Sequential IgE-binding epitopes were identified on the molecular surface of Pis v 1 (2S albumin), 2 (11S globulin/legumin) and 3 (7S globulin/vicilin)—major allergens from pistachio (Pistacia vera) seeds—using Spot technique. They essentially consist hydrophilic electropositively charged residues well exposed allergens. Most epitopic regions do not coincide with putative N-glycosylation sites t...

The Amerlex Free Thyroxin (T4) Radioimmunoassay Kit (Amersham International Ltd.) is a new direct equilibrium radioimmunoassay for free T4 based on an antiserum with very high affinity for T4, and a unique 125I-labeled T4 analog as tracer. It is a very simple single-tube radioimmunoassay, making use of Amerlex particles to separate antibody-bound from free species. Interassay precision (CV) is ...

The effect of varying concentrations (0-52 mg/l) of purified thyroxine binding globulin (TBG) on the microencapsulated antibody method for free thyroxine was investigated. The results demonstrated that the free thyroxine values were strongly influenced by the concentration of thyroxine binding globulin in the samples. The standard curve could no longer be distinguished at a concentration of pur...
