Allergen Details:

Allergen name: Hev b 2
Lineage: Source: Plantae Magnoliopsida
Order: Malpighiales
Species: Hevea brasiliensis (Para rubber tree (latex))
Biochemical name:beta-1,3-glucanase; glucan endo-1,3-beta-glucosidase, basic vacuolar isoform
MW(SDS-PAGE):35, 36.5 and 38 kDa
Allergenicity:Pubmed:9525455: Of 15 latex allergic patients, 6 (40%) reacted with purified nHev b 2 in immunoblot and ELISA. - PubMed:12372996: All sera of 34 latex sensitized patients also sensitized to nHev b 2 bound to three separated isoforms in ELISA. In immunoblot, only the glycosylated isoforms I and II, but not the non-glycosylated isoform III were recognized. In SPT, 3-4 of 7 patients reacted with the isoforms.
Allergenicity reference:952545512372996
Route of allergen exposure:Unknown
