Dear flowers, i am using FITC conjugated E.coli bugs for standardization of phagocytosis assay for mouse peritoneal macrophages....for each of the treatment conditions i ahve been using, i use 4 degree treatment as negative control...with increase in time and number of bugs i am facing the problem of shift in 4 degrees control and hence the positive shift gets narrower...i tried things like...prechilling the negative control plates before the adition of bugs...but it's of no use..... could you please help me?.... thanks in advance.... veeru
