I performed X-Rhod 1 staining for determining calcium concentration in rat brain mitochondrial fractions.
But, after calculations, in some samples the concentration is coming negative, which is ofcourse not right. I want to know the reason behind that ?
Rmax (flourescence intensity of calcium saturated sample) was coming less than R(flourescence intensity of my sample)
As far as i know, concentration cann't come in negative value.
But, after calculations, in some samples the concentration is coming negative, which is of course not right. I want to know the reason behind that ?
