In Biomaterials Testing, a cell culture assay is any method which is used to assess the cytotoxicity of a material. This refers to the in vitro assessment of material to determine whether it releases toxic chemicals in sufficient quantities to kill cells either directly or indirectly through the inhibition of cell metabolic pathways. Cell culture evaluations are the precursor to whole animal studies and are a way to determine if significant cytotoxicity exists for the given material. Cell culture assays are standardized by ASTM, ISO, and BSI (British Standards Institution.)
Famous quotes containing the words cell, culture and/or assays:
“What Mrs. Thatcher did for women was to demonstrate that if a woman had enough desire she could do what she wanted, do anything a man could do.... Mrs. Thatcher did not have one traditional feminine cell in her body.”
—Julie Burchill (b. 1960)
“I am writing to resist the view that Europe and civilization are going to Hell. If I am being “crucified for an idea”Mthat is, the coherent idea around which my muddles accumulated—it is probably the idea that European culture ought to survive, that the best qualities of it ought to survive along with whatever cultures, in whatever universality. Against the propaganda of terror and the propaganda of luxury, have you a nice simple answer?”
—Ezra Pound (1885–1972)
“Your bait of falsehood takes this carp of truth,
And thus do we of wisdom and of reach,
With windlasses and with assays of bias,
By indirections find directions out.”
—William Shakespeare (1564–1616)
