Tumor promoters such as phorbol esters, teleocidin and okadaic acid increase the numbers of multilayered, transformed foci produced by BPV DNA-transfected C3H/10T1/2 cells. We questioned whether arsenic and chromium, which are known human carcinogens also enhance transformation of BPV DNA-transfected
The ultrastructure of endochondral bone was studied using an aqueous solution of chromic potassium sulphate as the decalcifying agent. 0.5 mm thick sections of rat tibiae were fixed in buffered glutaraldehyde, immersed in an aqueous solution of 1% chromic potassium

Various pretreatments of metaphase spreads were examined to obtain optimal DNA labelling patterns while maintaining chromosome integrity during in situ hybridization procedures. Preparations of African green monkey (AGM) chromosomes fixed in methanol-acetic acid (CV-1 cell line) were treated by coating

Gallocyanine-chrome alum-stained pig embryonic kidney cells have paramagnetic properties. They move under the influence of gradient magnetic field (magnetophoresis). The velocity of magnetophoresis is proportional to the content of nucleic acids in cells. This allows to estimate the content of
In situ as well as extra situm cytochemical methods were used to investigate why the observed Feulgen-DNA value of sperm versus lymphocyte cells is lower than expected. After treatment with 5 N HCl, in situ experiments involving the GCA reaction
