I do appreciate if any one could suggest any way to count the number of cell/ml because I want to have equal amount of rabbit myocytes in order to infect them with adenovirus. Thanks
I have no experience doing this myself, but I am just wondering - why don't you use a trypsin protocol (or collagenase) in order to digest the hearts and get the cardiomyozytes in solutions. Then you can simply count them with a haemocytometer to get the cell concentration and adjust it accordingly.
Another member in my lab did the rabbit isolation and gave me the cell suspension. I have tried counting with hemocytometer but the rabbit myocytes are too big, in comparison to the rat myocytes. And before add in the viral cocktail, I also wash the cells one time which means I also lose a number of cells.
there are gridded coverslip from Electron Microscopy Services. It is not as accurate as the hemocytometer, but you can have an idea of the density (myocytes per square unit of your choice)
the more convential way is used neubauer chamber, but i think the cells used are bigger for the chamber
other way not so easy but cheap is used a cutlure plate of 24 well, the have especific are fro cell growht and you can made a calibration of your objetive (used all the área for calculated diameter) and observed all the well, then you can made a reltion of number cells by área and obtenied a value for you problema. Of course I suggested used a second calibration and diluted your DNA in different well for obtenied the efficences of you tranfection
