The Murine Stem Cell Virus (MSCV) vectors, like pMSCVhyg, evolved from the confluence of the Murine Embryonic Stem Cell Virus (MESV) and the LN retroviral vectors. These vectors have been designed to convey stable, high-intensity gene expression in hematopoietic and embryonic stem cells owing to their uniquely crafted 5' long terminal repeat (LTR). This 5' LTR, derived from the murine stem cell PCMV virus, has several point mutations and a deletion that distinguish it from the MoMuLV LTR used in other retroviral vectors. These mutations and deletions significantly ameliorate transcriptional activation and thwart transcriptional suppression in embryonic stem and embryonal carcinoma cells. As a consequence of this intricate design, the LTR can drive strong, constant expression of a target gene in stem cells or other mammalian cell lines. This can only occur when the target gene is cloned into the multiple cloning site downstream of the 5' LTR. One significant feature of the pMSCVhyg vector is the integration of the hygromycin resistance gene. This gene is governed by the murine phosphoglycerate kinase (PKG) promoter (PPKG). This design enables antibiotic selection in eukaryotic cells, thereby facilitating more accurate and efficient research processes.
The pMSCVhyg vector is extensively used in several applications in the field of molecular biology, genetic engineering and medical research. Here are some of its applications: Gene Cloning: The pMSCVhyg vector is commonly used in cloning experiments due to its high cloning capacity, broad host range and compatibility with many different types of cells. Gene Therapy: The pMSCVhyg vector can be used to deliver therapeutic genes to a patient's cells. The delivered gene integrates into the genome of the host cells, allowing it to be expressed and potentially correct genetic diseases. Transfection: The pMSCVhyg vector is widely used for transfection in various cell types. This involves introducing foreign DNA into cells to study gene function and protein expression. Study of Gene Function: pMSCVhyg vector provides a tool for scientists to study the behavior of genes. By inserting a specific gene into the vector, researchers can observe the effects of that gene at a cellular level, providing invaluable insights into gene function. Production of Recombinant Proteins: The pMSCVhyg vector can also be used to produce large quantities of a protein by inserting the gene coding for that protein into the vector and introducing it into cells that can express the protein. Generation of Stable Cell Lines: The pMSCVhyg vector is often used to generate stable cell lines via retroviral infection. Cells that integrated the viral DNA can be selected using hygromycin, an antibiotic to which the vector confers resistance. This allows for the long-term study of a gene or protein of interest in the context of the whole organism.
Customer Q&As
Where were the MSCV vectors derived from?

A: The Murine Stem Cell Virus (MSCV) vectors were derived from the Murine Embryonic Stem CellVirus (MESV) and the LN retroviral vectors.

How does the LTR in the pMSCVhyg differ from other retroviral vectors?

A: The LTR in the pMSCVhyg differs from other retroviral vectors by several point mutations and a deletion, which enhance transcriptional activation and prevent transcriptional suppression in stem cells.

How does the pMSCVhyg achieve stable, high-level gene expression in stem cells?

A: The pMSCVhyg achieve stable, high-level gene expression in stem cells through a specifically designed 5' long terminal repeat (LTR) derived from the murine stem cell PCMV virus.

Does pMSCVhyg contain the necessary genes for particle formation and replication?

A: No, pMSCVhyg does not contain the gag, pol, and env structural genes necessary for particle formation and replication.
