Hemocytometer equation
WebI am taking 10ul of sample in hemocytometer and counting 5 squares ie. 4 from corner and 1 from center. Problem arises while calculating dilution factor . Suppose I have counted 120 spores in total 5 squares using 10ul of sample from dilution tube 10-1 then what would be the dilution factorand please also clear me the formula used. Web1. For "X" cells, take sample after harvesting the cells, 2. Take 10ul trypan blue in a microtube+ 10ul cell sample…..there should not be any bubbles. 3. Mix it well without any bubbles. 4. Take...

WebNo formulas involved – we just deduced what the cell density is based on hemocytometer dimensions. Extending this to the general case, the formula would be cell density = (total cells counted / number of squares counted) / volume of a single square – that doesn’t account for any dilutions carried out.
