Effect of HOCl on HSA and the ability to inhibit syncytium formation. To test the transformation effect of HOCl on HSA, mHSA samples were produced, which were generated using different HOCl:HSA ratios. The different mHSA preparations were tested for the inhibition of gp120/gp41-induced syncytia. HeLa-P4 cells were transfected with pSVATGrev plasmid expressing the NL4-3 (LAV) env. Syncytia were visualized by a standard staining procedure (Hemacolor®, Merck) and the nuclei of fused cells were counted. Shown are the averages of 6 wells.
