However, it is also very useful for cloning attachment dependent cells when the cell plating efficiency is very low, unknown or unpredictable. Originally described by Engvall and Perlmann (1971), the method enables analysis of protein samples The newest protocol for the treatment of filler embolism involves several important changes. It is a method of diluting a stock solution where concentration decreases by the same quantity in each successive step.
