Applications of immunological methods to the analysis and detection of Lentinus lepideus Fr
1989 - IRG/WP 1422
Polyclonal antisera have been raised against the brown rot fungus Lentinus lepideus, a major cause of rot induced pole failure in the UK. Specificity studies have indicated that the antisera cross-react with a number of basidiomycetes but to much lesser extent with other fungi. The antigenicity of Lentinus lepideus and hence its molecular composition shows some alteration with culture age and chan...

Molecular analysis of the basidiomycete Coniophora puteana
1992 - IRG/WP 92-1534
Sodium dodecylsulphate polyacrylamide gel electrophoresis and Western Blotting, using a polyclonal antiserum produced against a whole cell extract of Coniophora puteana, were used to analyse the major proteins and antigens of the wet rot organism Coniophora puteana. The macromolecule profiles of this organism were different from other members of the Coniophora genus and from a set of unrelated org...

Dimensional lumber model demonstrates the sensitivity of the particle capture immunoassay in early detection of brown-rot fungi
1995 - IRG/WP 95-20058
A dimensional lumber model was designed to test the sensitivity of the particle capture immunoassay (PCI) compared to traditional methods of culturing and microscopic examination for detection of brown-rot fungi. Southern yellow pine 2 x 4's (5.1x10.2 cm²), and 86.4 cm in length, were inoculated on one end with the brown-rot fungus, Postia placenta, and tested over the full length of the...

Detection of brown-rot antigens in southern pine
1996 - IRG/WP 96-20090
Brown rot fungal antigens were detected by particle capture immunoassay (PCI) in southern pine 2 x 4's beyond visible or culturable hyphal growth. Further analysis of test samples revealed changes along the 2 x 4's that could be grouped into zones. Zone 1, the point of inoculation through 6 cm, showed low pH, measurable oxalic acid, high moisture, and high protein. Zone 2, throug...

Immunoassays for detecting and tracking wood-protecting chemicals
1998 - IRG/WP 98-50101-10
To respond to new environmental regulations, forest products industries are reducing or eliminating the release into the environment of chemicals used to protect wood products. For this, mills need tools that support practical and reliable programs for monitoring concentrations of wood protectants in processes and the environment. Conventionally, wood preservatives are detected mainly by gas-liqui...

Enzyme immunoassay to detect Postia placenta in field tests: Comparison of plate ELISA with hydrophobic cloth and cotton dipstick
1991 - IRG/WP 2378
Standard indirect enzyme-linked immunosorbent assay in polystyrene 96-well plates was compared to hydrophobic polyester cloth and cotton dipstick for detection of wood-derived antigens from the brown-rot fungus Postia placenta. The ease of handling, larger surface area, and economics of the latter two adsorbents were surveyed for application as field tests for detection of early decay. At high ant...

An immunoassay for benzyldimethyldodecylammonium chloride, a multipurpose disinfectant and fungicide
1997 - IRG/WP 97-30149
A competitive enzyme-linked immunosorbent assay (ELISA), based on polyclonal antibodies, was developed to measure benzyldimethyldodecylammonium chloride (BDDAC). The anti-BDDAC polyclonal antibodies recognized free BDDAC in an indirect competitive ELISA. The detection limit. based on the 20% inhibition (IC20), was 0.18 µg/ml and the 50% inhibition (IC50) was 1.1 µg/ml. The antibodies recognised ...

Use of the enzyme-linked immunoassay (ELISA) and immunocytochemistry to detect soft rot in preservative treated and untreated wood
1990 - IRG/WP 2347
A polyclonal antibody was raised against mycelial extracts from the soft rot fungus Phialophora mutabilis. In ELISA assays, the antibody showed strong reactions with its own antigen and strong to moderate cross reactions with 6 other Phialophora soft rot species. With the exception of Ceratocystis albida, the antibody gave only weak or negative reactions with 11 other mold, blue stain and rot fung...
