Aging of Spider Silks

[摘要] References(8)Cited-By(12)Effect of ultraviolet rays on drag lines, which were secreted at different life stages of spider Nephila clavata, was studied from the aging point of view. The radicals due to the degradation of protein molecules were measured as a function of the irradiation time of ultraviolet rays and the spider age by the electron spin resonance ESR method. It was found that the radical intensity for drag lines from the mature spiders was larger than that from the juvenile spiders. This finding suggests that the aging should be considered for the silks secreted from the old spiders.
