Platinum Word Count: 472 Platinum is a relatively rare, chemically inert, metallic element. It symbol is Pt, atomic number is 78, and its atomic weight is 195.09. Platinum is one of the heaviest substances known. One cubic foot of Platinum weighs 21 times as much as a cubic foot of water. A grayish-white metal, Platinum has a melting point of 1772 degrees C and a realatively high boiling point of 3827 degrees C. It has a high fusing point, is ductile and malleable, expands slightly upon heating

The cell line was isolated from rat fetal intestinal epithelial cells and transfected with thermolabile SV40 large T antigen. These cells proliferated at 33 C, but eliminated the antigen and ceased proliferating at a non-permissive temperature (39C). At 39C 2/4/A1 cells s
