Heterogeneity of Hemolytic Efficiency and Isoelectric Point of Streptolysin 0

serum and their molecular weight. The SLO components showed a single molecular weight of 64,000, but they exhibited various pls ranging from pH 5.4 to 8.3, with major components showing a pI of 6 and/or 7.5. Further examination revealed the slope of the hemolytic titration curve to be dissimilar among the samples of crude SLO. Since the slope of the… CONTINUE READING
