pUC 118/119 Vectors

The pUC118 and pUC119 vectors are highly useful tools in genetic engineering and molecular biology, specifically designed for the production of single-stranded DNA (ssDNA). Single-stranded DNA plays a critical role in a variety of genetic research and therapeutic applications, making these vectors a vital asset in labs working on gene cloning, mutagenesis, and other molecular studies. Single-stranded DNA obtained using pUC118 and pUC119 is predominantly exploited in site-directed mutagenesis. This process leverages ssDNA's unique property wherein a single mutation introduced at a specific target site can lead to changes in the protein's structure and function. Thus, the process is essential when attempting to understand the role of particular amino acids in protein function and the impact of genetic mutations on diseases. Moreover, these vectors are used in DNA sequencing, the practice of determining the precise order of nucleotides within a DNA molecule. The production of ssDNA by pUC118 and pUC119 is crucial to Sanger's sequencing method, which requires a single-stranded template for the sequencing reaction. Furthermore, applications of these vectors extend to creating DNA libraries which are collections of DNA fragments from a particular genome and are useful in characterizing and comparing genomes. In this context, the pUC118/119 vectors are used to clone DNA fragments into their multiple cloning sites, enabling the creation of DNA libraries efficiently.
