Preparation Note
该产物是通过Niyibizi, C., et al., J. Biol. Chem., 259, 14170 (1984)的胃蛋白酶提取和盐分级分离法的改进制备的。它是一种酸溶性胶原，可以溶解在水中，并添加乙酸到pH值3.0（5 mg/mL），产生乳白色无色溶液。
Analysis Note
SDS聚丙烯酰胺凝胶电泳在和基底膜胶原蛋白相同的还原条件下测试，得到三条主要条带。
Other Notes
所有胶原蛋白分子均由以三螺旋构象排列的三条肽链组成，其一级结构主要以三个氨基酸作为重复基序，即每隔两个氨基酸是一个甘氨酸残基，其前面的两个位置通常为脯氨酸或4-羟基脯氨酸。
胶原蛋白被分为许多种结构和遗传性不同的类型。 我们使用 Bornstein和Traub提出的系统命名法。 小心不要混淆Sigma命名系统和通用的胶原蛋白分类类型。
Disclaimer
该产品应在-20℃下干燥保存，在此条件下可保持活性3年。

Topography-guided laser refractive surgery regularizes the front corneal surface irregularities to achieve the desired refractive outcome. This is particularly applicable in highly aberrated corneas, where wavefront aberrometry is often not possible. This article aims to review the recently published results
