hard-core biologist knows designing the perfect construct can be a complex puzzle to solve. This challenge, if successful, can be extremely satisfying but can also drive you crazy for weeks. Luckily, Dr. Daniel Gibson and his colleagues at the J. Craig Venter Institute designed a new easy-to-use cloning method. Better yet, this system allows…
Do you know your transfections from your transductions? We explain the differences between three of the most commonly used ways of introducing foreign DNA.
What Is Alternative Polyadenylation? Processing of mRNA and its regulation plays a fundamental role in gene expression. As science progresses, alternative polyadenylation takes center stage in the undercurrents of gene expression. 1,2 Polyadenylation is part of the pre-mRNA maturation process and involves polyadenylation of the 3’ end of the emerging RNA. This process happens to…
One of the most crucial steps in any cloning procedure is the preparation of the vector. Get it wrong and your chances of success will be drastically reduced. The overall aim for a good vector preparation is to obtain a fairly concentrated stock of undamaged, fully digested plasmid DNA that is free from contaminants. Missing…
