Common to all antibodies is the specificity they exhibit in binding to epitopes present on the surface of antigen in which ultimately a lattice formation results due to cross-linking. The present experiment exploits this interaction and is physically observed as …
The absorbance due to antibody is then the total absorbance minus the optical density due to the antigen added at equivalence. That is total absorbance at equivalence is 0. 68; the absorbance due to antibody is this total absorbance minus …
This investigation was adapted from the Fagot (1985) investigation where teachers and two-year-old children were studied to discover whether there were differences in the way teachers reinforced behaviour in boys and girls, and the effects of peer group reinforcement. The …
