A photovoltaic module is a grouping of connected solar cells used to collect energy from solar radiation. Each cell is electrically connected into these modules, which in turn are merged into a panel. When photovoltaic panels are installed at various locations they become known as arrays.
Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) isotype) that has only been found in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (Îµ chain) and two light chains, with the Îµ chain containing 4 Ig-like constant domains (CÎµ1-CÎµ4).
There are a number of different blood tests for IgE available: 1  Total IgE: this measures all IgE in the blood; this is not usually a helpful test, as a number of conditions cause IgE to be high (including eczema) and IgE levels do not necessarily relate to food allergy.
