PREPARATIONOF2％FORMALDEHYDESTOCKSOLUTION(2METHODS)
METHOD 1:Formaldehyde preservative – 2% formaldehyde solution in protein-free phosphate-buffered saline (PBS).Prepare as follows:Add 2 g paraformaldehyde powder (e.g., Sigma, St. Louis, MO) to 100 ml of 1 X PBS. Heat to 70°C (do not exceed this temperature) in a fume hood until the paraformaldehyde goes into solution (note that this happens quickly as soon as the suspension reaches 70°C). Allow the solution to cool t......阅读全文
