The ability to edit the genome is essential for many state-of-the-art experimental paradigms. Since DNA breaks stimulate repair, they can be exploited to target site-specific integration. The clustered, regularly interspaced, short palindromic repeats (CRISPR)/cas9 system from Streptococcus pyogenes has been harnessed into an efficient and programmable(More)
Native tumours, in contrast to cell lines, are usually heterogeneous, consisting of tumour cells, stroma, infiltrating leukocytes, necrotic cells, and surrounding normal tissue. Therefore, when using non-linear amplification and detection methods such as the PCR, the verification of the DNA from the tumour cells is mandatory to avoid equivocal or false(More)
In this study, large numbers of hybridomas (produced by syngeneic immunization with B16 mouse melanoma and fusion with NS-1 myeloma cells) were screened for the production of antibodies that affected morphology and growth of animal and human tumor cells in vitro. Two such antibodies, NORM-1 and NORM-2 (both IgG2a), inhibited the growth of B16 melanoma cells(More)
beta-catenin is a multifunctional protein: it plays a central role in the cell-cell adhesive junctions, and participates in transduction of the morphogenic Wingless/Wnt-signal. Upon detailed analysis of the human beta-catenin gene, an intragenic polymorphic microsatellite marker could be identified. This marker shows 62% heterozygosity and was used in a(More)
Treating B16 mouse melanoma cells with monoclonal antibody NORM-2 reduces cell growth in tissue culture, agar, and syngeneic mice. We show that the NORM-2 antibody recognizes an integral 83 kd glycoprotein that is mobile in the plane of the plasma membrane of B16 melanoma cells. Expression of the glycoprotein is reduced under conditions that inhibit B16(More)
