摘要： Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

摘要： Provided herein are organic solvent-based processes for the removal of rubber from aged briquettes made from compressed plant matter (briquettes) of non-Hevea plants. Also provided are aged briquettes made from the compressed plant matter of non-Hevea plants where the briquettes have been aged for either various time period after formation and the rubber within the briquette has retained its a molecular weight to within a specified range.

摘要： Processes for recovering natural rubber from an aqueous natural rubber latex that contains extractables and one or more additives and that is essentially free of lignocellulosic plant material are described. Natural rubber in the latex is separated from the water. Preferably, the amount of non-rubber extractables in the natural rubber is reduced by one or more extraction steps yielding a dried natural rubber.

摘要： This invention relates to allergenic proteins of natural rubber latex in substantially purified form, their production and their use, together with monoclonal antibodies developed against those allergenic proteins, in assays for the qualitative and quantitative determination of the levels of the allergenic proteins in natural rubber latex or in products made from latex. Assays for identifying and/or quantitating antibodies in blood or blood products that mediate the occurrence of an allergic reaction induced by natural rubber latex are also provided, together with in vivo and in vitro diagnostic tests for detecting hypersensitivity to natural rubber latex and which involve use of the aforesaid allergenic proteins. The invention also provides for the use of the aforesaid allergens as de-sensitising agents in the treatment of latex protein allergy. There is still further provided a method for removing allergenic proteins from latex products.
