WebAn improved ELISA-like assay was developed in which hyaluronidase activity could easily be detected in most biological samples ( 13 ). The general technique is described here, together with notes regarding more specialized usage. The free carboxy groups of HA are biotinylated in a one-step reaction using biotin hydrazide. WebDPPH inhibition ðÞ¼% ½ðÞA control A test =A control 100: The antioxidant activities of all extracts were finally expressed as an IC 50 value that is defined as the concentration (mg/mL) of extract showing 50% inhibition. The ABTS radical method (Lee et al. 2014) was slightly modified in order to evaluate the antioxidant effect of the samples. fencing blue mountains
