Abstract

The biochemical characteristics of dermal iridophore crystals from Anolis carolinensis have been investigated. Iridophores isolated by collangenase-hyaluronidase treatment were sonicated and their contents fractionated through sucrose. Pure iridophore crystals so obtained were examined by chromatography and electron diffraction. They were found to be pure hydrated crystalline form. The suggestion is made that the subcrystalline structure of this guanine does not play a role in color production by the iridophore.

摘要

对卡罗来纳安乐蜥的真皮虹彩细胞晶体的生化特性进行了研究。通过胶原酶-透明质酸酶处理分离出的虹彩细胞进行超声处理,其内容物通过蔗糖进行分级分离。对如此获得的纯虹彩细胞晶体进行了色谱分析和电子衍射检查。发现它们是纯的水合晶体形式。有人提出,这种鸟嘌呤的亚晶结构在虹彩细胞产生颜色的过程中不起作用。
