The 6-phosphofructo-1-kinase (PFK) subunits and isoenzymes were studied in human muscle, heart, brain, liver, platelets, fibroblasts, erythrocytes, placenta and umbilical cord. In each tissue, the subunit types in the native isoenzymes were characterized by immunological titration with subunit-specific antibodies and by column chromatography on QAE(More)
The SER allows the "deformability" of individual red blood cells to be quantitated by determining their passage time through a pore (d = 5.8 microns, 1 = 50 microns) under the shear stresses of 1.5 Pa-4 Pa. Using this system, we examined the influence of: 1. cytoplasmic viscosity, 2. membrane viscoelastic properties, 3. area to volume relationship. To(More)
