Open AccessExploring cellular memory molecules marking competent and active transcriptions
Development in higher eukaryotes involves programmed gene expression. Cell type-specific gene expression is established during this process and is inherited in succeeding cell cycles. Higher eukaryotes have ev...

A general method to modify BACs to generate large recombinant DNA fragments
Bacterial artificial chromosome (BAC) has the capacity to clone DNA fragments in excess of 300 kb. It also has the considerable advantages of stable propagation and ease of purification. These features make BA...

Knockdown of mouse adult β-globin gene expression in MEL cells by retrovirus vector-mediated RNA interference
RNA interference (RNAi) efficiently induces sequence-specific gene silencing in mammalian cells through short interfering RNA (siRNA) of 21–23 nucleotides synthesized in vitro or expressed by DNA-based vector....

Evaluation of optimal expression cassette in retrovirus vector for β-thalassemia gene therapy
Trials of retroviral vector-mediated human β-globin gene transfer were hampered by low titers, unstable vector transmission, and low-level expression of transferred gene. With the goal of optimizing the retrov...

Hot topics in adeno-associated virus as a gene transfer vector
Adeno-associated virus (AAV) is a promising viral vector in treating many kinds of hereditary diseases. The broad host range, low level of immune response, and longevity of gene expression observed with this v...

A fast and efficient method for isolation of the BAC end
As a new developmental vector system, the bacterial artificial chromosome (BAC) has been used widely in constructing genomic libraries and in generating transgenic animals. Isolation of the BAC insert end is u...

End-labeling of long DNA fragments with biotin and detection of DNA immobilized on magnetic beads
To immobilize DNA fragments onto magnetic beads coated with streptavidin for isolation purpose, it is important to label one biotin molecule at one terminus of DNA fragment. After failure to label long DNA wit...

Inversion and Transposition of Tc1 Transposon of C. elegans in Mammalian Cells
Tc1/mariner transposons are widespread in the eukaryotes. In vitro transposition test indicated that the transposase is the only protein that is needed in transpositions. It was shown later that ...
