Purified tobacco class I, basic ß-1,3-glucanase. Purified GLU I consists of a mixture of closely related polypeptides encoded by a family of GLU I genes comprising GLA B5APL3 derived from the sylvestris ancestor of tobacco, GLB P27666 derived from the tomentosiformis ancestor of tobacco and homeologous recombinants (Sperisen et al., 1991). Mature GLU I is processed from a pre-pro-polypeptide (Shinshi et al., 1988).

Detection of tobacco tobacco class I ß 1,3 – glucanase in ng loaded per respective well using anti- tobacco class I ß 1,3 – glucanase antibodies. Primary antibodies have been used at 8 µg/ml.
For more details on immunolocalization, please referr to Keefe et al (1990). Plant 182: 43-51.
This antibody can be used as a marker of vacuolar contents Keefe et al. (1990). The effect of ethylene on the cell-type-specific and intracellular localization of β-1,3-glucanase and chitinase in tobacco leave. Plant 182: 43-51.
Important note: for blocking 5 % skim milk in PBS without Ca++ should be used.
This antibody is purified by affinity chromarography on Portein G.
Pathogenesis-related (PR) proteins, are induced in response to the infection of plants with microbial pathogens. Combinations of glucanase I and chitinase I are potent inhibitors of fungal growth in vitro however precise mechanism of that is still not known. Glucanase I and chitinase I contribute to defense against fungal infection and are currently used as markers for innate immunity, and in particular the ethylene/jasmonate signalling pathway in pathogenesis. Alternative names of the protein: basic beta-1,3-glucanase
