$Fig. 5. Effect of chloride or nitrate on dense cells formed by O-D cycling. SS ND cells were O-D cycled for 22 hours at pH 6.8 in buffer containing chloride or nitrate, each with 0.5 mmol/L Ca2+. After O-D cycling, the cells were reapplied to density gradients and LD, ND, ID, and HD fractions were quantitated as described and defined in Fig 1. Results are presented for 15 SS patients where paired data were available. p calculated using the paired t-test (two-tailed).$
