چکیده

INTRODUCTION Guayule (Parthenium argentatum Gray, Asteraceae) is a woody desert shrub (Whitworth and Whitehead 1991) which is under commercial development as a domestic source of hypoallergenic natural rubber (Siler and Cornish 1994; Carey et al. 1995; Cornish 1996, 1998; Cornish et al. 1996, 2001; Schloman et al. 1996; Siler et al. 1996; Cornish and Lytle 1999). To expedite commercialization, factors affecting yield and stability of latex, in the harvested shrub prior to processing, must be understood in order to optimize and establish post-harvest storage conditions to maximize high quality latex yield (Cornish et al. 1999, 2000, 2001). Little is known about the effect of harvest season or post-harvest conditions on latex quality. Although latex quantification (Cornish et al. 1999) and large-scale (up to thousands of kilograms) purification methods are established (Cornish 1996), the investigation of parameters affecting latex quality require the development of methods suitable for the purification of latex from relatively small amounts of plant material. In this paper, we discuss latex allergies and describe latex purification methods for small (0.01–1.6 kg) and medium (1.6–30 kg) samples.

Quantitative Analysis of Anti-Hevea brasiliensis Antibody Cross-Reactivity against Taraxacum Kok-Saghyz Latex Proteins Demonstrates Significantly Reduced Antibody Recognition

The annual plant Taraxacum kok-saghyz, commonly called Russian dandelion, has recently gained commercial attention as an alternative source to the rubber tree, Hevea brasiliensis, for natural rubber latex. While producing rubber of equivalent quality, the potential application of TKS latex for hypoallergenic products remains to be determined. In order to quantify the allergenicity of TKS latex ...
